This is a model of the Super Hawaii ocean racer. The model is 60" long with twin electric Lehner 2280 motors. The batters are twin 8s lipo. The boat totals out at 28 pounds plus. So far the boat has topped out at more than 45mph with an onboard GPS and we fell it can do much better. This is the revised edition with constructions photos. Built by my brother Bill Proffitt, St Petersburg, FL
