Please Note: Most of our sail dimensions are based on class rules, designer blueprints, or measurements of sails. These dimensions are intended as starting points only. Sailboats are not all uniform, even from the same designer. We recommend carefully measuring your boat if you are uncertain about dimensions.

All dimensions are intended to be maximum and smaller sails are not wrong.

We've limited our listing to the sails most commonly used, but these are not the only ones appropriate for a given boat.
