Drive and control system for watercraft

InactiveUS20010042498A1High possible performance and overall efficiency and overall utilityLeast possible vehicle emissionWaterborne vesselsWater sport boardsPower stationFlight vehicle
A surfboard-based powered water craft is propelled by gas or electric power plant. A water jet pump supplies water under pressure, which is exhausted through a steering nozzle. A steering shaft, carried by the surfboard-based body, pivots in response to movement of a steering arm. The steering arm pivots about a vertical axis and a horizontal axis. The weight of the power plant is carried forward the center, whereby a rider on top of the surfboard based body tends to balance the weight of the power plant.

Surfboard fin mounting system

Provided is a system including a fin box that allows surboard fins to be installed, removed or adjusted to the front or rear of the board within the box and a means for installing the box on the surfboard. More importantly, the fins can be installed in the fin box, and adjusted or removed from the fin box without the use of tools. By using the fin box installation system, manufacturers can effectively locate, align and install the fin box on the surfboard. More importantly, the manufacturers are able to lean and rotate the fins precisely at any desired angles and achieve precise and critical symmetrical mounting of the fins with relation to the centerline of the surfboard.

Paddle-integrated wireless controller

Wireless transmitters are integrated with manual marine-propulsion implements associated with small watercraft (paddles, oars, poles, and the like). The transmitters are controlled by hand-operated actuators. The actuators are designed to be manipulated without looking and positioned within convenient reach of an operator's normal hand position on the implement. A corresponding wireless receiver on a target device enables the transmitter signal to control the device. Thus, an operator of a small watercraft can control a useful target device without first shipping or otherwise securing the manual implement, and may simultaneously continue to manually propel or steer the watercraft with the implement. Application examples include a propulsion-assist motor on a stand-up paddled (SUP) surfboard.

Clean energy powered surfboards

Clean energy powered surfboard having various advantages that make for easy to learn, easy to use, safer, exciting, high performance, environmentally friendly surfing on any ocean wave in the world. The various embodiments include novel motor, turbine, or electric motor generator surfboards comprising hydrogen or electric-powered motors, which can be switch-activated and which drive jet pumps. Energy can be stored as compressed gas, including air and hydrogen. Energy can be stored in novel capacitors that are incorporated in the body of the surfboard. Energy can be generated by solar or water power while surfing or by passing waves, for example, while waiting for a big wave. An output jet provides thrust to catch a wave, to return to the wave breaks, or to avoid a hazard. A novel fin output jet increases stability and maximizes thrust. Self-contained, self-recharging embodiments are low cost, lightweight, safer, and good for the environment.
