A sailing vessel is disclosed in which a mast is pivotally connected to the hull at the lower end thereof and an athwartship structure is provided in the form of a support rigidly mounted to the hull and transverse thereto to guide the mast athwartship. The mast may be held in an upstanding attitute or an angular attitude by mechanical devices of lines or other adjusting means. Bringing the mast and the sail mounted thereon to a vertical attitude reduces the heeling moment that affects the vessel.
