Tests were conducted on Model 4914, representing the Surveying Ship AGS, to predict bare-hull resistance and to establish optimum bilge-keel location. Comparison with the corresponding Taylor Standard Series form indicates that at 15 knots the ehp for the bare-hull form is approximately 10 percent higher than the predicted Taylor ehp. Resistance and propulsion tests were also conducted with the model fully appendaged. Test data show that the appendage resistance increased the ehp about 4 12 percent at design speed of 15 knots. A speed of approximately 16 knots should be attained at design power of 3000 shp at 200 rpm. Author
