Accordingly, the overall frame structure of the hull forms a king.

Such a king-shaped frame structure has a slight deviation between the bending angles of the buoyancy bodies 11 and 11a around the center tube 92 or the torsion angles of the transverse tubes with respect to the centerline in the longitudinal direction of the hull. By allowing it to have, it responds flexibly to the ripples of the water surface, providing the effect of preventing the frame from breaking in rough waves.

The propulsion device 21 is installed in the vertical tube 22 so that the user stepped on the vertical tube 22 and the user to step in the longitudinal direction of the hull and the front tube 91 and the central tube 92. A housing 25 provided vertically downward at a position of the crank 24 and the crank 24 of the vertical tube 22 which share the rotational axis with the pedals 23 and 23a and the pedals 23 and 23a.
