ABSTRACT:
A deployment/retrieval system for a towed body which includes first and second arms, one of which is rotatable relative to the other about an axle disposed beneath the longitudinal axes of the arms. A winch-wound cable passes through both of the arms as well as around a sheave which also rotates about the axle. Prior to deployment or after retrieval of the towed body the arms are in a horizontal position while during deployment or a retrieval one arm is in a vertical position. When in the vertical position, a complementary mating arrangement on the towed body ensures for a positive engagement with the arm so as to prevent excessive movement of the towed body when captured. In order to reduce tension on the cable for irregular movements of the towing body, one arm assembly is affixed in a bearing arrangement so as to allow rotation about its longitudinal axes.
