New owner of a 2001 43' SS. The very large cockpit sole fish box was a big selling point but finding it a bit disappointing. First overnight fishing trip we used a fish bag in the box to store ice. By morning it was completely gone. These bags always hold ice for at least a day or two on the cockpit floor. I'm guessing the heat from the engine compartment and exhausts are heating the box? Was considering a large custom fish bag to fit the box but it looks like it would be wise to explore other options. Can anyone make suggestions on what they have done and are you happy with the result?
