[Vessel design for improvement of speed by reduction of hydrodynamic drag] Abstract: A marine vessel designed for improving its vessel speed by the reduction of hydrodynamic drag comprises a substantially hull having a bow and a stem with a defined projected raised position over water level towards the direction of motion in use. At least one substantially linear propulsion channel aligned along the bow-stern elongate axis of the hull with at least one thrust device for forcing water through the channel. Wherein the propulsion channel defines position below water surface in taking water from under the bow and discharging behind the thrust device and then out of channel. Wherein under water at least one aviation driving system is mounted to drive the entire said invention for keeping said hull staying above water so as to substantially reduce bow front pressure and frictional resistance on the hull external of the forward motion so as to reduce its hydrodynamic drag. Said invention comprises several foldable and retractable operations on its aviation system, propulsion system, framework and related structure for obtaining a minimum size and depth on passing through shallow waters or mooring to berth.
