The hull of a boat consists of an internal network of frames that extend from side to side (transverse) and that run the length of the boat (longitudinal), covered by an outer shell plating, usually made of fiberglass or metal.
The forward (leading) edge of the sail is called the luff, which, in a mainsail, is parallel to the mast. The aft (back) edge of a sail is called the leech (also spelled leach), which is opposite the luff, and forms the hypotenuse of the triangle.
