Abstract:
Systems and method are provided to protect devices from damage due to floodwaters. For example, a system includes a floating platform assembly, an apparatus securely disposed on the floating platform assembly, first and second platform retaining members connected to the floating platform assembly, and first and second vertical support members disposed on opposite sides of the floating platform assembly. Upper ends of the first and second vertical support members are connected to an outer sidewall of a dwelling, and bottom ends of the first and second vertical support members are fixedly secured at ground level. The first and second platform retaining members insertably receive the first and second vertical support members, respectively. The first and second platform retaining members are configured to slide along the respective first and second vertical support members when the floating platform assembly vertically rises and lowers in response to a changing level of floodwater.
Abstract:
A method and apparatus using a camera and image display for improving navigation of watercraft is presented. The system may be used by a helmsman to view regions outside his unaided sight range. Objects ahead of and behind the watercraft, both above and beneath the surface, may be detected and navigation decisions are made thereby. The same method and apparatus may be used to improve the view in backing a trailer. In any case, the images may be recorded for later viewing.
Abstract:
A boat launch for the pillars of offshore installations includes fender pipes extending substantially perpendicularly to sea level and a ladder being positioned closer to the pillars than the fender pipes. The fender pipes have an inner pipe consisting of steel that is not resistant to seawater and an outer pipe consisting of a seawater resistant metal alloy.
Abstract:
A device mounted on a boat to launch and retrieve the boat from and into water and to drive it on solid ground, comprising a first set including at least one wheel that pivots freely and mounted on a holder in the stem area of the boat, and two second sets each including at least one drive wheel mounted on a holder in the rear area of the boat, with one of the second sets on the port side and the other on the starboard side, said sets being arranged to place the at least one free wheel in the front and the drive wheels in the back on the ground to roll on solid ground and to launch and retrieve the boat from and into water, said sets being adjustable so that the drive wheels come into contact with a slip before the at least one free wheel.
Abstract:
This is directed to systems, processes, machines, and other means that enable a user to launch a kayak from a dock. The invention can easily be cranked into a portable or usable position depending on user preference and enable a user to easily launch a kayak.
Abstract:
An apparatus and method for centering a boat in a boat docking device, such as a boat lift, having a chute into which the boat is directed. The chute being attached to the docking device using lever and fulcrum assemblies that allow the chute to be tailored to the specific application.
Abstract:
The pontoon boat lift system comprises a plurality of lifts. Each lift is comprised of a channel that mounts to deck support members of the boat. A leg is pivotally mounted to one end of the channel. A screw supported in the channel is turned by a connection to an electric motor. A threaded follower on the screw travels along the screw when it is rotated by the motor. A fulcrum arm connects between the threaded follower and the leg to transmit a longitudinal movement of the follower into a pivotal movement of the leg. The leg is thus moveable between a raised and a lowered position. The operation of the lifts is coordinated to raise the pontoon boat above the surface of the water at desired shoreline locations.
Abstract:
The watercraft ramp comprises a frame and a plurality of hull-support assemblies mounted thereon. The frame has a pair of elongated channel rails held in laterally spaced condition. Each rail has a longitudinally aligned internal recess and a longitudinally aligned elongated slot for access into the internal recess. The slot is narrower than the transverse width of the recess. Each hull-support assembly has a mounting bracket, a fastener for fixing the bracket on a rail, and at least one hull roller. The fastener has a locking part that extends through the rail slot into the internal rail recess for locking engagement to the rail at any desired location. A stabilizer part on the bracket cooperatives with the slot to maintain alignment of the bracket on the rail.
Abstract:
A floating low profile watercraft lifting apparatus comprises a buoyant support apparatus and a watercraft lift attached to the buoyant support apparatus. Embodiments of the lift have first and second cantilever arms pivotally mounted to a base at offset pivot points for use in shallow water. The lift includes an actuator connected to the first and second cantilever arms and operable to move the first and second cantilever arms between a collapsed configuration and an extended configuration with uniform application of force and a minimum amount of travel of actuator components. The support apparatus comprises inflatable pontoons within a frame attached to the lift and providing buoyant support for the lifting apparatus.
Abstract:
A portable skidway utilizes tubular skidding cylinders joined by connecting rods that encircle the ends of the cylinders and are contained within flanges. The rods align tangentially with the outer surface of the cylinders to locate such rods directly on the ground when the skidway is in use.
