Abstract: In one embodiment, a control device for a trim tab of a boat includes a plurality of stabilizers, one of each provided on each side of the boat, and a joystick. The stabilizers include blades and a control actuator for each blade, which determines the regulation of the angle of each blade in respect of a plane identifying the transom of the boat. The joystick is connected to a control circuit, which generates a command signal based on a movement of the joystick and coordinates the position of each of the stabilizers, thereby causing the bow of the boat to move in the same direction as the joystick.

Abstract: A steering system for boats includes a control member of the steering wheel type, lever type or the like connected to a driving shaft of a transmission composed of at least two transmission elements dynamically engaged one with the other, of which one is an input and the other one an output elements. The output element drives a member transferring the motion of the control member to an operating unit, such that a movement/rotation of the control member is transmitted to the transfer member through such transmission. Moreover, at least the input element is produced from a material obtained by a sintering process.

Abstract: A single lever control for combined control of the throttle in a marine engine and of a reversing gear includes a rocking lever mounted onto a supporting arm, which is connected to an actuator causing a reversing gear to transmit engine motion to a shaft driving a propeller or the like either in the same direction of rotation as the drive shaft or opposite thereto.

The signal is transmitted to a controller of a motorized actuator of the engine throttle. The angular displacement of the lever is transmitted to a transducer converting rotary motion into an electric signal uniquely related thereto via a gear drive having an input gear controlled by the supporting arm and an output gear connected to a transducer control shaft.

Abstract: A joint connecting a cylinder actuator of a trim tab to a watercraft includes a first part couplable to a wall of the watercraft, a second part couplable to the cylinder actuator, a pin coupled to one part and a pin seat formed in the other part. In one embodiment, the seat is defined by a portion of a circular cylindrical surface having an opening on one side. The surface portion has an angular extension larger than 180°, and the pin has a correspondingly cylindrical portion with a laterally flattened surface for introduction into the opening of the pin seat. The opening of the cylindrical pin seat and the flattened portion/s of the pin are in such reciprocal angular positions that the two joint parts are operably connectable and disconnectable by disposing them in a relative angular position, which cannot be attained in the mounted operating condition.

Abstract: A directional control system for a marine vessel comprising a steering mechanism movable between two extreme opposite positions and capable of altering the direction of the marine vessel; an actuator for moving the steering mechanism between the two extreme opposite stop positions; a directional control station comprising a control element movable between two opposite positions to set a directional steering; and an electrical transmission system transmitting to the actuator the movement stroke of the control element or the position of the control element in the total stroke between the two opposite stop positions. The electrical transmission system transforms the movement stroke of the control element, or the position of the control element, into an actuation signal for the actuator according to a function univocally correlated with the position of the steering mechanism, thereby causing the steering mechanism to assume a steering position that directly corresponds to the actuation signal.
