Awesome Top on the Concept. You just gave me a brilliant idea for the boat I just bought (11'6" to top of arch - 11'-0" garage door opening...)
Can you post a few pics of how that secures when folded "up"? Do you experience any rattling or looseness???
Look at pics of some wakeboarding boats. My Mastercraft X1 tower folds down and is very secure when up with zero rattles....it's buried in an ice storm right now so I can't get you any pics.
