The novel bladder systems and tie down systems set forth herein provide systems and apparatuses that mitigate or prevent damage, such as tipping over/capsizing, of a watercraft stored on shore or an aircraft secured to a ground surface during adverse wind, rising water, or storm events. Further, novel apparatuses and methods for storing a watercraft using the bladders as cushioning or holding devices when installed within a cavity, whether the cavity is created by digging a hole or building an enclosing berm, provides additional stability and security for the watercraft during adverse wind, rising water, or storm events.

An object of this invention is to prevent the collapse of structures such as boat lifts, where the collapse is caused by corrosion of metal fasteners inside conductive material such as moist wood in the presence of ground voltage differences, and where the corrosion is prevented by blocking current from flowing through the fasteners.

A boat lift includes four posts and four linear actuators, each attached to one of the posts. Each linear actuator includes an extendable and retractable member oriented for extension and retraction substantially parallel to the post. Ends of a first pair of the extendable and retractable members are connected to a first carrier and ends of a second pair of the extendable and retractable members are connected to a second carrier. A cradle or platform is supported by the first and second carriers. The boat lift may be supported by the ground, by a structure, for example, a dock, a sea wall or a wall of a boat house, or by pontoons.

A tilting canopy has a canopy frame, at least one actuator, a plurality of canopy supports, and a support frame. The canopy frame is hingedly connected to the support frame through two medial supports, such that the medial supports act as pivot points for the canopy frame. The at least one actuator is engaged between the canopy frame and the support frame such that the at least one actuator is configured to rotate the canopy frame about the pivot point between a lowered position and a raised position. In the raised position, a user may store a boat or other vehicle or item with towers, Bimini tops, or other features which would normally be prohibitive of moving the boat or other vehicle beneath the canopy.

An alignment guide for a pontoon boat lift that includes a pair of laterally spaced rails, where the spacing corresponds to the spacing between the pontoon floats. The rails are attached to the boat lift by adjustable brackets, so they are positioned at an elevation above the waterline of the pontoon floats, and below the deck that is supported by the floats. A stop bar is positioned at an elevation above the boat motor and extends between rail extensions that are directed downwardly and rearwardly from the spaced rails. The alignment guide functions to provide support under the deck of the pontoon boat, to limit movement of the craft from port and starboard, and to stop the craft when it has advanced to the full forward position to keep it properly positioned bow to stern.

An object of this invention is to prevent the collapse of structures such as boat lifts, where the collapse is caused by corrosion of metal fasteners inside conductive material such as moist wood in the presence of external voltage differences, and where the corrosion is prevented by blocking current from flowing through the fasteners.
