A high efficiency aerodynamic sail system for boats comprises a triangular fabric sail pivotally suspended at its head from the apex of a tripod mast structure such that air impinging upon the luff of the sail is free from the turbulent wake of any upwind structure. The foot of the sail is attached only at its tack and clew ends to opposite ends of a spar which is pivotally attached at its center to a short stub mast centrally positioned in respect to the tripod mast. The sail luff and leech side deflections are caused to be identical by cables to provid...
A high efficiency aerodynamic sail system, comprising: a. a sail having a luff, a leech, a head and a foot, said sail having a center of area at, or below, mid-height, b. means for supporting said sail, said supporting means being adapted to suspend said sail from every corner, said supporting means being adapted for mounting on a sailing craft, said supporting means including means to adjust the angle between said sail and said sailing craft while sailing, and to maintain said angle independently of the strength of the incident wind, c. means for causin...
