ABSTRACT:
The speed of a high-speed powered boat such as high-speed fisherboats can be increased even at the same power output of the engine irrespective of the speed by providing on each side symmetrically with a plural number of fins each opening outwardly toward the rear end making an angle with the boat hull in at least two high and low rows along the waterline which varies depending on the speed of the boat, whereby the wave-making resistance against the boat is greatly reduced at varied speed of the boat along with a stabilizing effect to decrease rolling. The effect of wave-making resistance suppression can be further enhanced by providing the bow of the boat with a stem-edge guard with right and left wings opening outwardly toward the side lines.
