Some guys I have known that ran for tuna for multiple days offshore in recreational boats used chill plates in their fish boxes to keep from losing their ice. Not sure but I think it is a bit costly to just keep the beer cold but if you are catching fish to sell then you must keep things chilled. Here's one outfit that I think makes the chill plates and the power unit. https://www.indelwebastomarine.com/us/products/marine-refrigeration-systems/
Thanks half hitch.
Saturdays trip had 52 albacore. Some folks don't realize Oregon has some great tuna fishing. It is a 12 hour day and the fish need to be cooled quickly. The fish box could be used as a chill tank, then placed in a tote. I need the best care for my clients fish.
