It's my understanding that at least a portion of the hull was balsa cored. That's from memory but have no first person experience with the boat. Would want a definitive answer if a cored hull will make a difference to you.
Some T41's had issues with core rot
in the decks. If this boat is one of them, would want them to pay me to take the shell off their hands. The time and money
to take care of the deck issues would be way more than a gutted hull without the rig and rudder
would be worth.
