The foldable ramp is intended to store, carry and launch relatively large size tube-launched missiles typically on board of relatively small sized naval surface ships. Accordingly, the foldable ramp comprises a frame suitable for carrying one or more canisters for launching rockets or missiles and support elements, which are pivotably attached to the frame and which are adapted to pivotably connect to the launching platform so as to allow rotary movement of the frame with respect to the launching platform. A lifting device lifts the front end of the frame whereby the rear end of the canisters displace a horizontal distance towards the rear of the ramp as said lifting device lifts the frame. Adverse effects of the aft flame of the launched rocket or missile is securely displaced to the outside of the vehicle while foldability of the ramp enables to prevent or reduce radar and eye visibility of the launcher, particularly when mounted on a naval surface ship.

An improved float tube arrangement for outdoor water-related activities, particularly hunting and fishing. The float can be deployed as a blind for partially concealing and camouflaging a user, who sits in the circular middle of the float upon an adjustable seat supported by suitable straps. When used as a blind a canopy and net are selectively deployed. The stable base is formed by a pair of coaxially stacked inner tubes that are tightly bound by a covering fabric. Mechanical integrity is enhanced by frame loops encircling the inner tubes, and an encircling belt that concentrically tensions the float within a depressed region formed at the juncture of the stacked inner tubes. A canopy mounted to the frame loops and an optional net can be deployed as desired.

The present invention discloses an amphibious vehicle for transiting deep or shallow waters and/or the full range of wetland and dry soil environments, consists of a box-like structure with buoyant tracks that are powered to move around the structure. The buoyant tracks encircle the vehicle's length and extend laterally for a substantial portion of the vehicle's width or beam. When operating in water the buoyant tracks provide a majority of the buoyancy keeping the box-like structure above water surface or its tracks can be flooded to submerge the vessel. The amphibious vehicle can transport heavy equipment and personnel from ships located offshore, across undeveloped beaches, to positions ashore.

A boat accessory rack has a frame typically including at least two members, one of which is movable. An actuation device such as a manually operated actuator, a hydraulically operated actuator or a pneumatically operated actuator applies an actuation force to the movable member thereby moving the movable member from an unclosed position into a closed position in which the wakeboard is secured. A releasable locking mechanism such as a ratcheting mechanism, an interlocking ring mechanism, a ball bearing system or an over-centering system maintains the movable member in the closed position until a user desires to remove the wakeboard from the rack. Also, a cam mechanism transfers the actuation force to the movable member in some embodiments. In other embodiments, the accessory is secured between a rotating wedge mechanism and a second member.
