一つであるが、造波抵抗を小さくできる加盟という段階
であり、粘性抵抗低減の具体的方法は未だ出されていな
い。(Prior Art) Various types of high-speed ships have been devised, and 5VASH is one of them, but it is still at the stage of joining the system to reduce wave-making resistance, and a concrete method for reducing viscous resistance has not yet been proposed.

When considering the underwater hull of the SH as being divided into two parts, an upper hull H□ and a lower hull H2, the upper hull H1 is curved from bottom to top and opens in an inverted eight shape. This structure provides an optimal cross-sectional shape for minimizing wave-making resistance due to interference between the upper hull H1 and lower hull H2 during high-speed navigation.

ることができる。(Function) The viscous resistance of the hull is considered to be proportional to the size of the flooded surface area. Therefore, as in the present invention, the frame line 1 of the upper hull is made straight, so that the flooded surface area can be made smaller than that of the frame line of the known 5WASH as shown in FIG.

抵抗のうちの粘性抵抗を小さくすることが可能となった
。(Effects) Since the frame line of the upper hull of the hull below the ice surface was configured as a straight line, it was possible to reduce the flooded surface area and to reduce the viscous resistance of the resistance that the hull is subjected to.
