The Lines Plan is the most basic technical drawing associated with a vessel. It is used to describe the shape of the boat in three perspectives: Profile, Body, and Plan. The buttock lines describe the profile, the sections describe the body shape (fore and aft), and the water lines describe the shape in plan view.
The Structural Plan shows the framing for the hull and deck. It illustrates the location of frames, bulkheads, beams and blocking. This blueprint is the main tool used by the builders to size and locate the structural elements of the vessel. Fastener size and location is another key piece of information given in this plan.
