Bateaux were a key utility craft in military operations in the colonies of North America. Their size, durability, and ease of construction made them ideal for moving troops and supplies over the lakes and rivers of New England and New France. The purpose of this presentation is to provide a construction analysis of the remains of some British colonial bateaux recovered from Lake George and place them in their historical context. The craft were built from a very simple design, and were hastily...

The paper compares the relative speeds of British and Dutch vessels from 1750 to 1850, using data from the CLIWOC (Climatological Database of the World’s Oceans) database. Originally compiled to extend the available information on weather patterns back into the ‘pre-instrument’ period, the database also includes information on the ships that recorded the data. Average daily speeds and maximum recorded speeds were analyzed for 250 unique Dutch ships and 485 unique British ships in order to...

The warships that took part in the Battle of the Egadi Islands (241 BC) were highly specialized and advanced ramming warships, yet our understanding of these vessels is limited to vague historical accounts, artistic depictions, and sparse archaeological evidence.  The Egadi Islands Survey Project, a joint project of the Soprintendenza del Mare - Sicily and RPM Nautical Foundation aims to survey and excavate the battle site in order to understand the events of the Egadi Islands Battle. This study...

In 2014 the excavation and recording of the Gnalic shipwreck hull remains, using photogammetry and integrating standard surveying techniques within a GIS environment, continued during eight weeks. This paper describes the 2014 field season at Gnalic and presents the latest developments in the hull recording.

Infrared photography has been a useful tool for archaeologists in observing unseen macrofeatures, particularly with aerial photography and sattelite imaging. However, the infrared spectrum's potential usefullness to archaeologists extends beyond the macroscale. Recovery of trace details, writing, corrosion patterns, and other elements invisible to the human eye and visible light protography may be possible through the use of infrared photography. Using a converted Canon 20D digital Single-Lens...

This paper presents the latest results of the ongoing historical and archaeological research on Gagliana grossa, a merchantman built in Venice in 1569.  It sunk while travelling from Venice to Constantinople, in November of 1583, near the small island of Gnalic, not far away from Biograd na moru, in today’s Croatia.

The Highbourne Cay Shipwreck, found in the Exumas, Bahamas, is the most intact example of a ‘Ship of Discovery’ in the world. The identity and purpose are still unknown, yet a recent, non-intrusive visit to the site recorded no obvious signs of damage to the ballast mound. Because the site has been disturbed and re-covered on two documented occasions, valuable reflexive questions can be asked decades later regarding the effectiveness of conservation in situ. Soon, the Bahamas will be lifting...

Steamboat construction of the early nineteenth century remains largely forgotten and unstudied.  Historical records provide little detail to how construction techniques were evolving in this experimental phase of steam-powered vessels.  A survey of Lake Champlain’s Shelburne Shipyard revealed the remains of four nineteenth-century steamboats, three of which were built prior to 1840.  The four hulls were recorded for comparative study during a field school which took place in the month of June,...

This paper briefly examines the structure and construction of the slave ships in the United States and England and looks at how slave ships are different in structure and function from other merchant vessels. By examining them as special purpose ships, trends in structure and construction become apparent and prove to be unique to slave ships. The material culture found in the archaeological record that could identify a ship as having participated in the slave trade will also be examined. The...

The survival of late medieval Mediterranean techniques to conceive and build ships and boats in Brazil was noted by John Patrick Sarsfield in the 1980s, but his study of the Valença shipwrights was interrupted by his tragic death in 1990.  This paper is a contribution to the understanding of these shipbuilding techniques, which are still widely used in the region, from Valença to the Baía de Todos os Santos area.
