The YT250W Yeti Tundra 250 Cooler is your new best friend.
Going by sea? It's perfect for offshore sport or commercial fishing. It's big enough to hold wahoo, tuna, and amberjack, and the integrated tie-down slots keep your catch in place. The UV-resistant polyethylene material won't fade or crack from being in the sun all day. Or month. Or year.
Going by land? The Tundra 250 is one large cooler that lets you pile in a quartered moose, elk, or several deer, and the freezer-style gasket means your meat will stay fresh the whole trip.
