PROBLEM TO BE SOLVED: To provide a shape reducing wave resistance for a high speed vessel having sea speed of Froude number is 0.30 or more.SOLUTION: A vessel shape of the high speed vessel is a vessel bottom shape which: is imparted with an indention 7 on a vessel bottom on a vessel center line in a central area of a vessel extending between 30 percent in the front position and 60 percent in the front position in a vertical length from a stern perpendicular AP in a side shape; having maximum depth of the indention 7 composed varied in a curve state in the longitudinal direction equal to or below 25% of full draft d; and at the same time having the vessel bottom which is linear inclined along approximately rise of floor from the indention position toward outside in the vessel side direction; is a curvature E in a curve shape outside the vessel bottom; and is composed in a cross sectional shape connected to the vessel side in a vertical straight line on a top side of the curvature.SELECTED DRAWING: Figure 1
【課題】フルード数が0.30以上の航海速力を有する高速船において、造波抵抗を低減する船型を提供する。【解決手段】側面形状で船尾垂線APから垂線間長さの3割前方位置と6割前方位置間に亘る船体中央域の船体中心線上の船底に凹み7を施し、該凹み7の深さを最大で満載喫水dの25%以下として長手方向に曲線状で変化して構成され、且つ上記凹み位置から船側方向の外側に向け略ライズオブフロアーに沿って傾斜する直線状の船底とし、該船底の外側で曲線状の湾曲Eとし、該湾曲の上側で垂直直線状の船側に連結された横断面形状に構成される船底形状を有する高速船の船型とした。【選択図】図1
