Early shipbuilding methods and hull form

The earliest boat designs probably existed in builders' minds before writing materials made formal plans practical. By the Roman period, shipbuilders were using more deliberate design methods. Shell-first construction joined smooth carvel planking with mortise-and-tenon joints, producing strong hulls suited to demanding uses such as ramming. The wreck evidence places that tradition well before its later Greek, Roman, and Carthaginian use. Lapstrake, or clinker, construction overlapped planks to create a lighter, faster, and more quickly built hull, with different strength and rigging limits. A ship's appearance and performance grew directly from the skills, time, and resources available to its builders.
