<p>A sail system comprising a substantially isosceles-triangle-shaped sail with two booms and an arc-shaped element. The two booms are arranged along substantially equal sides of the sail and articulated to one another with a joint that defines a vertex of the triangle. The arc-shaped element is coupled to a deck of a boat for pivoting about a transverse axis between a raised position and a lowered position on the deck. Each boom has a coupling element on the arc-shaped element, the coupling element being slidable both along the arc-shaped element and along the respective boom.</p> |
