摘要

The carcass has steps closed by transverse chine band. A balance point of a motor and a gear, and front steps of a carcass base lie more than 40 percentages of a boat length before a rear of the carcass. The steps are arranged in such a manner that a sternmost sliding surface of the base controls a rocking motion of the boat by supporting effect of the boat. The supporting effect is optimized by trimmer clasps. The trimmer clasps are in contact with the water surface, and transfers function of a steering gear.
