Welcome to Team-21

Class of Boat

The boat that I compete in is known as an OSY (Outboard Stock Yamato) 400, this class is a hydroplane class; the boat has a flat Bottom and is about thirteen feet long. It rides just on the surface of the water with only its propeller in the water, The engine is a 400cc Yamato, Japanese made with 33hp, the top speed is just over 70mph. The engine is low compression that enhances reliability. This means it is a stock engine, which has to be kept standard to make competition closer and results more down to driver ability and skill.
