Meet Hulltimo ($26,620). It's a hull-cleaning robot that helps ensure smooth sailing, or motoring. The unit is controlled via a hand-held video panel, and the robot uses soft spinning bristles (think the ones used at a carwash) and a gentle cleaning solution, removing slime and growth buildup. There's no negative impact on your yacht's bottom paint, and debris from the scrubbing collects in a bag instead of being released into the water.
