Cory, I've got a black hull but I've protected it with a KeelGuard
in black. You can't tell it's on unless you are looking for it. I had the dealer install it as I did not have a good way to lift the boat with the front of the keel free. It's really tough stuff.
My last boat regularly beached on gravel shores with rocks but it did that for many years. I had repairs done once and almost all were in the area covered by the KeelGuard. The gelcoat is not as thick as a dime.
