A rigid propulsion wing for a moving vehicle, including at least one first section and one second section, a first end and a second end each including attachment means for reversibly connecting to said moving vehicle, said first section and said second section being movable with respect to each other by means of articulating means such that said propulsion wing assumes, and moves from, at least a first deployed position to a second deployed position, and vice versa, in which deployed positions said first and second sections are arranged, substantially vertically, in the extension of each other, and in which said first end, or respectively said second end, are reversibly connected to said moving vehicle by means of the attachment means thereof.

A propulsion system for a seagoing vessel includes a rotatable frame and either (a) at least two masts coupled to the frame and each having a sail and a boom, or (b) at least two blades coupled to the frame. The rotatable frame and either the rotatable boom or at least two blades may be locked in position in a locked mode and unlocked and freely rotatable in an unlocked mode. A control system that is in communication in communication with a frame lock and either a boom lock or a blade lock and may be configured to determine when the vertical axis wind turbine should be in either the locked mode or the unlocked mode based on the direction of the wind and a direction that the seagoing vessel is traveling.

A vessel is provided with a mast, sail, and halyard for hoisting the sail. The sail includes dollies configured to be movable along the mast. The mast includes a guide member, the guide dollies configured to cooperate with said guide member, wherein the sail includes rigid panels, articulated two by two; the mast is equipped with a transit part positioned at the end of the guide member, which has a flared lower portion and is open at its opposite ends, wherein during hoisting of the sail, each dolly is received in the transit part and is guided along to leave it through its upper opening and cooperate with the guide member, while during its lowering, each dolly is disengaged from the guide member, is received in the transit part, moves along it, and escapes from it by following the movement of the portion of the sail with which it is integral.

A shipping container includes a container configured to be secured onto a vessel or a vehicle. The shipping container further includes at least one wingsail stored in the container and configured to be unfolded to deploy from the container and folded to be stowed in the container,

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.

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 three sides, namely two longitudinal sides respectively called luff and leach, as well as a lower transverse side called foot consisting of an assembly of panels having transverse edges parallel to the foot and longitudinal edges parallel to the luff and the leach, each panel being hinged to the adjoining panel around an axis parallel to the foot. Each of the panels includes reinforcing elements distributed into the two following groups: (a) a first group in which they extend parallel and in proximity to said transverse edges, and (b) a second group in which they extend parallel and in proximity to the longitudinal edges of the panel. They are connected two by two by connection parts in the continuation of the reinforcing elements of the second group, so that the forces assumed by the reinforcing elements are transmitted longitudinally from one panel to another.

The invention relates to a wing type rigid sail fragmented into independent segments, where general principle involves diving the rigid sail into different segments that can position themselves independently from neighboring segments, depending on the wind received, with the profile of the sail controlled following two independent but complementary methods, where the segments at the front of the sail are linked together by their front flap, through a process that allows adjusting their relative freedom, playing on the angle that each segment can take compared to neighboring segments, and on the back of the sail sheet, the rope allowing sail adjustment links each segment by its back flap, top to bottom, allowing for adjustment of the opening up of the sail while keeping the desired flexibility of the sail.
