Does anyone know or has faced this blue Corrosion problem? if it's electrolysis, I'm not sure how this is occurring since the boat is not bonded and she's docked in the back of the house. The nearest boat in the water is at least several hundred feet away. Any help would be greatly appreciated

Mine looked the same way until I sprayed it with an anti corrosion spray. If you've ever seen a bronze statue, that's the same color. Perfectly normal, you can clean it off, or not, won't hurt anything. I cleaned mine, now it's bronze colored again. Happy sailing.
