Ronco Marine Water Tanks

Under seven inches tall and two feet long, the B270 slides 8 gallons into spaces most people write off as trim voids: 24 x 12.25 x 6.88 inches of low, flat molding for under a step, beneath a berth's...

Nine gallons in a shoebox: the Ronco Plastics B321 measures 18" x 12.5" x 11", a marine molding compact enough to claim the last odd corner of a console, cuddy or camper cabinet. It is a dual-purpose...

The B358 fits 9 gallons into 19.5 x 14 x 8 inches - shoebox proportions that make it one of the most placeable tanks Ronco molds. Eight inches of height slips under dinette seats and berth flats; the...

The B360 is a tank shaped like a duffel bag: 23.5 inches long, 10 wide, 8.5 tall, 8 gallons. That slim rectangular section is made for the gaps every build has and no catalog anticipates - along a...

The B361 stretches 9 gallons along a 25.5 x 10.5 x 8.5 inch molding - a longer, narrower take on the small-tank problem than its shoebox siblings. The extra length is the useful part: it rides flat...

Under ten inches tall, the B264 carries 15 gallons in a 22 x 17 x 9.88 inch low-profile molding - the shape for under-seat and under-berth spaces where height is the scarce dimension. It spreads its...

The BOAT21W is Ronco's heavy-duty answer to the awkward little locker: 8 gallons in a nearly square 17.75 x 15.75 inch footprint that stands just 8.25 inches tall. Squarish tanks like this are easy...

The smallest footprint in this stretch of the line: 17 x 12.75 inches, 10 inches tall, 8 gallons. The BOAT41W is the tank for the boat that has exactly one spot left - a console base, a cuddy corner,...

The B255 has the tidiest arithmetic in Ronco's marine line: 12 gallons in a 17 x 17 x 11 inch square-plan molding that weighs almost exactly 100 lb full. Sixteen pounds of tank, the rest water - a...

The B262 is 13 gallons in a 15.88 x 15.12 x 14.5 inch near-cube - a marine tank sized like a milk crate, which is exactly what makes it useful. It drops into the odd cubic voids every hull has: under...

The B266 puts 13 gallons in an 18.25 x 14.38 x 13.12 inch marine molding - a hand-truck-sized tank that installs in the spaces a hull forgot it had. It is a whisker longer and lower than its...

The B274 is nearly a perfect cube: 15.62 x 15.62 x 15.12 inches holding 14 gallons. A cube is the most volume the least surface can enclose, which is why this molding carries more water per inch of...
