Dad Has Another Project

My dad is at it again. At 83 years old he is completely fired up about building my brother a Hydroplane and going after the National Championship. After 20 years out of racing My brother wants to go after it big time. So they called on Brother (me) to supply them with some plans. So I dug into the arkives and wah lah.... A World Champion Hydroplane.
Dad likes helping his boys. The old engineer in him has come out big time. This should be interesting and chalanging.
