I looked at the Yeti but haven't decided if its worth the cost.Yeti. I had an Igloo before that lived on the boat. I replaced hinges, latches, and handles over and over. When the case failed due to UV we bought a Yeti. It cost a lot but not as much as the Igloo plus all the repairs. No failures, and ice lasts 50 - 75% longer.
I've got an old ice cube that we used camping. That might fit the ticket if it will fit!When we had the 22 I bought an Igloo Ice Cube. It's more vertical than horizontal and took up less berth space. It also fit nicely in the middle of the boat between the berths for use as a table, has cup holders built into the lid, and inside trays at the top to keep stuff like the cheese and salamis and whatnot out of the way of the melting ice.
It also closes snuggly so there's no flappy thing on the outside that snaps shut. We have another cooler with a thing that snaps shut that got caught on a door or something while open and broke off. That cooler is now used only at home for parties since it won't close securely.
The Ice Cube is still my primary cooler for the boat and now used for beer to keep a certain person (who once rummaged around at night in the dark for a beer and left the steaks out on the counter in 90 degrees when he forgot to return them) out of the boat's ice box.
