Removing the floor
The original plan was to just replace the deck... however I discovered that just like home rennovations, boat rennovations tend to spread beyond the original plan as well!
After removing the deck from the boat, I noticed that the fibre glass floor at the back of the boat was bubbling up a bit and was soft to the touch. I did not think that this was a good thing so I cut it open.

To my suprise the wood was like sawdust and it was damp! 10 years living under a tarp and there was still water trapped under the floor! Anyways, I ended up removing the back 8 feet of the floor... right up to where the center board goes through the hull.

This also exposed the "stiff" board that runs down the center of the boat to help the hull keep its shape. That board needed to be removed as well since it was completely rotted out and had separated from the hull. (Which explains why the boat hull was concave where the trailer applied pressure to the bottom)
Once the floor was out, I removed the foam. There were two types of foam in the floor. A sprayed in high density foam and some lighter wieght standard styrofoam.

Once I got all that out, I brushed the fibre glass to clean out all the debris. I also had to grind down the fibre glass that used to be holding the keel in place as well as remove the screws that were coming through the hull into the keel. (There was a metal strip down the center of the hull that was screwed into the keel)
The back of the boat was now ready for a new floor to be put in.
