Abstract: A remote control system for a marine vessel includes a helm transceiver positioned on the marine vessel and configured to communicate with one or more fobs, and at least one operator fob configured to wirelessly transmit a fob signal to the helm transceiver on the marine vessel. A controller is configured to receive the fob signal transmitted by the operator fob and to determine an operator distance based on the fob signal. The operator distance is compared with one or more threshold distances, and then a system command is generated based on the comparison of the operator distance to the one or more threshold distances so as to control operation of one or more devices on the marine vessel.

Abstract: A self-propelled personal watercraft. The watercraft includes a hull with a middle narrower than a bow and a stern of the watercraft and with a bottom of the bow being raised with respect to the middle and the stern, and a propulsion device within the hull. While the watercraft is propelled through water by the propulsion device with a rider on board, shifting of the rider's weight to either side of the watercraft increases contact of the bow with the water on that side, the increased contact resulting in increased drag and turning the watercraft to that side. While the watercraft is propelled through water by the propulsion device with the rider on board and the watercraft is not turning, the bottom of the bow makes contact with the water across a narrower distance than the bottom of the middle.
