A retractable trailer cover adapted for mounting to an existing boat trailer and a method for retrofitting the trailer cover to the boat trailer. The trailer cover includes multiple ribs extending from one side to the other, a flexible cover material, two elongated tracks, and multiple wheels received within the tracks. The ribs are affixed to the wheels so as to be slidably mounted to the tracks. Mounting brackets can be spaced along each of the trailer cover sides, and the tracks can be affixed to the mounting brackets. To mount the trailer cover to the boat trailer, the mounting brackets can be attached to a frame of the boat trailer. The trailer cover can selectively be expanded and retracted to cover and uncover an associated boat and boat trailer and may be used with new or used trailers.

Provided is a shelter floating device which enables an amphibious shelter to stably float on a surface of waters. The shelter floating device is provided on a lower surface of the amphibious shelter, and has a protruding floater, a Scott Russell mechanism unit, and a jack (operating means). The protruding floater is connected to the jack through the Scott Russell mechanism unit, while at the same time, being supported by a support device. The jack is fixed to the lower surface of the amphibious shelter. Consequently, by operating the jack, the protruding floater projects itself to an outside of side surfaces of the amphibious shelter along a perpendicular direction.

An improved boat cover for covering a boat having a strap configuration that helps to better shed precipitation. The cover may have a fabric having a top side that is adapted to shed precipitation and a bottom side that, when the boat cover is in an attached state to the boat, at least a portion of the bottom side faces a portion interior of the boat. One or more longitudinal straps and one or more lateral straps may support the fabric on its bottom side. In the attached state the straps support the fabric such that a semi-rigid rib structure beneath the boat cover is formed to pull the boat cover taut over the boat.

A trailer and boat covering combination system includes a trailer including a frame having a front end, a first lateral member and a second lateral member. A plurality of wheels is rotatably attached to and extends downwardly from the frame. A pair of supports is attached to the trailer such that each of the first and second lateral members has one of the supports attached thereto. A spindle is attached to and extends between the supports. The supports are pivotable forwardly and rearwardly relative to the trailer such that the spindle is movable over the trailer. The supports are biased toward an upright position. A covering is positioned on the spindle and is unwound off of the spindle to cover a boat positioned on the trailer. The covering is wound back onto the spindle to store the covering on the spindle.

An illustrative embodiment of an enclosed boat trailer may be configured to allow loading of a boat in the water for the purpose of removing the boat from the water using the enclosed boat trailer to engage the boat for storage and/or transportation. An illustrative embodiment of an enclosed boat trailer may be comprised of a roller system positioned on the floor and a right and left rear arm adjacent a rear opening in the enclosed boat trailer. In an illustrative method of use, a boat operator may load and/or unload the boat into the water from the enclosed boat trailer without leaving the boat and without additional personnel.

A rock guard comprises a flexible sheet of mesh selectively wound around a spool to be selectively retracted and deployed in front of a trailer or its contents, such as a boat. A pair of brackets mount to a rail of trailer and carry the spool. A top distal edge of the sheet can be flexible and arcuate in the deployed configuration to form an arc matching a gunwale of the boat.
