Boat Blade
The blade in a boat engine is sharp enough to hurt sea creatures and humans, alike. Weeds and plants too can wreck it. The Air Booster is a redesign that removes the propeller blades and uses air pressure to move the boat. A safer out look no doubt, but will it work? That is the question!
