Alan, I don't understand this part ...
On hull #359, there is a core about 6" wide running from the top of the stern panel to the bottom apparently to stiffen the panel at the gudgeon supports.
Do you mean there is a _balsa_ core running vertically ... or is there some additional fiberglass? If the entire hull is built in two vertical halves, then this might have just been some tabbing to reinforce the joint.
