Standard in each boat, each seat has 1.4 cubic feet of foam sealed on each side (6). The centers are for storage. Seats are made of one piece front and back, tops are 13'' WIDE. The front seat will hold 36 beverage cans, 2 bottles of water and 8lbs of ice. The center seat holds the battery, light switch, 12v power supply outlet for GPS, depth finder & phone charging. The rear seat stoage is up to you. It can store the stern light pole, horn, power switch for electric start motors, anchor line, tools and mini bilge pump. Drain holes on each side for easy washdown are large enough that bottle tops won't get stuck. The port side drain at the stern is 1-1/4" and drains the boat quickly in or out of the water.
