Abstract : An experimental evaluation was conducted of the towing characteristics of the EMPRESS II antenna barge. A 1/28 scale model of the EMPRESS II was towed in the DTNSRDC deep-water towing basin with measurements taken of tow- line tension and horizontal towline angle. The results indicate that the EMPRESS II can be satisfactorily towed from the bow with a bridle for either of two pulser configurations and for displacements corresponding to the 3- and 7-foot waterlines.
