I'm finishing up the transom reconstruction on my '77 19-6 and I hope to splash it for the first time this weekend. I had a question about the fish box in the bow deck. Is there any, or much, insulation around the surrounding tub beneath the floor? I can add a piece of foam board on the bottom of the lid to help some but I was curious about below deck. I'm curious whether this is worth using for a fish box or should I just plan on using it for semi-dry storage?
