A movable device for alternatingly covering and uncovering a vehicle is shown and described. The device includes a protective cover, a structural member, a lift member, and an inlet for receiving a pressurized fluid and controlling the fluid to raise and lower the cover. The protective cover is constructed to receive at least a portion of the vehicle, such as a boat or a car. The structural member has an elongated hollow extending at least partially from a first end to a bottom end and ending at a termination point. A first end of the lift member is coupled to the protective cover and a second end of the lift member is reciprocally engaged with the hollow. The lift member can move with the protective cover between a first position in which the protective cover receives at least a portion of the vehicle and a second position in which the protective cover is separated from the vehicle. The space between the second end of the lift member and the termination point of the hollow defines a chamber. The inlet communicates with a source of pressurized fluid and the chamber and controls the pressurized fluid to move the lift member between the first position and the second position.
