A study was conducted on a human-powered hydrofoil that could move on the free water surface. This movement can be achieved when the hydrofoil is operated with pitching and plunging motion simultaneously. Hence, an investigation was conducted to find an appropriate thrust force and operation frequency for various operating conditions. The SD7003 airfoil was adopted for the hydrofoil, and the force on the hydrofoil was predicted using a computational analysis. The numerical algorithm was validated using an experimental result in literature. The thrust force and buoyancy force were obtained by the transient analysis. These forces were calculated to the periodic-averaged forces according to the different operation frequency. In an operation condition of 190,000 Reynolds number, the fast movement was obtained when the amplitude of angle of attack and Strouhal number were 5 degree and 0.6, respectively. For reducing movement speed, the amplitude of angle of attack should be increased.
