The steady potential flow about a TP 620 hydrofoil, flying in air above a dynamic water surface. is calculated by the one dimensional theory as the clearance-to-length ratio tends to very small. The characteristics on water surfare effects of air supported TP 620 hydrofoil over water are compared NACA 4412, NACA 66 and plate. respectively. It is found that using the TP 620 hydrofoil is superior lift coefficients. Moreover for trailing edge shape of the hydrofoil, high lift coefficients at 1 Fmn can be obtained.
