Patent number: 7815476Abstract: An amphibious utility trailer to haul a load over land and/or to ferry a motorized vehicle over water. The trailer is adapted to receive marine propulsive power and/steering control from wheel torque and/or steering mechanism of a vehicle, such as an ATV. A propulsor such as a paddle wheel, propeller, or water jet propels the trailer through water when engaged with ATV wheel torque. A friction coupling such as a treadmill or set of rollers in the trailer bed removably interconnects the propulsor with ATV tires. The trailer may also include a rudder operable through a removable coupling with the ATV handlebars to steer the trailer in water. The arrangement enables the trailer to be “driven” over water utilizing the ATV and yet still provide a plain and simple utility trailer for hauling traditional items over land.Type: GrantFiled: March 26, 2007Date of Patent: October 19, 2010Inventor: Clyde M.

Patent number: 7765947Abstract: A configuration for the deck of a marine vessel, wherein parallel and perpendicular travel paths, for movement of individual OBS unit storage baskets, are formed along a deck utilizing, in part, the storage baskets themselves. A portion of the deck is divided into a grid defined by a series of low-to-the-deck perpendicular and parallel rails and each square in the grid is configured to hold an OBS unit storage basket. Around the perimeter of the grid is an external containment wall which has a greater height than the rails. Storage baskets seated within the grid are configured to selectively form internal containment walls. Opposing internal and external containment walls define travel paths along which a storage basket can be moved utilizing a low, overhead gantry. A basket need only be lifted a minimal height above the deck in order to be moved along a path. The containment walls and the deck itself constraining uncontrolled swinging of baskets, even in onerous weather or sea conditions.Type: GrantFiled: September 7, 2007Date of Patent: August 3, 2010Assignee: Fairfield Industries IncorporatedInventors: James N.
