Re: Very Large Hull Indentation
It is very possible that under the extreme weight of water and/or ice, this/these area(s) gave up the ghost and that you may have some delamination in glass layers going on.
you do have several layers, your gel-coat, a matt, a roving, followed by the chopper gun, followed by a roving, then a matt. The worst part is/was the additives added to the resin ( for fast set ) made for some brittle resin batches .
I know that's not what you want to hear
