My plan is to sodablast off the 30 years of bottom paint and the 4 coats of house paint used above the water line.
I'd recommend that you use a chemical striper on it. The house paint should come off fairly easy.The sodablasting is going to cut into the gellcoat.
Check to see if your security settings are too high and blocking it.
