Abstract
A sail body comprises sail body material with reinforcement stitching along expected load lines. Optionally, the sail body may be a molded, three-dimensional sail body. At least half of the reinforcement stitching may extend along at least half of the lengths of the expected load lines. The reinforcement stitching may also comprise a combination of stretch-resistant and controlled-stretch stitching styles, the combination of stitching styles may further comprise a length of stretch-resistant stitching followed by or preceded by a length of controlled-stretch stitching. Optionally, the sail body material may be molded to create a three-dimensional, molded sail body. The molding step may be carried out before the reinforcement stitching is applied to the sail body material.
