I am glad I read this forum while I am building my latest boat. I had just put the fill coat on the inside of my hull, and was about to call it a night. I remember this thread and put the deck on to check for warping. Sure enough, the hull had curled an inch or two while I had the outside glassed and the inside raw wood. No big deal while the inside glass was still curing, as I just popped in a few of the forms and it straightened right out. If the glass had setup with the deck off by a few inches, this would have been a much bigger deal.
