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.
