When using power, a rechargeable drill is used, and a drill flexible beat extends in a pipe attached to a key. Moreover, after a drill shaft passes through the pipe, the drill shaft is connected to a propeller to obtain thrust. Without power, an ellipse elastic body made of a component fiberglass leaf spring or a straight muscle training machine is rolled by a foot to obtain thrust in a combined non-powered and powered boat.
