Robotic vacuum cleaners have been around for quite some time. There are ones for the house and pool, and now… one for your large boat or yacht. The KeelCrab is the first R.O.V for the autonomous cleaning of your boats hull and keel.
A clean hull is a big deal. It can reduce drag and therefore fuel consumption by up to 20%. Less fuel usage equals less pollution and better performance. Not to mention if you keep your hull clean you should have to less haul-outs and use less of the nasty paints. Video of the KeelCrab in action after the break.
