Abstract: The invention refers to a drive system of the servo-pneumatic type for activating/deactivating motion transmissions in sailing boats. The drive system of the invention is adapted to activate/deactivate motion transmission operating configurations, or for shifting from one motion transmission operating configuration to another one, when a drive is given by a crew member, much more rapidly than with the mechanical drive systems known in the art. The drive system of the invention can be used, for example, for activating/deactivating the motion transmission between pedestals and/or between pedestals and winches, or for driving the shift from one winch speed to another one, or to prevent the deactivation of a first winch speed when shifting from a first speed to a second speed, or also for driving any speed multiplier connected to the winches.

Abstract: An actuator (100) for actuating an onboard device (200) on a sailboat (300), comprises: a piston (2) slidably mounted within a cylinder (1) and movable between a first operating position, in which the piston is at a first end portion (3a) of the cylinder (1), and a second operating position, in which the piston is at a second end portion (3b) of the cylinder (1); hydraulic means (101, 15) for supplying a pressurised working fluid at the first end portion (3a) of the cylinder (1), this fluid being adapted to cause the piston (2) to move from the first operating position to the second operating position; pneumatic means for supplying (102, 11) a pressurised gas at the second end portion (3b) of the cylinder, this gas being adapted to cause the piston (2) to move from the second operating position to the first operating position.
