One of the BEST Bait Tanks on the market, Custom Short 23 gallon with Base Plate 

The Short 23 gallon X-Treme Bait Tank (30 gallons total) measures 32"x24"x18" tall. This tank features a lower 3/4" drain, black inside walls, 1-12v & 1-110v pump. Use your 12v while fishing and switch over to the 110v pump once you get back to the dock. The 110v will give your 12v a rest while taking care of your bait. Wake up to bait looking better than when you put them in there and batteries charged. The Base Plate is a way to completely secure your tank to the deck of your boat and you can use existing holes in your deck to mount the plate.
