摘要:
The invention concerns an apparatus for adjusting the surface of at least one sail (2, 3) exposed to the wind in a boat (1). The apparatus comprises one or more detectors (R) of at least one quantity from the direction of the wind, its speed, the degree of the rolling of the boat, the frequency of the oscillations, the rolling, pitching and yawing angles and the accelerations with respect to a reference system; motorized drive means for hoisting and lowering, or else winding and unwinding at least in part the sail; a control unit (CU) programmed to automatically control the drive means of the sail in feedback based upon the detected quantity, or else following a command imparted by the skipper. The invention concerns, in a second aspect thereof, a method for adjusting the surface of the sails in feedback based upon the detected quantity.

A winch (1) for nautical use comprises a stator body extending along a longitudinal axis (X-X) and adapted to be mounted on a sailing boat; a rotary body (20) rotatably associated with the stator body so as to be free to rotate with respect to the stator body in a first direction of rotation (R) and to be locked with respect to the stator body in an opposite direction of rotation, and a circumferential throat (30) for locking a line (100) for manoeuvring a sail of the sailing boat, the throat (30) being fixedly mounted onto the rotary body (20). The winch also comprises, in a first operative configuration thereof, an element (40) for guiding the line (100) in the throat (30). The element (40) defines, at the throat (30), a maximum radial dimension of the winch. According to the invention, in a second operative configuration of the winch the maximum radial dimension of the winch at the throat (30) is given by the maximum diameter of the throat (30). Such a winch operates, in the first operative configuration thereof, like a conventional self-tailing winch. With respect to these, however, the winch of the invention allows the line (100) to be released and completely freed from the winch by simply pulling the line upwards, and thus in an extremely quicker and easier way. Indeed, in the second operative configuration of the winch the guide element (40) is removed or moved away from the position taken up in the first operative configuration, so as not to hinder the unwinding of the line (100) from the rotary body (20) when the line is pulled upwards.

A fixing group (1) of a watercraft appliance (200) for the attachment thereof to an outer side of a deck wall of a boat comprises a base (201) of the watercraft appliance (200) and at least one seat (3) formed in the base (201) and suitable for receiving a respective threaded fastening element (2), so that said element has a free end (21) projecting from the base (201) for insertion into a respective through hole formed in the deck wall, so as to be accessible from the inner side of such a deck wall for fixing the watercraft appliance (200) to it. The at least one seat (3) comprises an access (31) at a peripheral surface (204) of the base (201) and a retaining portion (32) suitable for cooperating through shape coupling with said threaded fastening element (2) to prevent the rotation and axial sliding thereof with respect to the base (201). The invention also refers to a method for attaching a watercraft appliance (200) comprising said fixing group (1) to a deck wall of a boat by means of threaded fastening elements (2).

A device (1) for actuating sheets of sailing boats comprises a pulling element (2) for a sheet (200) and an actuator (3) connected to the pulling element (2) for causing the motion thereof. The actuator (3) comprises a screw (4) and a nut (7) engaged with each other, wherein one from the screw (4) and the nut (7) is rotated and the other translates linearly. A boom (300) of a sailing boat (100) provided with the device (1) for actuating sheets of the invention is also described.
