<p>Winches for towing behind a boat a sonar-equipped fish-shaped submerged body. The invention consists in measuring the trim (118) in the region of the submerged body (117) and controlling, based on this measurement, a servo-control cylinder (106) which alters the inclination of the arm in order to maintain a constant trim. The winch diminishes the jerks due to the tractile force on the cable towing the submerged body.</p> |
