Title (EN) STEERING SYSTEM FOR PLANING WATERCRAFT
(FR) SYSTEME DE PILOTAGE POUR EMBARCATIONS DU TYPE A COQUE PLANANTE
Abstract:
(EN) An arrangement in a steering and propulsion system for a planing type motorboat (10), which boat is provided with means (16, 18, 19) for adjusting the trim position. The steering characteristics of the boat are improved by providing the steering mechanism (15) with a sensor (20) for detecting rudder displacement, which sensor (20) is connected to said trim position adjustment means (16, 18, 19). The sensor is connected to the adjustment means (16, 18, 19) via a microprocessor (21) for recording the degree of steering displacement, which microprocessor is adapted to trim down the bow of the boat in the water when a certain steering displacement is exceeded.
(FR) Agencement d'un système de pilotage et de propulsion pour embarcations à moteur du type à coque planante (10). L'embarcation est munie de dispositifs (16, 18, 19) destinés à régler son assiette. On peut améliorer les caractéristiques de pilotage de ladite embarcation en munissant le mécanisme de pilotage (15) d'un détecteur (20) du pivotement du gouvernail, ledit détecteur (20) étant raccordé auxdits dispositifs de réglage de l'assiette (16, 18, 19) par l'intermédiaire d'un micro-processeur (21) servant à enregistrer le degré de pivotement de gouverne et apte à équilibrer l'embarcation lorsqu'un seuil de pivotement de gouverne est dépassé.
