Construir navios havia sido, desde sempre, uma atividade regida pela mais inveterada empiria. O aparecimento das primeiras normas escritas nos textos italianos do século XV marca o princípio da época que poderíamos chamar das instruções técnicas, ou, como acontece no caso português, da tratadística, um período que vai, grosso modo, dos meados do século XV aos finais do XVII. As instruções técnicas mais ou menos extensas fornecem regras geométricas para a construção do casco do navio, embora não ainda de uma forma completa, como aconte­cerá com os tratados do século XVIII, que inauguram uma terceira fase, em que o estudo do navio contempla a geometrização total do seu desenho. A parte mais importante do navio passa a ser o seu desenho técnico, como perceberam desde logo os engenheiros cons­trutores navais.

O Livro da Fábrica das Naus é o primeiro exemplo europeu de um manual de construção naval exclusivamente dedicado a navios de alto bordo, ou seja, para a navegação oceânica, e, espe­cificamente neste caso, a navios da que se chamou depois tradição ibero-atlântica. […] Apesar de inserir desenhos no Livro, Oliveira não alude à necessidade de planear o navio em desenho ou da construção prévia de um modelo. Em contrapartida, comporta aspetos de uma enorme importância que destacam o seu carácter único. Um deles é, sem dúvida, a parte inicial do texto, em que o autor fundamenta as condições do conhe­cimento. Trata-se do único autor de um tratado de construção naval deste período que ultrapassa o nível de consideração do que se sabe para discutir o como se sabe e o porquê. Um bom exemplo desta fundamentação teórica é a afirmação do postulado aristotélico de que a perfeição é um atributo divino que não cabe na dimensão do humano, logo, os homens não podem fazer navios perfeitos; mas, como Deus criou um animal com a forma perfeita para andar no mar – o peixe –, então a forma do casco dos navios deve imitar a forma do corpo dos peixes, ou seja, a forma perfeita para andar na água – hidrodinâmica, dir-se-ia hoje.

O Livro refletia a prá­tica dos estaleiros, tornando-se assim um instrumento fundamental para o estudo do saber-fazer da época. […] A obra permanece como um exemplo notável da tratadística europeia de arquitetura naval, não tendo existido até à data da sua composição obra alguma que se lhe equiparasse do ponto de vista da ilustração.

The Third International Congress of Eurasian Maritime History, organised by the Pîrî Reis University and held on May 10-11, 2018 in Istanbul, was an important step in reviving interest in maritime history by bringing together researchers from many countries. This scientific event has been successfully realized thanks to the invaluable support of the Turkish Chamber of Shipping, Turkish Shipbuilding’ Association (GISBIR), Türk Loydu and the Turkish Foundation for Underwater Archaeology (TINA).

This collection of essays brings together various research works related to these ships and the world in which they were built and sailed. It features a collection of works carried out by a network of experts on the fields of History, Archaeology, Anthropology, and associated disciplines. The result summarizes a body of work that we had not planned to achieve, but that was developed beyond and above the goals we had set up and achieved for ForSEAdiscovery. We had not anticipated how well we worked together, the synergies we created, and the sense of community we developed. As it stands, this book is a summary of what we learned about these incredible machines – oceangoing ships – and the people who built and sail them. In this sense, it is intended as a set of incremental contributions to our knowledge, and not as a treatise on Iberian navigation in the early modern age, which would require a much more extensive work, and would probably be useless in one decade or so.

A utilidade dum inventário como o que aqui se apresenta é inquestionável. As perguntas mais relevantes que se nos afiguram no início deste trabalho são as relacionadas com a forma de datar os cepos de âncora inventariados, de saber se estão associados a sítios de naufrágio, se a sua localizacao está mais associada com locais de mergulho desportivo do que com a morfologia da costa. Seguem-se as questões óbvias, relacionadas com as dimensões e pesos dos cepos, as tipologias, ou as profundidades a que foram encontrados. Por fim será interessante saber se há formas de relacionar a coleção portuguesa com coleções de outras zonas costeiras europeias ou se há formas de relacionar os tamanhos e pesos dos cepos com os dos navios que os transportavam.
Provavelmente reutilizados desde a antiguadade clássica, os cepos encontrados por comunidades ribeirinhas deve ter sido fundidos e utilizados com outros fins. O primeiro cepo encontrado em Portugal de que há notícia foi alegadamente fundido para fazer pesos para mergulho.
Utilizados entre o século VI BCE e o século III CE, os cepos de âncora em chumbo têm sido objecto de recuperação por empresas ligadas á indústria nuclear e fundidos em grandes quantidades. A procura de chumbo com proveniência arqueológica é aparentemente enorme e há caçadores de tesouros especializados na recolha de objectos de chumbo para aquela indústria.

Shipwreck stories have the potential to attract the attention of a wide public in different ways. Based on the Portuguese situation, of a country with a mythical past connected to the sea but a public policy for maritime archeology that lacks vision, purpose, or strategy and tends to exclude the public, this paper proposes a reflection on the social value of archeology and the potential it has for education and entertainment.

Sunk in 1804 by the British Navy off the coast of the Algarve, the frigate Nuestra Señora de las Mercedes has become a myth for treasure hunters in the second half of the 20th Century.
Although her cargo can hardly be considered a treasure, the history of her loss and the stories of the adventurers who tried to gather funds to find and recuperate her remains, make this case an interesting example for the discussion of the questions related to the archaeology of ships with treasure (real or imaginary),
the activity of treasure hunters and the fragile condition of the underwater cultural heritage of the waters of the Exclusive Economic Zone, outside the territorial waters.

This talk will focus on the importance of the maritime cultural heritage and the challenges and opportunities created by the find, recording, excavation and publication of archaeological finds. It will make the point for the importance of the submerged cultural heritage, the reasons to preserve it, the value of archaeological remains, the importance of sharing them with a diverse public, the best ways to share and protect it, and the basic rules to reconstruct historical environments.

It is difficult to imagine a healthy society without a history, a common memory, or a common cultural background.  In many countries history and archaeology have provided society with a sense of unity and continuity, at least since the advent of the Enlightenment.  However, reconstructing the past based on documents and material remains is not an easy endeavor.  Every generation of historians and archaeologists works to reconstruct the past with the means available, and every time the result is different. 

During the 20th century historians have reflected on the means and purposes of History and have radically transformed the discipline, partly by changing the questions asked, and partly by including the inputs of geography, economy, sociology, anthropology, and philosophy.  Similarly, archaeologists have widened the array of supporting disciplines, and today archaeological studies are regularly supported by hard data and their hypothesis tested under the highest scientific standards.

The cooperation between archaeologists and hard scientists is not always easy, however.  Traditionally divided until well after the Second World War, the Sciences and the Humanities were largely perceived as different scholarly worlds, rather independent, and ruled by different standards.  This non-overlapping magisteria – as Stephen Jay Gould would call it – determined marked differences between the scholars of these “two cultures” – in the famous words of Charles Pierce Snow – which extended into their social lives.  According to C. P. Snow’s famous 1959 University of Cambridge Rede Lecture, scholars from “the two cultures” exhibited a prodigious ignorance of each other’s knowledge and almost never saw each other socially.

Half a century later the situation is rater different and nautical and maritime archaeology are perhaps one of the fields of study where the role of hard sciences has grown in a more pronounced way.  Yet, at least in the U.S.A., universities have shown an incredible lack of interest in this kind of multidisciplinary projects – although most deans claim otherwise – and the curricula remain as separated as ever.

The India Route was one of the longest commercial routes of the sixteenth century, and the Portuguese ‘naus’ designed and built to sail it were among the best and largest ships of their time. Perhaps less than 250 Portuguese Indiamen were lost from 1498 to 1640, and many were found and burned soon after the wrecking event, to recover the expensive iron fastenings. This paper addresses the significance of oceangoing construction in the context of Europe’s history of science and ideas.

É comum dizer-se que a chamada Era dos Descobrimentos Marítimos - espoletada em meados do século XV por dois países europeus até então periféricos - iniciou a primeira era de globalização mundial. Com efeito, ao colocar as mais variadas culturas e os mais diversos povos em contacto directo - quer pelo conflito, quer pelo comércio - e ao criar novas rotas capazes de fazer disseminar a uma escala planetária plantas, animais, recursos naturais, manufacturas, crenças e ideologias, Espanha e Portugal deram efectivamente novos mundos ao Mundo.
No decurso dessa globalização, Portugal enviou para Oriente não só alguns dos seus melhores - Gama, Camões, Fernão Mendes Pinto, Garcia de Orta, Albuquerque, entre tantos outros - mas também muito dos seus deserdados e esquecidos: filhos segundos da baixa nobreza, agentes da Coroa empobrecidos, criminosos condenados a degredo ou mulheres da mais baixa condição; no fundo, todos aqueles que viam nas miríficas riquezas e paragens asiáticas uma oportunidade de ascensão social ou uma oportunidade de ganhar honra, fama e futuras mercês e tenças pelos serviços prestados a el-Rei na defesa do seu Império marítimo.
Ora, sendo marítimo esse Império, fundamentais eram os instrumentos que permitiam o seu domínio e expansão. Naus, caravelas e galeões foram as ferramentas com que Coroa e Reino controlaram territórios e dominaram rotas, com os navios ibéricos dos séculos XV e XVI a desbravarem as grandes vias transoceânicas do mundo, ligando a Europa aos oceanos Atlântico, Índico e Pacífico e estes aos círculos polares ártico e antártico.

It is common to say that the era of the voyages of discovery – unleashed in the mid-15th century by two, until then, peripheral nations – began the first era of globalisation. In fact, by bringing the most varied of cultures and peoples into direct contact – either through conflict or trade – and by creating new routes able to disseminate plants, animals, natural resources, manufactured goods, beliefs and ideologies at a planetary scale, Spain and Portugal effectively gave the World new worlds.
During the course of this globalisation, Portugal not only sent some of its finest sons to the Orient – Gama, Camões, Fernão Mendes Pinto, Garcia de Orta, Albuquerque, amongst many others – but also many of its disinherited and forgotten: second sons of the lower aristocracy, impoverished agents of the Crown, criminals banished from the realm and women of low morals; essentially all those who saw the wondrous riches and Asian destinations as an opportunity to rise up the social ladder or a chance to earn honour, fame and future mercies and stipends for services rendered to the king in defence of his maritime empire.
Since this empire was maritime in nature, the instruments of its domination and expansion were fundamental. Naus, caravels and galleons were the tools used by the Crown and Realm to control territories and dominate routes, with the Iberian ships of the 15th and 16th centuries braving the world’s great trans-oceanic highways, linking Europe to the Atlantic, Indian and Pacific oceans and these to the Arctic and Antarctic.

ShipLAB Report No. 29 - Draft 01, November 2018. 
When studying shipwrecks, archaeologists analyze the archaeological material in light of contemporary texts and iconography. Ships have been drawn and painted around the world and images representing watercraft can date as far back as the earliest civilizations. Artists have used many supports to create representations of ships and boats, including rock carvings, sculptures, models, drawings, graffiti, and paintings. These images provide us with information on how contemporary individuals viewed ships, and their interaction with the sea.

Almost three decades ago J. Richard Steffy (in: Tzalas (ed) Tropis II, pro- ceedings of the 2nd international symposium on ship construction in antiquity. Athens, pp 315–320, 1990, in: Tzalas (ed) Tropis III, proceedings of the 3rd international sym- posium on ship construction in antiquity. Athens, pp 417–428, 1995) voiced the need to standardize the recording and publication of shipwrecks. Cluster analysis of construction features is difficult if archaeologists record different and non-overlapping features. This paper discusses the necessity to standardize the recording and publishing of a set of consistent and compatible basic construction features when archaeologists assess, survey, or excavate wooden shipwrecks and proposes a methodology for the recording of wooden hulls. It also emphasizes the urgency of a wide and complete sharing of archaeological information in maritime archaeology.

Caravels are among the most poorly understood historical craft.  Mentioned in hundreds, perhaps even thousands of books, these ships have never been thoroughly described in historical sources, their representations are few and not very detailed, and no caravel has been archaeologically excavated to this day.  Replicas have been built with mixed results, never based on solid supporting information. This paper is a tentative summary of what is known about these ships.

Se há navio que mais simboliza o dealbar da era dos Descobrimentos ele é, sem dúvida, a caravela, nas suas mais diversas conjugações e configurações.

Uma destas derivações seria a do caravelão – uma das embarcações mais ubíquas de então mas, simultânea e paradoxalmente, uma das mais hodiernamente desconhecida.

Com efeito, o desafio que se apresenta ao investigador que pretende estudar os navios e as embarcações que sulcavam as costas e os rios de Portugal nos séculos XV e XVI é, para além de difícil, também desconcertante. De facto, para além de uma quase total ausência de dados concretos relativos a muitos tipos de embarcações (dos quais não existe, amiúde, muito mais que a sua denominação) verifica-se também toda uma miríade de formas e soluções estruturais evoluiu, transformou-se e, em alguns casos, desapareceu ou reinventou-se ao sabor de modas, acidentes e necessidades socioeconómicas, de porto para porto e de década para década. Finalmente, para complicar ainda mais algo já de si complexo, um mesmo navio pode ser designado de maneiras diferentes, dando-se nomes idênticos a navios distintos ou com, pelo menos, características muito bem diferenciadas.

Assim, a escassez de dados documentais, iconográficos e arqueoló-gicos dificulta o desenvolvimento de uma taxonomia e,
talvez mais importante do que uma taxonomia, uma cladística das famílias e variedades das embarcações deste período – até porque aquilo que se tem vindo a saber pelo estudo da documentação deixada pelos cronistas, notários e escrivães coevos – muitas vezes pouco conhecedores das subtilezas tecnológicas que diferenciavam as distintas tipologias navais – dificulta mais do que facilita o estudo do processo de evolução das embarcações e respectivos nomes.

Neste contexto, não só é confuso tentar saber o que diferenciava uma caravela de um caravelão, em finais do século XV, como é extremamente complicado perceber o que eram uma e outra embarcação, em termos tão simples como dimensões, tonelagem e aparelho vélico.

Questions associated with the size of ships suggested in historical documents are relevant to giving an idea of the volume of cargoes, the size of crews, cost of freights, or when trying to evaluate competitive advantages in war and commerce. Good estimates are often difficult to obtain from the written record, although some values concerning basic hull dimensions are sometimes mentioned. The establishment of reliable relations between registered capacity, as expressed in coeval documents, and displacement, as it is defined nowadays, would be helpful to both historical and archaeological research. This paper probes
into the relations between a number of known formulas to calculate tonnages in the 16th century, and the reconstructed hull of the Pepper Wreck, an archaeologically excavated shipwreck dated to 1606.

Methods of designing the bottom of ship’s hulls were only a small part of the process of building a frame-based ship in Portugal
in the 16th and early 17th centuries, but they deserve a careful look. Using a number of geometric algorithms that were already
well-known to Italian shipwrights of the 15th century, Portuguese shipwrights obtained the co-ordinates of the turn of the
bilge points of the central, pre-designed, frames without the need for making drawings.

L'identification à Montréal d'un astrolabe nautique inconnu des spécialistes a motivé un examen de ces instruments conservés au Canada et en France. L'astrolabe nautique permet la prise d'élévation du soleil ou de l'étoile polaire et, ainsi, le calcul de la latitude où l'on se trouve. Celui de Montréal, fabriqué à Lisbonne en 1631, appartient à la collection historique des pères sulpiciens. Le contexte de son acquisition étant inconnu, ce travail évalue son lien possible avec les sulpiciens René Bréhant de Galinée, navigateur, et Jean Cavelier, frère du célèbre explorateur Cavelier de La Salle. L'étude considère ensuite l'instrument au sein du corpus de 11 astrolabes nautiques connus en sol canadien et français. Fabriquées en Espagne, en France et au Portugal, ces pièces jettent une lumière sur l'évolution des pratiques de navigation dans l' Atlantique septentrional aux xvi e et xvii e siècles. Ce travail identifie Honfleur comme lieu de fabrication en France. Les astrolabes nautiques participèrent à la construction sociale d'un savoir maritime scientifique lié à l'État, processus impliquant des ordres religieux dont celui des sulpiciens de Montréal. • The identification in Montréal of a nautical astrolabe previously unknown to specialists has prompted a new look at instruments of this type held in Canada and France. Mariners used the astrolabe to measure the elevation of the sun or the North Star and thus calculate their latitude. Cast in Lisbon in 1631, the Montreal instrument belongs to the historical collection of the Sulpician fathers. Since the context of its acquisition is unknown, this study examines a possible link with two Sulpicians-René Bréhant de Galinée, navigator, and Jean Cavelier, brother of the famous explorer Cavelier de La Salle. This research then considers the instrument within the corpus of 11 nautical astrolabes known in Canada and France. Made in Spain, France, and Portugal, these pieces shed light on the evolution of navigation practices in the North Atlantic in the 16th and 17th centuries. This study identifies Honfleur as a production centre in France. Nautical astrolabes played a role in the social construction of scientific maritime knowledge tied to the State, a process that involved religious orders, including the Montréal Sulpicians.

Marine astrolabes were a simplification of the existing Islamic calculating devices and were used during the sixteenth and seventeenth centuries to measure the height of the sun at noon on sailing ships. With this value and the proper tables, sea captains could calculate the latitude and estimate the position of their ships during the long oceanic voyages that characterized the first age of globalization. This paper presents an inventory of all marine astrolabes known to exist, and proposes a taxonomy and chronology of their styles, based on the available data.

The Rio Grande do Norte astrolabe may have been found in Brazilian waters, although its provenance is unclear. It was bought and sold at auction in the Unites States in 2011, and the instrument represents a well-preserved specimen within a small and poorly understood collection of published marine astrolabes. It is signed by Agostinho de Goes Raposo, a member of a line of documented Portuguese astrolabe makers, and dated to 1656. This paper relates the condition, treatment, and ethical situation of the artifact, and hopes to advance our understanding of this class of navigation instruments.

Data sharing is a fundamental process for the advancement of both natural and social sciences. This paper explains the creation of the Nautical Archaeology Digital Library (NADL: https://nadl.tamu.edu/) and its efforts to standardize information collection for maritime archaeology projects, shipwrecks and related sites and to disseminate that information. Our purpose is to generate a common-ground methodology and terminology that promotes an intelligible dialogue within the global community of underwater archaeologists. The paper starts by defining archaeology as scientifically-built knowledge using definitions provided by philosophers of science. It addresses some considerations on terminology and systematization in scientific disciplines and discusses the theoretical and methodological issues encountered in the process of creating the templates to recording maritime archaeology projects and shipwrecks. Lastly, it discusses how science is greatly enhanced by the publication of information in easy accessible open source platforms.

In the 15th and 16th centuries European ships set out to explore and map the planet, bringing together populations, ideas, plants, animals, foods, flavors, scents, and worldviews.

As J. Richard Steffy used to say, ships carried people, merchandise, and ideas.

This project aims at understanding the ships of this period, how they were thought of, designed, built, and how they changed as knowledge of the oceans and coasts of the world increased.

This project aimed at developing a digital library of artifacts gathered in the domain of Nautical Archaeology and using it to examine tools and their application in the day-to-day scholarly practice in the area. The specific goal of the project was to design, implement, and evaluate a framework that would:

- efficiently catalog, store, and manage artifacts and ship remains along its associated data and information produced by an underwater archaeological excavation;
- integrate heterogeneous data sources from different media to facilitate research work and handle uncertainty in data and structure;
- incorporate historic sources to help in the study of current artifacts
develop visualization tools to help researchers manipulate, observe, study, and analyze artifacts and their relationships;
- develop algorithm and visualization based mechanisms for ship reconstruction, i.e., to determine where recovered pieces and fragments fit in a whole.

The project was a collaborative effort of researchers in Texas A&M University's Center for the Study of Digital Libraries (CSDL) and Nautical Archaeology Program (NAP). The project drew its materials from the extensive collection of artifacts gathered from a shipwreck in Portugal as well as the extensive archives collected at the NAP during field studies over the past 32 years.

This project was based upon work supported by the National Science Foundation under Grant No. IIS-0534314. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.

Archaeologists reconstruct past human activity from material culture remains. Recording, representing and reconstructing artifacts or contexts is a long, morose, and often expensive process. Computers have radically changed traditional methodologies and are creating opportunities to develop more eloquent images or graphic files that convey compressed information and engage the public in a more participative way. Archeological reconstructions are thinking tools that allow us to reason better and faster about our past and present, and computer graphics can replace the traditional long texts and orthographic images with a rich learning environment that transforms the learning experience into an active and critical mental process.  This chapter analyses the current methodologies and evaluates the cost-benefits of the best off-the-shelf software packages and their potential to improve the recording, representing, reconstructing, and sharing archaeological contexts and artifacts.

This chapter analyses the functionality and applicability of procedural computer-based modelling techniques in the field of nautical archaeology. To demonstrate this approach, an interactive procedural model of the lower hull timbers of a sixteenth-century European merchant ship was developed through a process of prototype implementation, and an evaluation of the usefulness and effectiveness of the prototypes developed was carried out using the timbers from the hull remains of the Belinho 1 shipwreck, found in Portugal in 2014. The 3D model was created using Houdini, a procedural node-based 3D software package. A basic collection of the main timber components of a ship’s lower hull was defined, and functional rules were created for each timber, based on real-world ship design and construction processes. Then the rules were incorporated into the logic of the procedural modelling algorithm, and the resulting model was changed by using the Belinho 1 shipwreck scantlings. The results, which will be discussed, were satisfactory, except for the planking, which is a very complex part of the shipbuilding process and deserves future attention.

Cultural heritage (CH) resources are very heterogeneous since the information was collected from vast diversity of cultural sites and digitally recorded in different formats. With the progress of 3D technologies , photogrammetry techniques become the adopted solution for representing CH artifacts by turning photos from small finds, to entire landscapes, into accurate 3D models. To meet knowledge representation with cultural heritage photogrammetry, this paper proposes an ontology-profiling method for modeling a real case of archaeological amphorae. The ontological profile consists of all needed information to represent a CH resource including typology attributes, geo-spatial information and photogrammetry process. An example illustrating the applicability of this profiling method to the problem of CH resources conceptualization is presented. We also outline our perspectives for using ontologies in data-driven science, in particular on modeling a complete pipeline that manages both the photogrammetric process and the archaeological knowledge.

The project iMARECULTURE is focusing in raising European iden‐ tity awareness using maritime and underwater cultural interaction and exchange in Mediterranean Sea. Commercial ship routes joining Europe with other cultures are vivid examples of cultural interaction, while shipwrecks and submerged sites, unreachable to wide public are excellent samples that can benefit from immersive technologies, augmented and virtual reality. The projects aim to bring inherently unreachable underwater cultural heritage within digital reach of the wide public using virtual visits and immersive technologies. Apart from reusing existing 3D data of underwater shipwrecks and sites, with respect to ethics, rights and licensing, to provide a personalized dry visit to a museum visitor or augmented reality to the diver, it also emphasizes on developing pre-and after-encounter of the digital or physical museum visitor. The former one is implemented exploiting geospatial enabled technologies for developing a serious game of sailing over ancient Mediterranean and the latter for an underwater shipwreck excavation game. Both games are realized thought social media, in order to facilitate infor‐ mation exchange among users. The project supports dry visits providing immer‐ sive experience through VR Cave and 3D info kiosks on museums or through the web. Additionally, aims to significantly enhance the experience of the diver, visitor or scholar, using underwater augmented reality in a tablet and an under‐ water housing. The consortium is composed by universities and SMEs with expe‐ rience in diverse underwater projects, existing digital libraries, and people many of which are divers themselves.

Cultural heritage (CH) resources are very diverse, heterogeneous , discontinuous and subject to possible updates and revisions in nature. The use of semantic web technologies associated with 3D graph-ical tools is proposed to improve the access, the exploration, the mining and the enrichment of this CH data in a standardized and more struc-tured form. This paper presents a new ontology-based tool that allows to visualize spatial clustering over 3D distribution of CH artifacts. The data that we are processing consists of the archaeological shipwreck " Xlendi, Malta " , which was collected by photogrammtry and modeled by the Ar-penteur ontology. Following semantic web best practices, the produced CH dataset was published as linked open data (LOD).

The 21th century promises to be more volatile and creative than the previous centuries. In 2017 almost half of the planet’s inhabitants will have access to the internet and the majority of its youth will be literate. Although computers have not evolved through any groundbreaking innovation in the last decades, they have created opportunities for shared reflection that were unthinkable thirty years ago. As all sciences and fields of study, archaeology stands to gain a lot from this social revolution. This thus discusses some ideas, concepts and applications of computers in the archaeological academic culture, based on the current landscape and projections in the field of maritime archaeology.

In recent years, applications of Computer-Vision (multi-image) photogrammetry became popular in maritime archaeology.  This technology has been repeatedly tested in archaeological surveys and excavations in dry and submerged environments. Yet, there are still active discussions about the efficiency and accuracy of Computer-Vision (multi-image) photogrammetry models.

A team from the Nautical Archaeology Program at Texas A&M University developed a methodology to record and analyze underwater shipwreck sites with off-the-shelf software, including Computer-Vision (multi-image) photogrammetry. This methodology produced reliable archaeological data, based on 1:1 scale-constrained photogrammetry models, such as 2D site plans, hull lines, and timber catalogues.
This paper details a user-friendly methodology for underwater archaeological recording and explains step by step the tasks required to produce accurate 3D models, geo-referenced high-resolution photo mosaics, section profiles, and high-quality visual tour animations.

In this paper we present a photogrammetry-based approach for deep-sea underwater
surveys conducted from a submarine and guided by knowledge-representation combined with a
logical approach (ontology). Two major issues are discussed in this paper. The first concerns
deep-sea surveys using photogrammetry from a submarine. Here the goal was to obtain a set
of images that completely covered the selected site. Subsequently and based on these images,
a low-resolution 3D model is obtained in real-time, followed by a very high-resolution model
produced back in the laboratory. The second issue involves the extraction of known artefacts present
on the site. This aspect of the research is based on an a priori representation of the knowledge
involved using systematic reasoning. Two parallel processes were developed to represent the
photogrammetric process used for surveying as well as for identifying archaeological artefacts
visible on the sea floor. Mapping involved the use of the CIDOC-CRM system (International
Committee for Documentation (CIDOC)—Conceptual Reference Model)—This is a system that has
been previously utilised to in the heritage sector and is largely available to the established scientific
community. The proposed theoretical representation is based on procedural attachment; moreover, a
strong link is maintained between the ontological description of the modelled concepts and the Java
programming language which permitted 3D structure estimation and modelling based on a set of
oriented images. A very recently discovered shipwreck acted as a testing ground for this project; the
Xelendi Phoenician shipwreck, found off the Maltese coast, is probably the oldest known shipwreck
in the western Mediterranean. The approach presented in this paper was developed in the scope
of the GROPLAN project (Généralisation du Relevé, avec Ontologies et Photogrammétrie, pour
l'Archéologie Navale et Sous-marine). Financed by the French National Research Agency (ANR)
for four years, this project associates two French research laboratories, an industrial partner, the
University of Malta, and Texas A & M University.

Methods to record shipwreck sites have evolved considerably in the past two decades. Digital technology and marine robotics regularly present faster and more precise ways to excavate, clean, tag, and record ship remains, while computers simplify many of the steps involved in the reconstruction of ships from their archaeological remains. At the same time, the internet is creating opportunities to share primary data in real time and on a wide scale. This paper presents a methodology used by the authors to record and reconstruct the wooden structures of a 19th-century shipwreck in southern Brazil (Lagoa do Peixe site) and of a 16th-century shipwreck in Croatia (the Gnalić shipwreck).

One of the main goals of the Nautical Archaeology Digital Library
(NADL) is to assist nautical archaeologists in the reconstruction of ancient ships and the study of shipbuilding techniques. Ship reconstruction is a specialized task that requires supporting materials such as reference to fragments and timbers recovered from other excavations and consultation of shipbuilding treatises. The latter are manuscripts written in a variety of languages and spanning several centuries. Due to their diverse provenance,
technical content, and time of writing, shipbuilding treatises are complex written sources. In this paper we discuss a digital library approach to handle these manuscripts and their multilingual properties (often including unknown terms and concepts), and how scholars in different countries are collaborating in this endeavor. Our collection of treatises raises interesting challenges and provides a glimpse of the relationship between texts and illustrations, and their mapping to physical objects.

Este projecto, teve como objectivo proceder à reconstrução de uma nau quinhentista, com base em informação arqueológica e documental, e analisar as suas características físicas e o seu desempenho. Com base nas fontes iconográficas, documentos da época e nas peças encontradas no fundo do rio Tejo junto ao forte de São Julião da Barra (referentes a uma nau naufragada em 1606), é possível estabelecer configurações plausíveis para o desenho das formas do casco e aparelho destes navios, e testá-los por meio de processos científicos, em ambientes controlados.

The stability characteristics of 16th century ships are not known with certainty, but safety issues related to floatability, stability and overloading were a cause of concern at the time. The aim of the paper is to advance knowledge in this field by developing a set of loading conditions for a typical Portuguese ship of this epoch, for both the voyage from Lisbon to India and the return voyage. This allows testing the reconstruction of the presumable Nossa Senhora dos Mártires as well as to use this reconstruction to
bring a better understanding of safety and loading issues on the Portuguese East India route. Given the uncertainties about the loading conditions, several hypotheses are tested, varying the amount of ballast, the degree of overloading and the distribution of weights on board, and allowing the development of a range of plausible loading arrangements. The stability of the ship is then assessed using modern tools to develop the limit KG curve for compliance with a modern stability criterion applicable to large sailing vessels. The case study ship is a plausible reconstruction based on the analysis of nautical archaeological remains, contemporary documents and the use of modern naval architecture methods.

This article is part of a series of papers on the attempts to reconstruct and understand an early-17th-century Portuguese Indiaman based on the archaeological remains of the presumed Nossa Senhora dos Mártires, a Portuguese nau that sank at the mouth of the Tagus River, Portugal, in September 1606. With the help of 3-D computer software, the authors try to understand how the interior space of this ship was used and occupied, and propose a plausible size, weight, and configuration for the cargo storage, which will be tested in terms of the fully loaded ship’s intact stability. The result is intended as a theoretical model of a ca. 1600 Portuguese nau. Only further archaeological probing will tell whether it is an accurate model or not.

The Portuguese sailed yearly on the India Route during over two centuries, between the early XVI century and the XVIII century. Most ships employed in this route belonged to the Nau type and were among the largest and strongest ships of their time. Although extremely interesting, there is presently very little knowledge about the technical characteristics of these ships. The reason
is that they were built in a pre-industrial era when technical design and documentation procedures almost did not exist. The method that is presently being applied by the authors to investigate the technical characteristics of these ancient ships combines the analysis of archaeological remains, the interpretation of contemporary texts on shipbuilding and modern Naval Architecture
techniques.
The paper starts by describing the ship wreck discovered recently at the mouth of the Tagus River, known as the Pepper Wreck, which was identified as the Portuguese ship Nossa Senhora dos Mártires, lost in this place on its return voyage from Cochim, in India, on September 14, 1606. This is the first significant ship wreck of a Portuguese Nau comprehensively excavated and analyzed by Nautical Archeologists and in fact the resulting data made possible the study presented here. Based on the analysis of the archaeological remains and on contemporary texts, including Portuguese shipbuilding treatises, a reconstruction of the lines plan and rigging is proposed, as well as the lightweight and cargo distribution on board. The cargo spaces resulting from the reconstruction of the hull are evaluated using ancient tonnage measurement techniques and modern Naval Architecture
techniques to evaluate the cargo capacity of the ship. The intact floatability and stability of the ship are also investigated and compared with a modern stability criterion appropriate for large sailing vessels.

During the winter of 2013/14 a number of violent storms and related surges exposed a remarkable shipwreck site-tentatively dated to the early or mid-16th century-containing a timber assemblage, hundreds of pewter plates and other artefacts on Belinho beach, near Esposende in the north of Portugal. An international team was assembled including archaeologists from the Esposende city council and researchers from the ForSEAdiscovery Project. The objective of this project was to join a number of different experts and explore innovative methodologies to record and analyse ship timbers with forest management and timber supply networks in the Age of Discoveries.
A key recording strategy included the use of a Faro-Arm digitiser to record wood grain and timber conversion, together with photogrammetry, which was used to represent the timber surfaces. The compounded digital models were processed with Rhinoceros 3D modelling software. The collected data allowed researchers to model and develop reconstructed parent tree shapes from each ship timber, and try to better understand tree growth patterns, possible forest management activities, and timber selection for one of Iberia's major post-medieval industries: shipbuilding.
The Belinho 1 Project is an ongoing experiment where an array of techniques is being tested with the involvement of the local community, in order to help us understand the Iberian shipbuilding world, share our discoveries as widely as possible, and let the technologies utilised interact and invite new questions and ideas, and hopefully produce a methodology to identify tree selection methods, conversion techniques, as well as shipbuilding practices and philosophies.

Durante as fortes tempestades ocorridas no Inverno de 2013/4, violentas marés arremessaram um conjunto extraordinário de madeiras de navios bem como centenas de outros artefactos ao longo da praia de Belinho no norte de Portugal. Uma equipa de investigação internaci- onal, composta por arqueólogos do Concelho de Espo- sende, bem como de investigadores do projeto ForSEA- discovery, foi criada com o objetivo de estudar a coleção de madeiras e de artefactos arrojados, recorrendo a técnicas de registo digital e análise multidisciplinar. O projeto de investigação adotou uma metodologia que incluiu a representação tridimensional das madeiras em registo digital. A recolha de dados foi realizada com re- curso ao digitalizador 3D FARO-Arm que potencializou a obtenção de dados com elevado nível de detalhe da superfície das madeiras da embarcação. Esta abordagem proporcionou a criação de um modelo integral digital de cada um dos espécimes, que foi posteriormente proces- sado e analisado através do software Rhinoceros 3D. A informação recolhida permitiu aos investigadores envolvi- dos modelar e teorizar acerca das linhas originais do casco do navio, mas também sobre as árvores utilizadas na sua construção.O projeto ForSEAdiscovery tem como objetivo investigar a gestão das florestas dedicadas à construção naval ibérica entre os séculos XVI e XVIII. Neste âmbito a embarcação Belinho 1 representou um excelente candidato pelas suas características únicas. Por este motivo foi incluído como caso de estudo num projeto internacional e multidisciplinar, permitindo o desenvolvi- mento de metodologias de registo arqueológico e pela primeira vez em Portugal adotar-se o conceito de reconstrução do “navio” como uma floresta flutuante.

No Inverno de 2014 um importante conjunto de madeiras de cariz náutico foi sendo arrojado à costa a norte de Esposende, na praia de Belinho. Juntamente com as madeiras deram igualmente à costa artefactos metálicos diversos, concreções ferrosas e pelouros em pedra.
Madeiras e artefactos provinham indubitavelmente de uma mesma origem: um local de naufrágio ainda desconhecido mas certamente situado ou ao largo daquela praia ou nas suas imediações.
Como a natureza rochosa do fundo, a frequência da agitação marítima e a fraca visibilidade dificultavam a localização do suspeitado destroço, a salvaguarda do sítio limitou-se ao acautelamento das peças arrojadas, tarefa levada a cabo pelas arqueólogas da Divisão de Acção Cultural da Câmara Municipal de Esposende (CME), com o apoio total da autarquia.
Entre 2015 e 2017, sucessivas tempestades levaram a novos arrojamentos. Muitos deles ocorreram a desoras, sem a supervisão dos técnicos da CME ou dos achadores originais, concorrendo para a delapidação dos bens arqueológicos, quer sob efeito do mau tempo, quer efectivamente desaparecendo por serem levados por outros utentes da orla marítima.

ABSTRACT
In the winter of 2014, an important set of wood,
diverse metal artefacts, iron concretions and gunstones
washed ashore North of Esposende, at Belinho beach.
Between 2015 and 2017, a succession of storms resulted
in more wreckage being washed ashore.
In April and May 2017, both geophysical surveys carried
out off the coast and recognition diving made it possible to
identify an anchor, four bronze and iron cannons, related
wood, and several artefacts belonging to a shipwreck site.
This is probably one of the most important underwater

In the winter of 2014, an important set of wood, diverse metal artifacts, iron concretions and stone cannon shot washed ashore North of Esposende, at Belinho beach. Between 2015 and 2017, a succession of storms resulted in more wreckage being washed ashore.

In April and May 2017, both geophysical surveys carried out off the coast and recognition diving made it possible to identify an anchor, four bronze and iron cannons, related wood, and several artifacts belonging to a shipwreck site. This is probably one of the most important underwater archaeological sites to have ever been found in Portugal.

No Inverno de 2014, um importante conjunto de madeiras, artefactos metálicos diversos, concreções ferrosas e pelouros em pedra foi sendo arrojado à costa a Norte de Esposende, na praia de Belinho. Entre 2015 e 2017, sucessivas tempestades levaram a novos arrojamentos.
Em Abril e Maio de 2017, prospecções geofísicas realizadas ao largo da praia e mergulhos de reconhecimento permitiram identificar uma âncora, quatro bocas-de-fogo em bronze e em ferro, madeirame em conexão e vários artefactos em contexto de sítio de naufrágio. Provavelmente, estaremos na presença de um dos mais importantes sítios arqueológicos submersos até agora localizados em Portugal.

During the ferocious storms of 2013/4, violent waves threw up a remarkable set of ship timbers and hundreds of pewter plates onto the beach of Belinho in northern Portugal. An international investigative team was assembled jointly between archaeological experts from the Council of Esposende and the ForSeaDiscovery project whose objective it is to develop innovative timber and shipwreck recording and analysis methodologies as well as exploring historic timber supply and forest management in the Iberian Age of Discoveries. A key recording strategy included the usage of Faro Arm digital measuring technology, which allowed the detailed recording of individual diagnostic ship timbers and was complemented using photogrammetry. This allowed a complex model of each timber to be rendered in Rhino engineering 3D modelling software. Alongside a detailed timber record using photography, measurement and contract tracing, a comprehensive record of the assemblage was collated. This data is allowing investigators to model and reconstruct parent tree forms for each ship timber. In this way, we can say something about how trees were grown, managed and selected as part of a major Iberian shipbuilding industry. Project Belinho has contributed in many ways to the development of a 3D digital glossary and new methodologies for recording and interrogating ship timber assemblages. The reconstruction of the whole story of 'ship' as a " floating forest " is innovative in this regard. Equally, the wider international expert team is studying the ship's reconstruction and hull form, wood sciences including dendrochronology, DNA and isotopes, GIS mapping looking at trade routes.

During the ferocious winter storms of 2013 and 2014, over seventy ship timbers and numerous associated artefacts were washed from the sea onto the beach at Belinho. Thanks to effective collaboration between local inhabitants and the archaeologists of the City of Esposende, the timbers and artefacts were collected and placed into storage to allow more detailed study. This paper provides an overview of a programme of recording and sampling of the timber assemblage undertaken by a team from ForSEAdiscovery, a Marie Curie funded network, working in collaboration with local archaeologists through delivery of an international school of nautical and underwater archaeology in August 2015. The timbers were recorded using a range of techniques including traditional scale drawing, direct measurement and photography. For the first time in Portugal, selected timbers were recorded using a 3D contact digitizer as part of a program of research into development of techniques which facilitate reconstruction of the parent trees from which the timbers were cut, and provide a digital archive for future analysis and visualisation. Selected timbers were also sampled for dendrochronology and a range of wood science analyses as part of the ForSEAdiscovery program. Provisional interpretation of the ship timber assemblage will be presented and preliminary results of any completed analyses considered.

Situated on the southern coast of Portugal, the Arade River mouth has been visited and inhabited for over three millennia.
Dredging operations, in the first and last decades of the 20th century, brought up the importance of Arade’s cultural heritage
and triggered a large-scale project of study, survey, and archaeological excavation. This project is conducted by Centro Nacional de Arqueologia Náutica e Subaquática, the Portuguese agency for nautical archaeology, under the direction of Francisco Alves, and with the support of both local and state authorities. This paper is a preliminary assessment of the finds made so far.

During more than one year (2016-2017) public works at Campo das Cebolas, in downtown Lisbon, have exposed archaeological complexes related with his waterfront. This central node of the city and harbor was essential since the Portuguese maritime expansion which spans a period of 500 years, gathering mercantile and daily life activities, buildings, small shipyards, and ships connecting water and land.

This paper presents a summary of the finds and a comment of the interest of this excavation, carried out by the municipality of Lisbon (EMEL), due to the construction of an underground parking area and urban rehabilitation, with a big team of more than 50 archaeologists, conservative restorers and technicians of 3D digital records.

The Ribadeo shipwreck, identified as the San Giacomo di Galizia, lost in 1597 at Ribadeo, Galicia, Spain, is a unique example of a late 16th century Spanish warship. Brought to Ribadeo in the winter of 1597, this ship was salvaged, all the crew saved, and its remains abandoned. It was found in November 2011 during dredging operations, and it has been studied since. Excavated slowly at the pace allowed by the conservation budget, this site is revealing its secrets as the excavation progresses. This paper is an introduction to the ship’s history and a first report on the archaeological excavation of its hull remains.

The report aims at presenting the current knowledge regarding the Utrecht / N. S. do Rosário shipwreck battle site off Itaparica, Bahia, Brazil. This research effort is part of an ongoing international project which seeks to document and assess the significance of shipwreck sites from the colonial period in Brazil, previously looted by treasure hunters or salvaged during Brazilian Navy operations in the late 1970’s and 1980’s. This research was carried out as part of the Maritime Program of the Mutual Heritage Program in the Netherlands, and within the framework of the Memorandum of Understanding concerning Mutual Heritage, as signed by Brazil and the Netherlands in 2008 (Cooperação no Campo do Patrimônio Cultural Comum) after an invitation of the Dutch Cultural Heritage Agency (Rijksdienst voor het Cultureel Erfgoed) to the Brazilian National Institute of Historic and Artistic Sites (Instituto do Patrimônio Histórico e Artístico Nacional – IPHAN). The project also includes the support and cooperation between researchers and professors from the the Nautical Archaeology Program at Texas A&M University, USA, and Federal University of Sergipe/UFS, Brazil. Recent research efforts have been oriented to: 1) study the site formation processes and reconstruct scope and chronology of the interventions there carried out, 2) inventory and collect publications, site plans, photos, videos, excavation logs and remaining artifact collections related to the site, and 3) to review the historical and nautical backgrounds behind the naval engagement between the Portuguese and Dutch fleets off Itaparica in September 28, 1648. The present report and its accompanying catalogue CD were prepared in order to share the project`s preliminary results and setup a baseline for future research.

The remains of a Roman barge were found in 1981 in the River Stella, Udine, Italy. Its cargo consisted mainly of roof tiles. It was excavated in 1998 and 1999, and detailed recording of the hull, and a second wooden structure, was achieved in 2011. A spread of material upstream of the wreck has been investigated 2012–2015. The barge was originally dated to the first quarter of the 1st century AD by the in situ cargo. This article describes the bottom-based sewn-plank hull construction and examines it in the light of local boatbuilding traditions. The second wooden structure is also described, along with recent finds and new dating evidence from the dispersed material. The Stella 1 excavation was part of the Anaxum Project, a wider study of the Stella River's cultural landscape through time.

The waters of Puerto Rico harbour the remains of thousands of years of human occupation. The island played a key role in the
first decades of European exploration of the New World, and its coasts and estuaries have preserved an extensive record of the
island’s maritime history, before and after the arrival of the Europeans. The objective of this project is to study Puerto Rico’s
seafaring history through the investigation of its submerged cultural heritage, with a particular focus on the history of European
shipbuilding. In 2008 the authors started with survey on the north coast.

"Although officially registered in 1967, the Gnalić site was discovered in the early 1960s and in the interim much of the material found its way into private collections in Belgium. The first three rescue campaigns were organized in 1967 and 1968, while the next two followed in 1972 and 1973. A short excavation campaign took place in 1996 in order to renew the excavation and initiate protective measures of the wreck site. Due to administrative complications the attempt remained without success.
Forty five years after the first campaign, in the summer of 2012, a joint team from the University of Zadar and Texas A&M University carried out a testing excavation season on the Gnalić shipwreck site, identified as the large merchantman Gagliana grossa, lost in 1583 on its way from Venice to Constantinople.
Thanks to the remarkable results of the archaeological and historical research, the support of the local government and the involvement of many Croatian and foreign institutions, the project entitled “The Shipwreck of Gnalić – Mirror of Renaissance Europe” was launched, encompassing the continuation of research into the shipwreck itself and its natural, cultural and historical context; the improvement of the condition of finds removed during earlier research and the formation of an education/presentation/research centre."

Biology, subsistence, evolution, perception, adaptation, ecology, social organization, power structures, production processes and chains, mobility, ideology, freedom, ideology, death and religion, our relationship with objects (man-made and not). Maritime archaeology is a subdiscipline of archaeology, but it is becoming an occupation for polymaths.
The present discussions of theory in archaeology urge us to consider how gender, ethnicity, genetics, phenotypes, historical relations of dominance, or ethnic hatreds influence our interpretations of the past.

Abstract: The location in Ribadeo (Lugo, Spain) of the wreck of a war galleon in the Spanish kingdom of Naples, Almiranta of a squad on service of King Philip II, is an unique opportunity to know the characteristics of this kind of ships. Her historical and archaeological study in archives and underwater allows us an integral approach to her past and actual reality. Her conservation goes through the study in a very dynamic environment that faces powerful forces that compromise its integrity. Identifying both natural and anthropic risks is a first step to ensure her conservation. The
establishment of physical measures applied on this wreck for the first time also represents an advance in the conservation of submerged sites.

This course is an introduction to the basic technical skills required for recording, representing and interpreting ship archaeological remains. Students are expected to develop a practical approach to the conceptualization and design of a ship. This course is divided in three parts: recording a shipwreck, reconstructing a ship from its archaeological remains, and producing a comprehensive ship project. Upon completion of ANTH616 students are expected to be familiar with: a) the particular vocabulary of shipbuilding; b) the basic rules and methods to map an archaeological site; c) the basic rules and methods to record hull remains: how to quantify and represent 3D curves on paper and how to produce a clear and comprehensive set of documents with all relevant records pertaining to a particular set of ship's hull remains; d) the basic principles of ship construction, in terms of the structural components of a ship and its construction sequence; e) the process of designing a ship's hull in the three standard views of the so-called "lines drawings" of a vessel; f) the basic rules to reconstruct an archaeologically excavated ship's hull and formulate an educated guess about the vessel's probable size, shape and structural composition; g) the standards for graphic representation of ship's hulls and their components; h) the basic rules of hull analysis.

Shipwreck stories have the potential to attract the attention of a wide public in different ways.

During the winter of 2013/14 a number of violent storms and related surges exposed a remarkable shipwreck site—tentatively dated to the early or mid-16th century—containing a timber assemblage, hundreds of pewter plates and other artefacts on Belinho beach, near Esposende in the north of Portugal. An international team was assembled including archaeologists from the Esposende city council and researchers from the ForSEAdiscovery Project. The objective of this project was to join a number of different experts and explore innovative methodologies to record and analyse ship timbers with forest management and timber supply networks in the Age of Discoveries. A key recording strategy included the use of a Faro-Arm digitiser to record wood grain and timber conversion, together with photogrammetry, which was used to represent the timber surfaces. The compounded digital models were processed with Rhinoceros 3D modelling software. The collected data allowed researchers to model and develop r...

Data sharing is a fundamental process for the advancement of both natural and social sciences. Starting from the idea that computers and the internet have drastically changed the world in the last decades, this paper advocates for the creation of a space where archaeologists from around the world can share information about maritime history and exchange data with colleagues. Following the principles of open access, we argue that the publication of raw data is necessary and significant for the development and democratization of the discipline. Below, we explain the fundamental aspects of the Nautical Archaeology Digital Library (NADL, https://nadl.tamu.edu/) and its efforts to standardize information collection for shipwrecks and related sites, so that scholars can create a community to disseminate both raw data and complete information in the field of maritime archaeology. To achieve this, our purpose is to contribute towards a common-ground methodology and terminology that promotes an intelligible dialogue within the global community of nautical archaeologists. This paper addresses some considerations on terminology and systematization in scientific disciplines and discusses the theoretical and methodological issues linked to the process of creating a template for recording shipwrecks. Furthermore, it discusses some of the problems related to the standardization of description processes and the necessity to create a flexible system that accounts for the diversity of the data. The third section discusses how science is greatly enhanced by the publication of information in open access platforms.

Almost three decades ago J. Richard Steffy (in: Tzalas (ed) Tropis II, pro- ceedings of the 2nd international symposium on ship construction in antiquity. Athens, pp 315–320, 1990, in: Tzalas (ed) Tropis III, proceedings of the 3rd international sym- posium on ship construction in antiquity. Athens, pp 417–428, 1995) voiced the need to standardize the recording and publication of shipwrecks. Cluster analysis of construction features is difficult if archaeologists record different and non-overlapping features. This paper discusses the necessity to standardize the recording and publishing of a set of consistent and compatible basic construction features when archaeologists assess, survey, or excavate wooden shipwrecks and proposes a methodology for the recording of wooden hulls. It also emphasizes the urgency of a wide and complete sharing of archaeological information in maritime archaeology.

Una de las cuestiones más difícil de determinar durante el estudio de los restos arqueológicos de un pecio es la referida a su tonelaje original. Esta comunicación presenta los resultados preliminares del estudio realizado en el Ship Lab del Nautical Archaelogy Program (Texas A&M) acerca de los métodos de arqueamiento utilizados en España desde finales del siglo XVI a principios del siglo XVII. El valor del arqueamiento de un buque era de gran importancia ya su tonelaje determinaba sus características constructivas y el valor de la compensación económica del embargo, el sistema mediante el cual el monarca requisaba buques para sus necesidades navales. De la misma forma, el valor del arqueamiento de los buques también se encontraba en la base del sistema impositivo de la monarquía en relación al comercio ultramarino. El presente estudio pretende determinar si es posible establecer una correlación entre las diferentes formulas de arqueamiento proporcionadas por los diversos tratados navales de inicios de la Edad Moderna y los escasos restos materiales de pecios ibéricos excavados hasta la fecha.
