Abstract
A single or multi-hulled sailing craft has a stub mast,upstanding from the hull. A sail,has a luff edge,secured to a luff boom,and a foot edge,secured to a foot boom,which is connected to the lower end of the luff boom. Part way along the luff boom,a pivotal fitting,connects the luff boom to the stub mast,and a rigid swing boom,is pivotally connected between the foot boom,and the hull or the stub mast. The fitting,can be moved up and down the stub mast,by means of a tilt sheet. The swing boom can be connected to a carriage which moves transversely of the hull. The sail is self-tacking and its position is positively controlled to prevent collision of the sail with the stub mast.
