A wave devouring propulsion system(WDPS)is a thrust generator of a ship and also used as a motion stabilizer, which converts wave energy directly into trust and efficiently reduces the hull motion in the waves. The WDPS concept consists of the hull and hydrofoil system. Generally one solid hydrofoil system is set in front of The ship bow and connected to the hull with pin joints and supported with soft springs to give the restoring force about the foil pitch motion. The experimental results of a newly designed dual fin type WDPS and hydrodynamic wave forces acting on the foils are shown in this paper. In the previous discussion of WDPS, which is related to the mechanism of thrust generation of single hydrofoil located at the incident waves, the heading sea condition is more suitable than any another wave direction. But the newly developed WDPS test shows that the fastest speed is achieved with a beam sea condition.
