Now you can give your boat a shine without overworking your arm muscles. The new Ryobi Orbital Buffer can buff away the dullness on your hull without damaging the finish in a fraction of the time it would take to do it by hand. This 10-inch machine has a high-torque, fan-cooled motor and features a random orbit action that closely imitates hand buffing. For around $30, you could own the shiniest boat in the marina.
