Abstract
A vessel operable by a diver for use in towing himself has an air motor powered by the diver's air tank. All or part of the air used by the diver passes through the motor. Air used by the motor in excess of air needed for breathing is exhausted into the vessel wake to reduce drag. A manifold, connected to the diver's air breathing means and to the tank, provides air connections to the vessel during towing operations and is quickly detachable and provides connection from the tank to the air breathing means when the diver operates away from the vessel.
