Thanks Strick I've seen your work and if you had the desire or need for a boat like this you would have built it a long time ago.
This has to be the toughest 33 year old boat I have ever disasembled. I was a little worried with the loose tabbing in the bilge but that was limited to things like the shelf the tank and batteries sat on and not the lay up of the stringers. The liner is still well stuck to the top of the stringers and most of soft spots in the deck are a result of seat mountings and holes cut through the coreing not being sealed and limited to the immediate area.
A little careful sawsall work on the foam and out the tank came.

This crack was found under the Seavette rear cap it starts where you see and only goes half way down the in side. There are two cracks on the top of the deck in this same area on both sides of the old engine well but the stingers don't show any weakness or damage. I think when they patched the rotting transom the plates transfered the fore aft torque of the engines to the combing and deck rather than the hull and stringers.
