Since not too much information is available for cargo vessels designed to operate in the Frou de Number speed range of F equal 1.10 and above, a series of tests was made on the models designed to operate in this range in order to determine the expected resistance the ship should encounter and to determine the propulsion power which will be necessary in order to operate in this range. The article describes the considerations of the hull parameters in order to restrict the test program yet gather the necessary information. It was decided to restrict the type of ship to one of 20,000 cu. m. displacement volume with LBP of 160 meters and draft of 9.15 meters operating at speeds below F equal 1.3. The three models were tested to determine the influence the largest-section-coefficient has on the power requirements. In order to restrict the propulsion tests the speed range, with propulsion of 40,000 SHP at 26 knots, went up to 27 knots. The article then describes the design of the hull, propeller, and stern arrangement to suit the testing requirements. The results of the tests are compared with a Taylor form block coefficient to determine resistance at a given largest-section-coefficient, and it is found that the smallest largest-section-coefficient has the least resistance, and generally it also has the minimum power requirement.
