: What Jay Babina said, but with a serrated blade would be easier or
: with a Japanese pull saw. Let your error be on the bench side,
: i.e. if any wood comes up let it be off the bench, and then sand
: it down being careful not to sand beyond the face of the ply.

Thanks for all the replies. It was glued to a piece of 3/4 in plywood. I used a hair dryer and first lifted off the fiberglass, then used a knife in the joints to separate them and the hair dryer and a 3 in putty knife to pry the sheets up. Worked good for the most part. Tore some small pieces of plywood off, but that will be on the inside of the 'yak and I'll fill them with dooky smutz. Another lesson learned, if I remember it the next time.
