The size of wooden components in relation to the tonnage of Greek and Roman ships

This article focuses on the size of tonnage as an impact on the size of wooden components in a ship. It is based on a list of 66 tonnages, elaborated via a methodology employing three methods to determine tonnage (reconstruction of the hull lines, the tonnage formula, and the weight of the cargo). This list notes the thickness of the planking and of the moulded side of the frames. However, the article also explores further factors that are involved, particularly the evo­lution of the architectural type.
