Abstract: The present invention relates to an arrangement (100) for a sailing boat furling system, and for reception of or comprising an outgoing shaft (11) exposed to external torque loads. It comprises a furling drive unit (20) with a gear mechanism (22) and a motor unit (23) connected to an ingoing, motor, shaft (21) and a ratchet mechanism (10) comprising a locking functionality. The ratchet mechanism comprises a housing (17A,17B) and takes up the outgoing shaft (11). The furling drive unit (20) is connectable to ratchet mechanism (10) and is so arranged that the motor unit (23) will be located distant from the outgoing shaft (11), and it further comprises a control unit (30) arranged to control the motor unit (23) driving the ingoing shaft (21).

Abstract: An arrangement for voltage conversion for a boat, for example a leisure boat, includes a DC voltage converter that converts a first DC voltage provided by a low voltage source, for example a battery, to a second DC voltage of at least 24 V for supplying at least one consumer with power. The arrangement also includes an interconnector for interconnecting the voltage converter and the at least one consumer, and a controller that is adapted to transfer the voltage converter between an idle mode, in which substantially no power is supplied to the at least one consumer, and an active mode, in which power is supplied.

Abstract: The invention relates to a device (10) at a cleat (1) for a sailing boat in order to provide detachable locking of the line (3) to a sail, a rig or the like, where the line (3) runs over a sheave (2) on an elevated level and having cleat (1) for locking the line (3) situated at a distance from the deck of the boat. According to the invention, the line (3) is arranged to run over a sheave (2), which is provided with ratchet back stop (5). The line (3) is in that connection arranged to directly co-operate with a movably actuatable mechanism (14), which is arranged to activate the ratchet back stop (5).

Abstract: The instant invention concerns a proceeding and an arrangement in connection with a winch for a sheet or a halyard on a sailing boat. This is, besides for sheeting-in, constructed to also allow veering-out of sheet or halyard rope arranged thereon by means of means that normally otherwise are intended for sheeting-in, more precisely a crank possibly having an appurtenant transmission integrated in the winch or the corresponding motor drive and appurtenant transmission, for driving of a drum belonging to the winch and a self-tailing unit arranged at the upper end of the same. The last-mentioned one has upper and lower rope guide rings as well as means in the form of an expedient arm for directing the rope into and out of the self-tailing unit in a controlled way. The invention embraces suspension and spring-mounting means for at least one of the rope guide rings that are arranged in such a way that this/these obtain(s) a mutually static and dynamic motion pattern.

Abstract: Method and a device (1) at a motor driven line winch (2) for sailing boats comprising a rotatably mounted line drum (3) around which a line (4) for sail and halyard is windable. According to the invention, more than one electrical motor is arranged in order to in different manners in different engagement patterns be possible to be coupled together in order to thereby actuate the winch (2) by different desired power and be able to optimize the total efficiency of the device.

According to the invention, the line (3) is arranged to run over a sheave (2), which is provided with ratchet back stop (5). The line (3) is in that connection arranged to directly co-operate with a movably actuatable mechanism (14), which is arranged to activate the ratchet back stop (5).

Abstract: An arrangement for a sail for sailing boats to connect the sail to a mast (4) on the sailing boat by means of a number of mast track slides (6) distributed along one edge of the sail, which are so arranged as to be connected by means of rolling devices to a track extending along the mast. The rolling devices are accommodated jointly in a channel-shaped track (9) integrated with the mast (4), with the edges (18,19;21,28;22,29) of which the aforementioned rolling devices are so arranged as to interact. A channel-shaped opening (16) extends along the aforementioned track (9) to permit the track slides (6) to extend out from the aforementioned track (9) with a narrower part for attachment to the sail with a broader part.

Abstract: The invention relates to an arrangement for the detachable locking of a line (2) which is led out through an opening in, for example, a mast (55) on a sailing boat (6) in question and for enabling the line (2) to be led further to an existing winch on board. In accordance with the invention, a tension release device (1A) and a ferrule (1B) for the line (2) are formed by a common component. Each part of this common component (1) can be situated to either side (A and B respectively) of the wall (12) in the mast (5) and or a cockpit, through which a lead-in (11) for the line (2) extends.

Abstract: The invention relates to an arrangement for a boom on a sailing boat which carries a sail capable of being wound onto a mast. Actuation of the sail is with a force F from a drive motor. In conjunction with this a rotatably driven screw accommodated within the boom is capable of attachment on one side of the aforementioned drive motor and is connected on the other side to the sail via a movement transmission.

Abstract: The present invention relates to an arrangement for a driving device for sails on a boat and comprises a worm gear acting between the driving device and a sail furling stay and/or sail furling shaft on the mast. In order, amongst other things, to obtain a compact driving unit, and thus to reduce the space requirements on board the boat in question, the driving device is accommodated internally within a space in the worm gear, inside its worm gear screw, with the driving device arranged coaxially with the screw.
