This is a great location to work. We still need to punch the windows in and pour a floor, but very pleasant.
The Pumpkin is quite amazing when one gets the boat back to bare wood you can see she is a tough little craft. The bad news is that there is a lot of work to get the boat usable again. It is not just ice and beating damage, there is quite a bit of "bad wood". You can see the more concerning areas in the center plank near the bow where there are holes through to inside. This can be patched, but removing planks would be very tricky.
First stage of repair inspection: http://cruising.ca/services/docs/dory.html
The bottom is now stripped and the bottom runners removed. With most of the paint is gone and the damage can be seen I am amazed at the strength of the Pumpkin, and am very pleased that the footrest braces we I installed last year, otherwise there would have been nothing but kindling as the side really took a beating.
Perhaps the larger issue is that the soft pine has begun to deteriorate quite badly in a couple of places and I doubt with the damage that replacing planks on a lapstrake hull that has tapered overlaps is cost effective as to remove and replace a plank is almost more trouble than building the boat. At this stage with everything open, the wood needs to dry further and an inspection discussion would be worthwhile as a restoration repair is not practical.
After much deliberation I believe the only salvation for the Pumpkin is to use epoxy and a single layer of fiberglass cloth to sheath the underwater area. There is a huge difference between Polyester Resin (what is commonly though of as fiberglass) and Epoxy's. Epoxy laminations are more flexible and much lighter while creating a structure that is over twice as strong. Epoxy also has the benefit of having a far reduced chance of separation. Eg. if you are going to try to break a laminated piece it will be the wood next to it that will break long before the laminated part ever will. The test patches showed no adverse reactions to any of the old material meaning a worst case adhesion coefficient would be the adhesion of any original coatings trapped by the epoxy. It is still a big job and that would use the better part of three gallons of Epoxy to do the job & cloth on top of time.

It has been a little over 48 hours since we first got the Dory stripped and begun investigations. Once again the lock of the footrest supports was key to the Pumpkins survival. The long split on port side is long enough the the bottom has begun to detach from the sides. At this time the gap is roughly 1/2" separation midships (creating the longitudinally gaps between the planks you see in the pictures of the affected area. It is only the footrest blocks that keep the bottom from springing completely loose (disaster).
The first issue of the repair will be to create a clamping jig and pull the bottom back to the sides so that we have the shape back. Then to make a temporary support jig to keep the shape fixed. Once the pieces are are epoxied back together and in the right shape with the jig secured we will turn the boat back over and begin interior repairs. Virtually every frame has been ripped loose from the floor with two frames having broken ends where they extend towards the center of the boat. These broken frames must be sistered and the cross planks secured.

Once the structural frame is restored and the bottom re-attached, it is back over again. At this time I think to concept is to go with a full size single piece of 1.5 oz cloth that wraps from the garboard (bottom plank) fto the first or second plank. Once cured give the new bottom a once over with the grinder and add 6" 1.5oz tape to the edges for strength. Ideally the object is to squeegee out the lay up cleanly enough that it may be textured, but not nasty. To a finish that is non objectionable once a paint goes on to.
With the bottom glassed it is time to flip again and finish any structural medications to the inside and epoxy / 1.5oz fiberglass patch the inside of repaired areas. There is an interesting area on the opposite side of the primary damage where what look to be a plank cracked. Yet Lo... the plank is heavily faired, with the exact extent of the crack yet uninvestigated, however it will have to have a F/G patch on the inside as well.
From here it is pulling the entire project back together and painting which is no small task. I can only suggest the one might consider a better way to protect the Pumpkin from the ravages of the reach as one more big crunch like this and she might go beyond saving.
