Summary:

The results of towing tests are presented. The first model represents the hull of the U.S. Navy PN-8 flying boat. The second represents a proposed alteration of the PN-8, in which the sponsors of the original hull are removed and auxiliary lifting vanes are fitted at the chines immediately forward of the main step. The tests showed that the altered form gave a large increase in hum resistance and a very undesirable spray formation through a large part of the speed range.
