Bottom Paint

One of the mysteries of boats is how they float on their bottoms. That's only part of it. They move through the water and get struck by waves and and the occasional rock. It turns out bottoms also attract organisms that grow there, slow the boat, and eat away at the surface. To prevent organisms from growing on boat bottoms, normally economic and ecological sailors resort to painting boat bottoms with expensive copper paint. The paint is at least $100 per gallon and the copper is not good for local harbor organisms. I can't wait for someone to invent a boat bottom that needs no paint, is smooth as silk, and can hits from waves and rocks.
