A wind-propelled vessel is described herein. The vessel includes at least one hull and at least one set of paired masts. Each paired mast of the at least one set of paired masts has a first mast located to one side of the vessel and a second mast located on the opposite side of the vessel. Also, each mast of the at least one set of paired masts has a spar located at or near the top of the mast. Moreover, each one of the spar located at or near the top of the mast extends inwards towards a center plane of the vessel, and an inward end of the spar is connected by a connector to another inward end of another one of the each one of the spar located at or near the top of the mast. In accordance with the illustrative examples provided herein, the connector imparts a dynamic force upon connected spars that responsively pulls the connected ones of the inward ends of the spars to their nearest position when tops of the masts to which the spars are fixably attached move away from a relative nearest position to a paired one of one set of paired masts.

A sailing boat includes at least one mast with at least one first and one second section projecting upwards with respect to the hull and arranged facing each other in the orthogonal direction to the advancement direction for supporting a mainsail in two mutually specular and alternative operating positions, where the sections are connected and spaced out from each other by at least one overturning section of the mainsail placed at the top of them to allow the passage from one specular position to the other. The three sections of mast define for that purpose a first sliding guide for the whole mainsail that extends substantially along the whole extension length of the mast and the mast includes a second sliding guide positioned substantially at the top thereof and placed aft with respect to the overturning section.

A rig for a nautical craft includes a reference plane intended to coincide with a symmetry plane extending in longitudinal and vertical direction of the hull of the nautical craft; —at least one wing; —at least one rigid support capable of supporting the wing and transmitting a propulsive thrust to the hull of the nautical craft given by the aerodynamic lift generated by the wing when it takes wind. The wing includes a first and a second main face opposite to each other, the rigid support being capable of supporting the wing at least in a first operating configuration in which at least a main portion of the first or second face is facing a first side of the reference plane and in a second operating configuration in which the main portion is facing the opposite side of the reference plane; the rigid support includes a wing sliding path for switching from the first to the second operating position and vice versa.

A trimaran which includes a self-righting structure positioned near the stern that substantially raises the center of buoyancy. The trimarans two peripheral hulls are shorter than the main hull and positioned near the one end to create an unstable inverted environment wherein when inverted the vessel rests primarily on the self-righting structure and an end of the main hull, substantially raising the center of gravity and creating an unstable configuration. This causes a pitch or roll about the vessel's longitudinal axis, which continues until the vessel has returned to its more stable upright position resting on three hulls.

The present invention relates to a rig (2) for a nautical means comprising: —a reference plane intended to coincide with a symmetry plane extending in longitudinal and vertical direction of the hull of the nautical means; —at least one wing; —at least one rigid support capable of supporting said wing and transmitting a propulsive thrust to the hull of the nautical means given by the aerodynamic lift generated by the wing when it takes wind; —the wing comprising a first and a second main face opposite to each other, —the rigid support being capable of supporting the wing at least in a first operating configuration in which at least a main portion of the first or second face is facing a first side of the reference plane and in a second operating configuration in which said main portion is facing the opposite side of the reference plane; —the rigid support comprising a wing sliding path for switching from the first to the second operating position and vice versa.

A sail includes at least two layers (36, 37) arranged side by side to form an aerodynamic profile. The wing includes at least one profiling device adapted to modify the aerodynamic profile.

A sailing boat includes at least one mast with at least one first and one second section projecting upwards with respect to the hull and arranged facing each other in the orthogonal direction to the advancement direction for supporting a mainsail in two mutually specular and alternative operating positions, where the sections are connected and spaced out from each other by at least one overturning section of the mainsail placed at the top of them to allow the passage from one specular position to the other. The three sections of mast define for that purpose a first sliding guide for the whole mainsail that extends substantially along the whole extension length of the mast and the mast includes a second sliding guide positioned substantially at the top thereof and placed aft with respect to the overturning section.

A trimaran which includes a self-righting structure positioned near the stern that substantially raises the center of buoyancy. The trimarans two peripheral hulls are shorter than the main hull and positioned near the one end to create an unstable inverted environment wherein when inverted the vessel rests primarily on the self-righting structure and an end of the main hull, substantially raising the center of gravity and creating an unstable configuration. This causes a pitch or roll about the vessel's longitudinal axis, which continues until the vessel has returned to its more stable upright position resting on three hulls.
