Well like i suspected.. it is definatly waterlogged! hit the plywood with a hammer went thru like butter. it is demo time...
The hard part will be deciding where to stop. I ended up taking out pretty much all the wood, including the strips embedded in the chines under tabbing and all the pads on through hull holes. Pretty much every piece of wood I took out was waterlogged.
I also found a seperation between the hull and the floatation box, (please correct me when im not using the right terminolagy)
The "flotation box" consists of a pair of stringers poorly covered with plywood. So I think you found a delamination of the stringer tabbing. I had one too, on the port side towards the bow.
here are some more pics... i have looked on youtube for some referece for lots of stuff. any advice in the demo would be great.
The pics are a bit small and hard to see. It would be better if you could post them to photobucket or similar and link them in. I post on my Google+ page and link to that.
when i seperate the hull from rotted wood and comprised fiber glass should i se a hacksaw or should i use a cutting disk
You'll probably end up using a lot of different tools
I suggest getting the tank out first. You'll need to remove the frames/bulkheads before and aft of it first. Sawzall worked well for me, but take care.
Then, take the tops of the flotation boxes off... sawzall, wrecking bar will likely be your friends.
After that... remove old wet foam
Im pretty upset i did not take the boat to be weighed. what would be and educated guess the additional weight of the boat due to waterlogged.
Likewise. I dumped 350lbs of old glass and wet wood, plus probably another 200lbs of wet foam. I doubt I'll put much more than 150lbs back in.
