Three models representing two Bureau of Ships designs and a David Taylor Model Basin design for a proposed 154-ft P04 were tested for resistance and propulsion characteristics. One of the BuShips designs was canceled from the test program after initial bare hull effective horsepower tests. Of the remaining two, the TMB design proved the better in both still water and waves. Significant improvements were made in the performance of the TMB design by the addition of transom wedges. Also of considerable value was the installation of TMB-designed appendages incorporating a single contraflow strut behind the propeller supporting both the propeller shaft and the rudder.
