Boat Tanks

Three gallons. The 13W is the smallest kind of honest: a 17 x 7 x 7 inch sleeve of polyethylene for the jobs where a big tank is the wrong answer - a camper van sink, a tool-trailer handwash station,...

The B269 is a 4 gallon torpedo: 17.62 x 8.25 x 7.88 inches, longer than it is wide or tall, built for the tunnel-shaped voids behind kick panels, along chassis rails, and under gunwale edges. Where...

A 12 x 12 inch footprint. That is the entire deck space the B535 asks for, standing 13 inches tall and holding 7 gallons - the smallest footprint of any marine tank on this page. It exists for the...

Smallest is sometimes exactly right. The Ronco Plastics B303 is a 5-gallon marine fresh water tank for the jobs that do not need more: a washdown supply on a center console, a galley tank in a...

Three gallons sounds trivial until you need exactly three gallons in a space the size of a shoebox. The Ronco Plastics B377 measures 18.5 x 9.5 x 6.75 inches and exists for galley sinks, wash-down...

At 7.5 gallons and a 26 x 11 x 7 inch envelope, the B525 is a tank for boats where every locker already has a job. It slides under a cockpit sole or behind a settee, weighs 13 lb empty, and one...

The B268 is a square-plan 5 gallon molding, 12.25 x 12.25 x 8.25 inches - a tank with the footprint of a floor tile. That flexibility matters most in the cramped corners this size lives in. Five...

Three gallons is the smallest water system worth plumbing, and the B267 is its tank: 16.38 x 9 x 5.25 inches, 7 lb, a molding that fits inside a console, under a helm seat, or behind a galley kick...

A perfect cube: 12 x 12 x 12 inches, 7 gallons. The B326 is the simplest shape in the B-series and one of the most useful, because a one-foot cube is the easiest volume to find on any boat or camper...

The Ronco Plastics B404 is a 6 gallon square-footprint molding, 13.75 x 13.75 x 10 inches, shaped to occupy a single locker corner or console void. Ronco lists it for water or waste because the...

The B271 is 7 gallons in a 19.25 x 13.12 x 7.12 inch flat pack - low enough to disappear under a bunk or bench, big enough to run a small galley or head for a day. Seven gallons is the capacity where...

The B275 is the half-height companion to Ronco's small cube tanks: 15.62 x 15.12 x 7.75 inches, 7 gallons in a squat square-plan molding. Same tidy footprint as its taller siblings, half the headroom...
