摘要： A subwoofer that is enclosed in a housing adapted for tool-less installation and removal on a watercraft using cam-latch mounts on existing vendor mounting locations or on included custom mounting plates. The watercraft subwoofer system includes a waterproof signal and power connector with no tools necessary to connect or disconnect. The down-firing subwoofer acoustically couples the subwoofer to the hollow vehicle hull and increases bass. The enclosure has a passive acoustic radiator to provide increased bass response and pressure equalization when hitting the water or momentarily submerged. The enclosure has marine lights on the rear-facing side. The enclosure also has a one-way pressure valve to release pressure if hitting water at high speeds and becoming submerged. An anti-slip mat is provided on the top of the enclosure to reduce the likelihood of a rider slipping off the rear of the watercraft. Various enclosure shapes may be used.

摘要： There is described a watercraft comprising a housing having a hull and a deck, the hull shaped to cause the watercraft to operate in a displacement state and a planing state, a powerplant in the housing, and a propulsion device drivingly engaged to the powerplant to generate a propulsive force to propel the watercraft. A controller is configured for monitoring an operational parameter of the watercraft, the watercraft having a range-efficient operating regime following a transition of the watercraft from the displacement state to the planing state, the operational parameter having an optimal state for the range-efficient operating regime. A user interface is coupled to the controller and configured for providing a visual indication of a status of the watercraft in relation to the range-efficient operating regime.

摘要： Methods and systems for operating powersport vehicles during an operator-vehicle separation condition are provided. One method includes detecting the operator-vehicle separation condition using a first tetherless criterion and a second tetherless criterion. In response to detecting the operator-vehicle separation condition using both the first tetherless criterion and the second tetherless criterion, the method includes preventing propulsion of the powersport vehicle.

摘要： A jet propulsion watercraft includes a vessel body, a jet pump that is disposed at the vessel body and that includes a water jet opening, and a first guide that is attached to the vessel body. The jet pump generates a thrust by sucking in water existing around the vessel body and jetting the water from the water jet opening. The first guide receives water flowing on a lateral side of the vessel body and generates a downforce that generates a wake behind the vessel body.
