Here's what I use in the hot days of the summer. We place the minnow bucket down inside the cooler, bag of ice around the minnow bucket. It's square, doesn't tip over in the boat, has a drink holder on top, a flip top for storing smokes, lighters, etc. Plus inside the cooler has a small tray that we use to place extra grubs, weights, hooks, etc. Almost never have to leave the seats with this sitting between the two of us.
