Small Homemade Hydrofoil Boat

First trials of a small homemade hydrofoil boat. The engine could not be run at more than 2/3 power because it was mounted too high. One can clearly see propeller spray, indicating the propeller runs too high in the water. Therefore the top speed could not yet be determined, but at around 2/3 power, it reached 21 km/h. More testing to be done after modification of transom.
