What about maintenance of the hull and hinges?
Almost no maintenance is required. It never needs painting! Why? The color goes thru and thru every molecule. You couldn't rub it off even if you tried. If it gets dirty just wash it off with mild soap and water. Almost nothing sticks to it. You won't be spending your time cleaning and "rubbing", just having fun, boating!
