I saw this and that it was one of the coolest Remote Control boats I have seen in a while! A remote controlled Pirate Ship, I dont know why nobody thought about it before, its genius! It is about 18 inches (45cm) in length which is pretty big and the I think the cannons shoot too, but who cares its like taking a tank through the water, I bet it would be loads of fun.
