Abstract: The disclosure concerns a wind propulsion system 4 comprising a wind engagement unit 6, a first hydraulic actuator 8 arranged for generating a first tilt force for tilting the wind engagement unit, and a main hydraulic control arrangement 10 for controlling the first hydraulic actuator. A bypass arrangement 30 is connected to a second pressure chamber 28 of the actuator 8. The bypass arrangement is separate from the main hydraulic control arrangement. The wind propulsion system is configured for tilting of the wind engagement unit utilising a second tilt force which is generated independently of the main hydraulic control arrangement. The bypass arrangement 30 is configured for conducting hydraulic fluid from the second pressure chamber 28 when tilting the wind engagement unit utilising the second tilt force.

Abstract: A vessel mast 101 has a tube 103 which can be secured with an open lower end 103A to a deck 201 of a vessel. In the tube 103 there are two cylinders 107 and 111 with movable pistons 109 and 113 therein to which piston rods 108 and 110 are attached, and to which piston rods sails are attached. The cylinders keep the sails taut and dampen forces due to gusts of wind on the sails. In the tube 103 is also a pressure cylinder 115 and a pressure piston 117 movable therein with a pressure piston rod 118 attached thereto, as well as a securing device 119 for securing the vessel mast 101 to the deck 201. The pressure piston rod 118 is coupled to a part of the securing device 119 to tighten the locking device without play.

Abstract: Maritime drone (1) comprising a hull (2) provided with an upper face (3) and a lower face (4), a centerboard (5) extending projecting from the lower face (4) of the hull (2) in order to give sailing/navigation stability to the maritime drone (1) and at least one wing sail (6). The wing sail (6) comprises a mast (7) connected to the hull (2) and a wing profile (8) connected to the mast (7) and it is suitable to intercept the wind in order to move the maritime drone (1). The centerboard (5) internally defines a containment volume (9) for the wing sail (6), which is movable between an operative position, in which it extends at least partially above the upper face (3) of the hull (2), and an inoperative position, in which it is at least partially housed in the containment volume (9) of the centerboard (5).

Abstract: The present invention relates to a rig 2 for a nautical means comprising:
- a reference plane P1 intended to coincide with a symmetry plane extending in longitudinal and vertical direction of the hull 6 of the nautical means;
- at least one wing 4;
- at least one rigid support 3 capable of supporting said wing 4 and transmitting a propulsive thrust to the hull 6 of the nautical means given by the aerodynamic lift generated by the wing 4 when it takes wind;
- the wing 4 comprising a first and a second main face opposite to each other,
- the rigid support 3 being capable of supporting the wing 4 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 P1 plane and in a second operating configuration in which said main portion is facing the opposite side of the reference plane P1;
the rigid support 3 comprising a wing sliding path 18 for switching from the first to the second operating position and vice versa.-

Abstract: The present invention relates to a boat comprising at least one hull (2) and at least one rig (5), where said rig comprises at least one sail (10) fastened slidingly to an overturning guide (35), where the overturning guide defines a sliding path (S) between two operating positions that are specular between them, said sail has two ends (45) that are opposite in the sliding direction (S) and specular, characterized in that said rig comprises:
• a sail manoeuvring system (50) comprising:
- a pair of rigid elements (48), hereinafter referred to as boom/vang elements, placed at the specular ends (45) and sliding integrally with the sail (10) with respect to the overturning guide (35);
- one or more halyards (49) connected to the rigid elements (48) to pull them in opposite directions so as to adjust the tension of the sail between them, as well as in order to be able to make it slide along the overturning guide (35) alternately in one direction or the other,
- the rigid elements (48) are fastened with respect to the overturning guide (35) so as not to tilt in the sliding direction (S). -
