Abstract: In water or on land, an innovative Dual Retractable Handlebar System with adjustable damping, allows the rider of Motorized Surf Boots to transition from a kneeling, to squatting, to standing, or vice versa, in one smooth articulated motion while keeping a continued grip on the handles and throttles. Each handlebar of the pair is firmly connected to each boot (or board) safely behind the rider, with each handlebar extending around the outside of the rider to a comfortable and ergonomic position to grasp with each hand, providing the rider with the ability to impart body English on the left and right sides independently, in order to effectively steer his or her Motorized Surf Boots on water or on land. Additionally, the pair of Handlebars of the present invention can be quickly locked in the retracted (or down) position, or quickly released for deployment in a range of up positions.

Abstract: A marine vessel can be propelled by using wind or solar energy. This propulsion results in the forward movement and six degrees of motion (roll, heave, pitch, yaw, surge, and sway) of the marine vessel. This invention capitalizes on the fact that solar, wind and wave energy are cyclical by nature. The invention enables the vessel to manage stored and harvested energy and use the stored energy during periods when the external natural sources of energy are not available in adequate quantities to maintain a reasonable speed of advance for the vessel. The vessel's natural energy management system (NEMS) manages it in such a way that harvesting of the energy during high energy cycles, storing it and using it when needed during low external energy cycles, allows a marine vessel to maintain faster average speed without reliance on any fossil or chemical fuel and by only using renewable energy sources.
