A cover system for protecting boats, vessels, and other various shaped vehicles and objects is disclosed. A plurality of separate and distinct inflatable bladders supports a cover whereby a dome-like shape is produced. The resulting shape of the cover resists pooling of water and snow thereby reducing or even eliminating water damage to the underlying structure. Furthermore, since each bladder is separate and distinct, the plurality of bladders creates a support structure that conforms to objects of various shapes and sizes.
