Shipbuilding: Bow and Stern Diagrams (p. 139b)


Shipbuilding: Bow and Stern Diagrams (p. 139b)


The shapes of most of a galley's frames were determined by proportion, but the geometry did not cover the shape of the bow or stern. These were determined in the yard, using string to get the proper curve. This drawing was intended to illustrate part of the process. The top diagram provides dimensions relating to the shape of the stempost; the bottom diagram, dimensions relating to the stern.
