OK. I was hot as hell; I was wearing a full tyvek suit, dust mask, and eye goggles. I didnt realize how far back I was, to where the "V" of the hull flattens out and the stinger grooves fade away. Yes... I ground through the hull. You can't call me anything I haven't already called myself twice, and believe me I have an extensive vocabulary of less than polite words. The good news is it's a tiny hole.
