Hull Pivots About A Vertical Axis Patents (Class 114/61.19)
  • Patent number: 8640640
    Abstract: Inflatable hull configuration and connection for a multihull vessel. The inflatable hulls have a longitudinal structural member fastened to the top of the inflatable hulls, with a central body of the multihull vessel supported on the longitudinal structural members by forward and stern legs. The forward legs support the forward part of the central body through a ball joint that allows the forward legs to rotate as a unit relative to the central body, and have their lower ends attached to the forward part of the longitudinal members, each through a spring supported ball joint. The stern legs are each rigidly coupled to the central body, with their lower ends connected to the aft part of the longitudinal members to allow rotation about a vertical axis and a transverse axis, but not the longitudinal axis. A detailed embodiment is disclosed.

  • Patent number: 8641465
    Abstract: A water walking apparatus having a pair of inflatable pontoons with footwells at their center, allowing user to step into. The pontoons are connected together by stretch cords and a platform that allows the user to sit and rest after walking on the water. The platform has a ladder inside the cavity of the platform assisting the user to get on the apparatus from water. Pontoons have pockets at bottom for scoops, the scoops pass over water freely when pontoons are going forward, and drop down into water when opposite pontoon is going forward. When scoops are down into water they reduce the backward movement of pontoon. The front ends of pontoons are up and out of water like the bow on a boat. The apparatus can come apart for easy storing and transporting.
