An investigation was made to determine the aerodynamic characteristics in the presence of a wing of three deep-step planing-tail flying-boat hulls which differed only in the amount of step fairing.. The hulls were derived by increasing the unfaired-step depth of a planing-tail hull of a previous aerodynamic investigation to a depth of about 92 percent of the hull beam. For the purpose of comparison, tests were also made of a transverse-step hull with an extended afterbody.
