Thanks Tim. Cobia has the same layout as Amberjack. Wood strip deck, forward, back to the sail and steel clamshells aft of the sail. I'm not sure where the changeover occured, but drawings, I have, show the clamshells starting at the lead edge of the sail.
Amberjack's wood portion was raised slightly above the combing. But, as pointed out earlier, this wasn't a hard and fast rule. Some of the boats, that I served on, had it flush.
I don't suffer from ulcers, I'm a carrier.
