Abstract: This a system for attaching a weather proof cover on to a boat that has protection for its interior. The cover assembly has a male/female connections that seals in a rubberized channel to make it weather tight. This improved cover attaches in four-piece assembly that slides on to the boat depending on boat specifications. All pieces of cover should be attached in there proper position. Holes on the lip of each panel should lined up in order to insert the thumb screws needed to hold down the cover in all four pieces. This design uses the boat's gunwales underside to hold each piece down before anyone can insert the screws. The profile of the hard top shell is custom designed to the shape of the boat for weatherized protection.
