Ronco Marine Water Tanks

The B527 is a shallow 18-gallon tray of a tank - just over 34 inches long, roughly 15 inches wide, and only 9.5 inches deep. That last number is the reason it exists. Under a V-berth, under a cockpit...

Small boats deserve real tanks too. The B199 puts 12 gallons of fresh water capacity into a rotomolded shell that ships at just 20 lb - a size drawn for day sailors, center consoles, and pocket...

The B128 is a tube with corners: 34 x 12 x 12 inches, a foot-square section stretched nearly three feet long, carrying 22 gallons down spaces where nothing wider will pass. Keel lines, frame-rail...

The Ronco Plastics B181 spreads 20 gallons across 30 x 18 x 10.5 inches - a low, wide molding built for the horizontal gaps under berths, seats, and camper floors. It is part of Ronco's marine water...

The B200 is a crossover in the truest sense: a 20 gallon molding at 24 x 17 x 12 inches that Ronco lists for marine and RV service, as water or as waste, with the role fixed only when the fittings go...

Seven and three-quarter inches of height. That is the B211's entire vertical demand, and it is the reason this 18 gallon molding fits where tanks are not supposed to fit: under cockpit soles, beneath...

The B232 is a tank shaped like a floor joist: 48.5 x 10.75 x 8 inches, four feet long, narrower than a sheet of notebook paper, and holding 18 gallons anyway. Shapes like this are not designed at a...

A 21 x 21 inch square, 11.25 inches deep, 20 gallons: the B233 is marine tankage at its most rational. No long axis means no wrong orientation - the tank drops into a square locker or a cockpit void...

The B234 keeps 20 gallons under nine inches tall. Its 33.25 x 17 x 8.75 inch envelope is drawn for the underfloor middle ground - shallower than a locker, deeper than a chase - which happens to be...

Six inches. That is the whole vertical story of the B235, and it is the reason this tank exists: 18 gallons spread across a 40.75 x 18 x 6 inch pancake that slides under a berth, a cockpit sole, or...

The B257 packs 20 gallons into an 18.5 x 18 x 16 inch near-cube - the most compact way Ronco molds this capacity. Where its slimmer siblings trade length for a low profile, this one trades nothing...

Twenty-two gallons is more than a day tank and less than a cruiser tank - the capacity for the boat or camper that goes out for a long weekend and hates rationing. The B276 carries it in a 23 x 16.88...
