Abstract: A roof has a series of panels are positioned along roof joists such that there are upper and power panels to provide a series of air paths between the upper and associated lower panel. The upper panels are shorter in length than the lower panels so that a portion of the lower panel is exposed to create an opening for air to exit. The combination of the air paths and the exposed panels permits the free flow of air from the bottom to the top of the roof which allows cooling as well as rain water to flow along the lower panels.

The connecting unit will automatically fix its length after it has been put in place between a dock and boat, through a first tube having a valve device connecting its ends and two other tubes connecting each end to an inner location in said cylinder having a check valve preventing flow from each end to its inner location. The end of the connecting unit connected to the mooring structure provides for movement with the tide. When not in use the connecting unit can be placed in an upwardly extending position for availablity.
