Straight wall slideway type round bilge speed boat shape

The invention discloses a straight wall slideway type round bilge speed boat shape which is characterized in that a boat body comprises two straight wall round bilge lateral bodies in left-right symmetry, slideway tops and slideways, the straight wall round bilge lateral bodies are formed by straight wall contour lines, slideway contour lines, stern cross section lines, stern bottom oblique ascensions, midship cross section lines and midship bottom oblique ascensions. The straight wall slideway type round bilge speed boat shape has the advantages that during sailing in the transition state and the sliding state, waves and flying foams on the outer side of the boat body are reduced greatly, the waves, flying foams and air flows on the inner side of the boat body flow through the slideways and flow out towards the rear of the boat at high speed, parts of the energy of the waves and flying foams on the inner side of the boat body are recycled by the slideways (equals to wave and foam elimination) and converted i
