Re: Goiot Traditions Hatch Repair?
I don't know if your frame is cast, extruded or other, but perhaps a new ridge as you call it could be TIG or aluminum wire welded onto the frame. Or maybe a hole could be drilled and tapped for a screw/bolt that takes the place of the ridge. Welding would probably require the hatch to be removed. Installing a screw might be done on board.
The Atkins and Hoyle deck hatch on my Mirage has a little nub of Al that positions the end of the spring for tension. This is my only reference to suggest solutions for your problem.
