Check my thinking on this:
Keel timbers ought to be green, so when the boat hits the water they won't swell up and cause trouble.
But how green? Can I go cut down a white oak, shape it, and start building? There's a local mill that sells wood 'about as green as it gets.' Or is it safer to let it dry at least a little bit...and how much is 'a little bit'?
And the rest of the backbone -- deadwood and stem timbers. How green should (can) they be? Again, the greenest wood is the cheapest, and if it's what I should be using anyway, there's no question.
By the way, I'm building in an unheated, un-air conditioned shed with a dirt floor in Virgina. Lots of humidity this time of year.
Any advice or thoughts?
