ABSTRACT:
The present sailboat sail has extremely high aerodynamic efficiency. The sail has a bifurcated forward edge, the forward ends (17A) of each of which is carried by a footing rope (45) in a track of a vertical stay (22); a fairing (44) is arranged to wrap around the leading edge of a mast (3), and the fairing has a pair of trailing edges (44A), each of which has a footing rope also disposed to be connected to said vertical stays (22); the stays (22) can be separated by a spacer (42) to control the aerodynamic disposition of the trailing edges (44A) of the fairing (44) and the leading edges (17A) of the bifurcated portion of the sail; an enlargement member (46) may be disposed between the inside of the leading edge of the fairing and the outside of the leading edge of the mast further to improve the aerodynamic disposition of the fairing and sail.
