Standard thing to do before launch: Painting anti-fouling.
Well.. actually not for me, since my last small boat had so many layers of paint on the bottom when I bought it that I just grinded some old off each spring, instead of putting new on. And the large yacht I had before that was repainted on Trinidad. God knows what paint they used, but it lasted forever and didn’t need any cleaning or repainting. Must have been horribly poisonous. Now we are using legal and nice paint.
Tomorrow night we are going to try mounting the keel. Don’t miss that!
