The purpose of this research is producing a Human-Powered Hydrofoil, using a chain to be the propel system. Adjust the chain to 90 degrees, and then roll the propeller with the bicycle-like method to produce power to launch. By tightly connecting the chain and the gear wheel, the transmission system can overcome the resistance of water and the chain is not easy to derail. Using inflatable pontoon that holds a larger displacement, it can reduce the resistance of water in order to increase the navigating speed. With two kinds of designs, the wing in the water will generate enough power to rise up, so that the pontoon will raise above the water and fly.
