  • Patent number: 5203580
    Abstract: A canoe toting apparatus which enables an individual to manually mount and transport a canoe or similar marine craft over reasonable distances includes a pair of large diameter wheels rotatably mounted on opposite ends of an adjustable length axle. Wheel stabilizers, coupled to the axle, may be pivoted into interfering engagement with the wheels to prevent the wheels from rotating while the marine craft is positioned on the toting apparatus. A pair of resilient guide members are slidably mounted over the axle and adapted to receive the underside of the marine craft. An adjustable length strap, coupled to the axle, is securable about the gunwales of the craft to secure the craft against the toting apparatus.
