23' Casting Deck Hatch/Fish Box

[castnetcracker]

Hey Everyone, during my rebuild pretty much the only thing i did not remove was the forward fish box hatch (under casting deck) and was wondering if the original was insulated (Potter Hull). I did cutout and replace the casting deck and vaguely remember foam around the edges between the hull and hatch interior but not really sure. I built a fish box in the floor behind my leaning post but when it has 40 gallons of fish and saltwater ice slush in it she starts to get heavy and would like use the front hatch for its original purpose.
