Abstract : Results are presented from an investigation of the hydrodynamic forces and moments acting on modified rectangular flat plates with aspect ratios of 1.00, 0.25, and 0.125 mounted on a single strut and operating near the free water surface. A simplified method of obtaining the lift characteristics in unseparated flow at large depths is presented. The experimental effects of changing the angle of attack, depth of submersion, and aspect ratio are presented. The effects of cavitation and two types of high-angle leading-edge separation are also presented
