Hydrofoilboat homemade

Our first test runs. This is our summer 2012 experiment with home build hydrofoils, using a 5hp outboard shorttail. We made a simple boat from plywood and engineerd the foils (wings) from 3 layers of 18mm plywood. The whole thing with engine weighs about 300 kg and will lift about 100 kg, so a total of 400kg will be lifted out of the water with only 5 hp! At about 10km/h it will start climbing on its foils and will reach a top speed, on foils, of 20 km/h. God created man, man can only engineer and work with
