Semi-submersible small-waterplane-area remote control sailing boat with surface grooves

The utility model relates to a semi-submersible small water plane remote control sailing boat with a surface groove. The sailing boat comprises a sailing boat main body, a supporting column, the surface groove, a mast, a rudder, a sail and a floating body. The supporting columns are a left supporting column and a right supporting column which are connected through a connecting bridge and symmetrically arranged, and surface grooves are distributed in the supporting columns. The mast is fixed in the middle of the sailing boat body; the two rudders are symmetrically distributed at the tail part of the ship bottom; the sail is installed in the middle of the hull. The optimally designed small water plane structure is applied to the remote control sailing boat, the advancing resistance of the boat body is reduced as much as possible under the condition that the strength, rigidity and stability of the boat body are guaranteed, and the sailing speed of the sailing boat is further increased. 本实用新型涉及一种带有表面沟槽的半潜小水线面遥控帆船
