I'm looking to buy two coolers to place behind the helm seats on port and starboard that will also serve as seating while running and trolling. I will post a pic later to show this better. My question is what to buy. The two seats aren't equal in size so I will need two different length coolers but they will be uniform in height. I will use these for storing perishables when cruising so they will need to keep food cold for 3/4 days. Are Yeti's worth the price?
