Summary:

A 1/7.06 full-size model of the NC-type hull was tested in the N.A.C.A. tank by both the general method and the specific or free-to-trim method. The results of the tests were given in curves plotted as nondimensional coefficients and are compared with the test results of N.A.C.A. model 11-A.

The NC model (N.A.C.A. model 44) shows higher resistance than model 11-A at hump speed but lower resistance at high speeds. Model 44 has a higher best trim angle at the hump and a lower maximum positive trimming moment than model 11-A. At high speeds the speeds the best trim angle and the trimming moments of the two models are approximately the same.
