ABSTRACT:
The sail is formed by a structure of stiffening elements comprising ribs r over which a sail-cloth zd is tightened to constitute a substantially stiff wing-like sail. The ribs r and girders l give the sail the correct profile and shape. The symmetrical sail is arranged to rotate and be mounted on top of the mast m on which it is able to hinge. The mast m is secured to the sailing-apparatus zt and able to hinge in one or more directions. The steering and control are done by exercising a moment around the centerpoint of the windforces by the sailor with the aid of handles or bows b. The mast m can be omitted and its functions fulfilled by the sailor, except when steering takes place with the aid of sheets. The sail can be composed of more than one profile and also be equipped with tails and fins. One variation has an adjustable angle between sail and mast m that can be locked in a chosen position. Another variation has a sail to mast connection sliding along the sail that can be locked in a chosen position.
