Publication number: 20200307734Abstract: A sit-astride amphibious vehicle configuration which supports a high performance envelope both on land as well as in water. The vehicle has a planing hull and four retractable wheels. Handlebars provide for directional control in both modes of operation. Each road wheel is retractable by pivoting through at least 45° so as to maximize ground clearance when in the land mode of operation and to minimize drag at substantial lean angles when in the marine mode of operation. While a jet drive may remain directly connected to the engine at all times, the driven wheels are only connected during land mode via a speed-change transmission. The entire power train is supported by a frame that is separable from the hull which in turn has a detachable top deck portion, whereby such configuration simplifies the construction, repair and servicing of the vehicle.Type: ApplicationFiled: January 10, 2020Publication date: October 1, 2020Applicant: Gibbs Technologies Ltd.Inventors: Simon James Longdill, Hans Weekers, Stephen John Briggs, Alan Timothy Gibbs, Neil Graham Jenkins
