Rich I have owned this same boat and it was great to hunt out of. When looking at these photos it appears as if the seats have been removed and an upright added mid ship to support the combing. This may not be a big deal but the seats not only added to the rigidness but also held the floatation foam until someone remove it on my boat.
The only place you should have a wood is in the transom the rest of the boat should be glassed and very thick (5/8 of an inch). This is a very rugged boat and handles the water well. My was sold to a friend, boat, motor (40 hp ) and trailer for $1500. which I thought was a fair price. It was from the early 70s (1972) and is still on the water with a 25 hp on it. If you can do fiberglass work it should last you forever as long as someone hasn't butchered it beyond repair.
