Dagger board - DOH. I forgot the thing had them.
OK, correct me if I'm wrong. Colin is talking about cutting out the bad section. Using the good hull as a form for making a large patch. Then glassing in the newly formed patch on the cut out section. Jake, are you talking about putting in access port in the deck, in front of the center bulkhead so as to be able to push down on the compressed area from the inside of the hull? The bottom feels quite hard. Will it push down very far? How close to the original form of the hull bottom will it go?

Best regards,
Mike
