A sailboat mast is composed of two portions, a forward portion supported on the hull by standing rigging and having a concave aft side, and an aft portion, which may be of circular cross-section, supported close to and in line with the forward portion at both ends, the top support, however permitting the top of the aft portion of the mast to be bent away from the forward portion in order to affect the shape of the sail. The main sail is carried by the aft portion of the mast in such a way that when working in any kind of a crosswind, it extends away from the mast in a substantially tangential direction, on the lee side.
