I've been reading this forum off and on for years. I recently acquired a 1925 Nat. Herreshoff s-boat (28 ft, deep keel). Lulworth, in case you're wondering, was the original name (you can see it as an entry in the list of s-boats in LHF's book on capt Nat.) The thing has been in storage for 10 years but a reputable builder was hired before it was put away to reframe it before storage -- so its still got a resonable shape. The first job is (of course) the most daunting -- I've got to replace a split aft keel(son). The keel timber in question is to be white oak (as original) and is 15 ft long, 2" thick and 12" wide (at the widest point). There is some bending to be done at least in the forward section. The plan is to drop the ballast (a whole different can of worms), replace the after keel up to the original butt joint. My question is, how seasoned do I want this hunk of wood? The butt joint now, after 10 years in storage, is remarkably tight so I am inclinded to believe that the original timber was quite dry when installed. On the other hand, when the timber gets wet (after the 3 to 5 year long rebuild, it will be bone dry) it will swell (check me on this) up to 0.25" per foot. The advice I've gotten from the local experts is to use "kinda seasoned" oak. Any other bets?
