They left it in the slings barely in the water for a week before they put it in a slip. When I got home it was bilging every hour. I was scared to death. The boat yard owner that did the work said not to worry that it would swell and seal. It took about 2 months and a lot of sleepless nights before that happened. Now it seems to be pretty much sealed.
The boat yard owner is pretty darn knowledgable, leaving it in the slings
in the water for a week to allow the wood to re-absorb and swell back up.
