The patent relates to a surface tracker for an underwater vehicle which includes a float and a reel mounted to the float. The reel is loaded with a line, the free end of which can be attached to the underwater vehicle. A spring is connected to the reel for biasing the reel in a direction to wind the line on the reel. With such an arrangement, the free end of the line can be attached to the underwater vehicle and the float will trail the vehicle even though the vehicle ascends or descends in the water.
