  • Patent number: 10053197
    Abstract: A pair of rowing devices is installed on respective port (left) and starboard (right) sides of a watercraft such as a rowboat, kayak or canoe. Unlike in conventional rowing the operator sits forward facing the bow (front). By pulling the inboard portion of the oars towards the stern (back) while the blade is in the water, the watercraft is propelled forward. The system described herein reverses the direction of the blades motion through the water using a gearbox. The gearbox also allows for feathering of the paddles, that is, changing the angle of the paddle in relation to the water. This is done by turning the handle throughout the movement of the oars as done with traditional oars.

  • Patent number: 9873497
    Abstract: A marine muffler capable of handling both marine engine exhaust gas and marine engine cooling water includes a double wall baffle partitioning the muffler interior so as to function as a cooling water conduit. The cooling water conduit includes an inlet disposed external to the main muffler housing and an outlet configured and disposed so as to discharge the engine cooling water into the exhaust duct connected to the muffler outlet. The muffler is thus able to convey the engine cooling water through the muffler housing within a dedicated conduit while maintaining the cooling water separate from the exhaust gas. A muffler that is adapted to handle both the exhaust and cooling water flowing from a marine engine allows for the elimination of engine cooling water piping.
