The Severne Moto is the easiest way to go as fast as possible on a windsurf board.  This 2-cam "Freerace" sail is lighter than many no-cam freeride sails both in actual weight and certainly on the water.  Top speeds achieved by PWA pros on the Moto are on par with their PWA level race sails.  The cams on the Moto rotate effortlessly.  Overall, the Moto has an incredible wind range and when paired with a board like the Severne Fox, you're going to be flying past your friends!
