Abstract Disclosed is a small power-driven water craft of the type whose body is composed in the main of longitudinal two parts, the deck and the hull, with a standing platform in the deck at its rear portion and a stearing handle in front of the platform. In the deck at its stern side end is provided a mounting board that extends far below the bottom of the hull, adapted to permit a displaced rider to climb on board from the stern, without suffering the usual difficulty in doing so because of the imbalanced state of a craft when it is just floating in the water. In a preferred embodiment, the mounting board is slidably disposed on a sloped surface formed at the stern for movement between a raised position where the board is pulled clear out of the water and a lowered position where it stands extending at an angle into the water, conveniently for a displaced rider to grip on to its surface with his toe or knee in getting on board. Further, the mounting board is moved between the foregoing positions through a wire rope connected to a hand winch whose handle is mounted at a forward portion of the deck, situated low enough to be within the arm's reach of a person near the craft's side in the water so that he, displaced from the craft, can operate the handle to lower the mounting board.
