ABSTRACT:
Apparatus, such as a chute or boom, attached to the stern of a ship permits towed body to be launched and retrieved without damaging the hull of the ship. The chute includes a plurality of telescoping sections coupled to one another through a locking and release mechanism operated by a cable assembly. In a preferred embodiment, launch contemplates extension of the chute and activation of the cable assembly so that the chute telescopes open to a locked full extension. The towed body may then be released through the chute to its towing position. Retrieval involves first recapturing the towed body and drawing it up through the chute into the ship and then activating the cable assembly and retracting the chute so that the chute is telescopically folded back to its initial position with the towed body stowed in the chute ready for its next launch.
