PROBLEM TO BE SOLVED: To provide a board capable of sailing and being rowed.SOLUTION: A wind surfing extension pipe is divided into two pieces vertically, a seat is attached to a divided lower part for forming a seat having one leg, then the divided lower part is attached to a mast track via a universal joint 8. Then a pair of foot straps 13 is attached to a board on a front part of the attachment point, then a neighbor point of the foot straps and an upper end of one leg of the seat are connected with a reversed-V-shape rope 12 for forming a swing seat 1. In addition, a grip part upper end 16 of a long paddle 14 and a tip end of a board are connected with a constant length rope 15, and the knot of the rope serves as a fulcrum of swing, when a user pulls the long paddle, therefore forward whole body rowing can be performed. On the other hand, when the seat is removed from the board, both parts of the divided extension pipe are connected with a core rod, then the extension pipe is assembled with a mast and sail, and attached to the mast track via the universal joint, thereby the board can be used for sailing.SELECTED DRAWING: Figure 1 |
