If it doesn't come out, I'll often find a way that it will so that work can done in a shop or on the ground. You should see the great lengths they go to at the local boat builders to eliminate that enormous time sucking gap between a shop and the area below, in a boat, where the work will ultimately end up. Shops at deck level, shops on deck and shops below deck. But mostly, they've devised ways to do the more work, off the boat.
