US 12,617,500 B2 · Rolling reduction boat

Abstract

The present disclosure relates to a rolling reduction boat, and more particularly, to a rolling reduction boat having a structure that allows a rolling reduction tube, which is formed to surround a boat main body, to be filled with water. The present disclosure has the following advantageous effects. That is, according to the present disclosure, by filling a rolling reduction tube, which surrounds a boat main body, with water, there are advantages that the overall weight of the boat is increased, and the center of mass is moved downward and distributed, thus making it easy to get on the boat even in water, and the degree to which the boat tilts or rolls due to external factors such as a strong wind, a wave, and a change in the position of a passenger is reduced and a restoring force of the boat is increased, thus making it possible to more safely sail the boat.
