Number of hydro dynamic designs have been evolved to reduce the high hydrodynamic drag and high water resistance at high speeds, still there is a need to reduce hydrodynamic drag further. For floating vehicles there is no need of energy to float against gravity because vehicle is already on float in water, but energy is required to move marine craft ahead. Most of the thrust energy is consumed to replace the water at fore of the hull. Thrust energy requirement is reduced in this invention compared to any existing marine-vehicles.

at least one power source means configured to supply power to generate torque energy to rotate said water impeller and/or water compressor;
at least one water-jet nozzle to release fast moving water to generate thrust;
a control mechanism;
comprising steps of:
a. creation of low pressure at fore of said hull by means of operating said water-impeller and/or said water-compressor thereby the said low pressure minimises the drag caused due to water attack on said hull during cruise of marine-vessel and generates pulling force.
b. energising said sucked water by kinetic and potential energy by means of operating said water-impeller and/or said water-compressor thereby filling and delivering continuously said energised water to said sucking tunnel conduit.
c. diffusing the said energised water through said water-jet outlet resulting generation of thrust.
