PURPOSE:To prevent a cavitation on the top of a submerged body from occur ring, by installing a turbulent flow acceleration pin upright in the torpedo-type submerged body fitted in the lower part of a bow part. CONSTITUTION:A torpedo-type submerged body 1 is attached to the lower side of a bow part via a slat 3, and at a buttock part, there are provided with each symmetrical pair of propellers 4 and rudders 5. A lot of turbulent flow accelerating pins 2 are installed upright along an upper circumferential surface at a front end of the torpedo-type submerged body 1 whereby a flow of water running along the top of the submerged body 1 prevents a cavitation from occurring.
