The front hold is for the big fish/skiis/etc, the second hold is for little fish, beer, ropes, beer. they aren't bait tanks. You can use them as storage for whatever you want. probably fish, since this is a fishing site. If you put in ice, make sure you put a drain plug in the drain hole or the melted COLD WATER will simply run to the transom bilge area. Dont put water in with the live fish or the water will wind up on the deck.

dont forget to screw the plug in the hole in the transom before you launch.
have fun.
