Same 31 gallons as its long-format siblings, different geometry: the BOAT26W is a squat 31 x 23 x 11.5 inch block for spaces that are wide rather than long - under a V-berth, in a mid-cabin locker, beneath a deck hatch. Choosing between two tanks of equal capacity is really choosing which cavity in your boat you want to give up, and this is the wide-cavity answer.
As an H.D. molding it wears Ronco's heavy wall, the marine-grade step up from the standard light-duty shells, in FDA-compliant polyethylene rated for potable water. Molded in Tustin, California, where Ronco has been rotomolding since 1974. Fittings go in per order - spin-welded or threaded wherever you mark them - so print the drawing below, use the on-page fitting planner to place your connections, and the tank ships ready for hose.
Full, it carries about 259 lb, low and centered thanks to the 11.5-inch height. Look at the longer 31-gallon layouts and everything else in boat tanks, or start from the Ronco Plastics hub to see the whole family at once. OneSource Plastics is an authorized Ronco Plastics dealer.
