Claim:
1. A water surface transport means, being a mono-hull, comprising a bottom ( 1 ), boards ( 2 ), a deck ( 3 ), surge diversion grooves ( 4 ) and wave suppression diversion baffles ( 5 ), characterized in that, the surge diversion groove ( 4 ) being provided in a space between a bottom surface vertically recessed into the bottom ( 1 ) and the deck ( 3 ), the surge diversion grooves ( 4 ) extending from a bow to a stern, and having an arc-shaped transverse section and a top line of a longitudinal section being lower in the front and higher in the rear; a top transverse section of the wave suppression diversion baffles ( 5 ) being arc-shaped and a top line of a longitudinal section being lower in the front and higher in the rear, top lines of the wave suppression diversion baffles ( 5 ) and the surge diversion grooves ( 4 ) extend backward from a starting point (α 0 ) of a waterline to a first point (α 1 ) by 0°, extend from the first point (α 1 ) to a second point (α 2 ) by a first tilt angle (α 1 ), extend from the second point (α 2 ) to a third point (α 3 ) by a second tilt angle (α 2 ), extend from the third point (α 3 ) to a fourth point (α 4 ) by a third tilt angle (α 3 ), and extend upward and backward from the fourth point (α 4 ) to a fifth point (α 5 ) by a fourth tilt angle (α 4 ), wherein the first tilt angle, the second tilt angle, the third tilt angle and the fourth tilt angle progressively increase by an angle of larger than 0° and less than 5°; a fifth tilt angle (α 5 ) sharply increases by 8°-13° from the fifth point (α 5 ), a sixth tilt angle (α 6 ) progressively decreases from 5° from the sixth point (α 6 ) and to 1°-0° at a seventh tilt angle (α 7 ), and an eighth point (α 8 ) intersects the stern, thus the structures of the surge diversion grooves and the wave suppression diversion baffles evoke hydrodynamic lift L and corresponding hydrodynamic propulsive force P when the mono-hull travels.
