Sail for watercraft, in particular sailboards

摘要

In the case of a sail for water vehicles, in particular sailboards, a highly swept delta-shaped surface 8 which merges with the actual sail surface 2 without forming a slot is mounted in front of the mast 1 approximately at the level of the boom 7. As a result, additional propulsion is generated at the sail by the formation of so-called leading-edge vortices. <IMAGE>
