Wow!
I'm with TJK on this one. You're braver than I am.
About the only piece of advice I can give you, seriously, is to make sure you have lots of bilge
pumps ready when you splash her. Back in the 70's, I helped a friend restore a 1925 Block Island Cutter. She was on the hard for nearly two years, and when we splashed her, she shipped gallons and gallons of water for several days until the hull swelled back up. We had a couple of the biggest
pumps Rule made in those days hooked up with hoses that just ran out of the companionway and over the side, and they ran just about non-stop for two days. I honestly thought she was going to sink during the first eight hours. Needless to say, we had a big
battery charger going to keep the batteries full, and that first night was a very nervous one.
