SeaCraft Coring: What was used & where is it?

[GradySailfish]

I just rebuilt a 78' 20 Master Angler. There is no coring in the hull sides...just glass. It might be rather thin on the sides of the hull above the waterline to the gunnel cap. Originally they used woven roven and put carpet material over it on the inside of the boat.

Balsa coring however was used extensively throughout the boat. The deck, tank coffin cover and topcap, are cored with balsa. The transom is plywood.

On my boat the rot was so bad I had to replace all the balsa and the transom.

But the hull sides should be fine.

If you have questions, please don't hestitate to contact me. I know those MA's inside and out....literally!
