[0050] overview

[0051] figure 1 A suspension system 1 for a sailboat 2 is shown. The suspension system 1 comprises a mast 3 extending substantially perpendicularly from the hull 4 of the sailboat 2 . The boom 5 extends horizontally to the mast 3 and, in use, a sail 11 is fitted to the mast 3 and the boom 5 .

[0052] A vang tube 7 extends between the mast 3 and the boom 5 to counter the relative force and / or moment of the boom 5 towards the mast 3 . That is, the tension tube 7 provides a downward force to the boom 5 which helps to maintain the shape of the sail 11 . The cable tube 7 is substantially arc-shaped, with its convex surface facing the intersection 9 of the boom 5 and the mast 3 .

[0053] In use, at least a portion of the sail 11 is supported by the tensioning tube 7 such that the tensioning tube 7 assists the transition from the straight foot 15 of the sail near the boom 5 to the smooth curve of the sail 11 . Furthermore, the curved guying tube 7 may also ...

Abstract

The invention discloses a suspension system (1) for a sailboat, comprising: a mast (3) extending substantially vertically from the hull; a suspender (5) extending approximately horizontally from the mast (3); between the rods to counteract the relative force and / or moment of the boom (5) towards the mast (3), the tensioning tube (7) is characterized in that said tensioning tube (7) is substantially arc-shaped , and the convex side of the arc-shaped cable tube (7) faces the intersection (9) of the boom (5) and the mast (3), and wherein the cable tube (7) is in the above the rod (5). A connection (301) for transmitting a first force from a spar wing (307) to a mast (3) of a sailboat, said connection comprising: a connection base (303) having a key (305) to housed in a keyway (306) that is part of the sail track (107) of the mast (3); a mount (309) that houses said spar wing (307), wherein, from said spar wing ( The first force (35) of 307) is transmitted to the connection base (303) through the mounting part (309); and the limiter (311) against the first component force (37) acting on the connection base (303) , where the first force component (37) is the component of the first force (35) transmitted from the spar wing (307), which is in a direction parallel to the keyway (306).

Description

technical field [0001] The invention relates to a suspension system for a sailboat. Background technique [0002] The suspension system is an important component in propelling a sailboat. Sailing boats are often used for sporting purposes, and a small increase in performance is crucial to provide a competitive advantage to win races. [0003] In some sailboats, boom tensioning is used to provide a downward force on the boom to assist in maintaining the shape of the sail. Boom tensioning cables may include rigid straight tensioning tubing (eg, as in a "49er" sailboat), a piston system, a pulley system, or a combination thereof. These components may add weight and bulk to the sailboat. [0004] Competitive sailing can be competitive and highly stressful, and the ease of use of sailing components can give a sailor a competitive advantage. Safety is another important factor and may require at least part of the rigging to be easily foldable in high winds. In addition, compon...
