yes the foam stations had separated from the hull sides but at different degrees and in a patchy way..... not all of them had let go and whilst a couple had completely become detatched others had only slightly let go, I also had a couple that had cracked across the actual foam and yet were still well attatched to the hull.

I think what happens is the glue at the foam/deck/hull connection area is under constant stress, weight on the deck pushes down and therefore this pushes the hull sides apart, once the glue begins to fail the foam subframes begin to compress, this inturn allows even more pressure to be placed on the hull side and so the glue continues to fail further downwards allowing even more foam compression/failure....
once the stone starts rolling effect

be interesting to see your approach.....
