They happen to make a warrior controller specifically for boats as well (and I happen to have one in stock). The boat and car software are different, so you would be best served getting the controller specific to your needs. If anything, a car controller would probably work better in a boat than a boat controller would work in a car. Boats don't need/have strong brakes, which is a primary software difference. Physically, the boat controller is much bigger as well (has water cooling).
