Abstract : The hydrodynamic design approach and basin evaluation of a cable-towed vehicle are presented. The resulting body form reflects several features which were included to reduce cost of fabrication. The results of the basin evaluation indicate that the simplifying features did not significantly compromise the towing characteristics of the vehicle. The vehicle will perform satisfactorily at speeds substantially above the nominal design speed of eight knots. Furthermore, cable predictions, also presented herein, indicate that at eight knots the design operating depth of 250 feet will be achieved with slightly less than 500 feet of wetted cable length.
