Insulating fish boxes

Unread post by ShiverMeTimbers »

Has anyone on here insulated their fish boxes? Mine melt 20lbs of ice in a few hours. I checked bloodydecks and ifish, but wondering what people have done on their Hewescrafts.

I emailed Wilderness Designs about getting custom bags made for the boxes and under the bilge, but since we may be selling the boat in the next few years to upgrade to a 270 Pacific Explorer I'm not sure I want to make that investment.

Has anyone done the cheaper mod of cutting foam and wrapping in aluminum tape? Did you install a drain for that setup so the pump can remove water from the fish boxes? Any issues with corrosion?

Thanks in advance!

I use what the commercial fishermen call ice blanket. It is very dense sheet foam purchased at commercial fishing store LFS.

There's an outfit called WPS or WIlderness Pack Systems that makes custom insulated kill bags to your measurements. They make them to fit inside fish boxes on aluminum boats... If I ever have an extra $500 laying around, I want to get 2 (one of the transom box, one for the in-floor.)

You can remove them to clean, which is way better than taping in foam sheets.

I've been tossing around the idea of using foam insulating panels, caulking the seems and spraying with something like Flex Seal. This is the kind of panel I was looking at. There are also panels with higher R-Factors and greater density.

I would worry about trapped moisture/saltwater behind the panels and corrosion. I would really want something that is removable.

I fish in Maryland and in Florida. The first time with the boat in Florida my ice would melt in about two hours (100 lbs). On return to Maryland I proceeded to insolate the outside of the box with foam board and foil tape this tripled my melt time but still was unable to insolate the outside of the box that was against hull (water side), so I insolated the inside of the box and made them removable (a must) this is the ticket, my Ice now last three days. I used 1 inch foil rapped board. Having it removable is a must to clean it out and remove the smell. I also purchased some of that foil covered plastic bubble insolation (1/4 inch thick) and made a seamless bag and is removable. you can see were I folded the corners instead of cutting them to make them neat. it looks a bit unpolished, but when ice and water is in it, the fit is real nice and holds pretty much the same amount of fish/ice as the pre-insolation did.

That's what I was looking for! Thank you Hardrocks! I think for this season that would be great. Seems like a smaller investment than getting the custom bags made.

I did not take a picture if it but I also insolated the lid the same as the box itself, and I think this really helps here on the east coast when the heat and sun are beating down on the deck. The 1/4 inch foil bubble insolation is what give it the nicer look and does not seem to get damaged like the foam board under it does without it.
