  • Patent number: 10442516
    Abstract: A marine propulsion system having a steering axis that allows pivoting of propellers along a first vertical axis directly beneath a gear box located inside the hull of a boat. A lower gear box can be placed within a vented or non-vented tunnel eliminating the need for a rudder and providing directional control of the boat by the orientation of the lower gear box. Surface piercing propellers and/or counter-rotating propellers may be used with the propellers pivoted around the vertical axis of the gear box. The offset steering axis allows pivoting around the first vertical axis wherein a secondary axis is moved with minimal drag providing superior maneuverability at both high and low speeds.

  • Patent number: 10442514
    Abstract: A human powered watercraft or land vehicle is described herein. A watercraft or land vehicle may have two pedals that reciprocated are in a linear or slightly curved trajectory but not a circular motion. As the two pedals are reciprocated, an output shaft is rotated in either a clockwise or counterclockwise direction when the left pedal is pushed forward or when the right pedal is pushed forward. The output shaft may be connected to a propeller of a watercraft or a land vehicle so as to propel the watercraft or land vehicle forward. The output shaft may receive rotational input through two gears mounted to the output shaft with one-way bearings that enable the output shaft to rotate in the same direction regardless of whether the left pedal or the right pedal is being pushed forward.

  • Patent number: 10442508
    Abstract: A two-section kayak is disclosed where a user can create a gap between a kayak front section and a kayak back section, and use this gap to enter and exit the water. Connecting poles are preferably used to create the gap and retain structural integrity of the kayak when the two sections are separated. A variety of foot stirrups and ladders are contemplated to allow a user to more easily reenter the kayak through the gap. One or more gap alcoves are contemplated to store a stirrup or ladder and to allow the user ready access to swimming, snorkeling and scuba diving accessories while in the gap. A viewing portal, and a hanging seat/platform are contemplated for attachment in the gap, to allow users a more varied kayaking experience. An optional third kayak section is contemplated to add storage space or turn a single kayak into a double kayak.
