  • Patent number: 3941072
    Abstract: A steering system that is easily attached to and removed from a canoe wherein the system includes a first frame section having adjustable brace members and a sling assembly for gripping the end edge of the canoe. A second frame section, pivotally secured to the first frame section, includes a pair of rudders and associated steering mechanism. A motor mount may also be provided on the second frame section for supporting an outboard motor such that when an obstacle is encountered beneath the surface of the water, the entire second frame section, including rudders, steering mechanism and motor, pivots from a downward operative position to an upward inoperative position, thereby bypassing the obstacle and preventing damage to the system.
