A guy here in VA also has a small strip of Rhino Liner sprayed right across the top of the gunwale in that same spot on his 388 Hustler. I know it 'sounds' ridiculous, but it works perfectly, surprisingly does not get too hot, and blends right in with his dark blue paint in that area.
I put one of those on my center console between the 1/4 canopies to step out of the cockpit and onto the deck. It works great and no one ever asks me where should they step while I am busy docking!
