In the craft, a front arc-shaped tube (1) and a rear tube (2) are separately formed on an upper outer edge of a hull (4). The front arc-shaped tube (1) is fixed to both sides of the hull (4), and a sliding rail (6) is installed on both sides or one side behind the front arc-shaped tube (1) backwardly in the longitudinal direction of the hull (4). The rear tube (2) can slide on the sliding rail (6). First coupling means to be attachably/detachably coupled with each other are equipped on a rear end of the front arc-shaped tube (1) and a fore end of the rear tube (2).
