The present invention relates to an assembly swimming boat for leisure. The present invention uses a freestyle swimming technique that kinetic energy is converted into the kinetic energy again via elastic energy to double the power when the little power is applied to a human leg even if there is no power source. Therefore, a thrust is provided to the boat with the big power. The present invention comprises a handle, enables a spring to be mounted inside a cylinder, and obtains an elastic force using a leaf spring to obtain energy maximally using a point of center of gravity and the weight of a human. Therefore, the present invention can obtain large energy thrust with the little power. |
