Abstract: Audio systems are housed by an enclosure with a substantially waterproof seal such that the audio systems may be mounted in outdoor locations such as decks, boat docks, and the like. The enclosure may include a panel that opens relative to a tub portion, such as by a hinged connection, and a substantially waterproof seal located there between. The audio systems may include one or more various features such as external speaker connections so that speakers may be located distantly from the enclosure. Other features may include internal amplification that may be stand-alone or integrated into an audio signal source such as a radio or compact disc player or combinational device such as an automobile head unit. Additional features may include a power supply that provides power for the amplification and/or audio source, an external cover with a substantially waterproof seal relative to the enclosure, filtered ventilation via an electric fan, and other related features.

Abstract: Foldable boat covers provide various features including a cover portion which is foldable. Other features include hinges allowing the base structure to be folded. By folding the cover portion, the base structure, or both the cover portion and base structure, the boat may be placed in a garage or on a covered boat lift with a lesser likelihood of the boat cover interfering.
