Abstract
A deep water tow system adapted for being towed by a tow cable behind a ship includes a buoyant tow vehicle for housing apparatus to be used underwater, a coupler for connecting the tow vehicle to the tow cable, and a weight in the form of a multi-link chain attached to the tow cable at a location some predetermined distance from the tow vehicle. The chain is of sufficient weight to pull the tow vehicle downwardly in water until the chain contacts the water floor. When pulled by a surface vessel, the chain is pulled over the water floor and the tow vehicle is maintained some fairly constant predetermined distance above the water floor.
