Tests on model of single screw tug; resistance experiments were conducted at speed-length ratios of 0.40 to 1.30; propulsion experiments both free running and with various towing pulls, were made over same speed range and in bollard condition, with 3 different propeller designs; results for 100-ft ship are shown in tables and curves.
