A system for towing a marine geophysical sensor streamer includes a lead in line extending from a tow vessel. A streamer front end termination is coupled to an end of the lead in line and to a forward end of the sensor streamer. A floatation device is coupled by a line proximate to the front end termination. A winch is disposed on the floatation device to extend and retract the line. A depth sensor is disposed proximate the front end termination. A controller is in signal communication with the winch and the depth sensor so that the forward end of the streamer is maintained at a selected depth in the body of water.
