Boat Tanks

Thirty-eight inches long, 8.12 inches tall: the 20W is a plank of a tank. It runs 17 gallons out along a chassis rail or under a bunk in a strip 15.5 inches wide, thin enough to disappear beneath a...

Under eight inches tall. The 72W closes out the slice at 35 x 19 x 7.75 inches, putting 19 gallons into one of the thinnest profiles Ronco molds. This is the tank for the layer nobody sees: between a...

The 60W is the crossover big tank: 58 gallons at 44 x 22 x 15.5 inches, cataloged for RV and marine service in the same breath. Coach builders stand it in a basement bay; boatbuilders lay it beneath...

Forty-two gallons in a 46 x 18 x 13 inch package makes the Ronco Plastics B182 the big tank for long, shallow spaces - bilge runs, under-berth channels, the full length of an RV storage bay. It is...

Nearly five feet of tank, barely more than a foot wide: the B240 stretches 58 x 13.75 x 12 inches, one of the longest slender moldings in Ronco's marine book. That geometry is a gift to sailboats and...

Most 40 gallon tanks buy their capacity with length. The B252 buys it with height instead: 26.5 x 21.25 x 18 inches, a compact block that fits where the long slabs cannot - a deep cockpit locker, a...

Narrow spaces get their own tank: the Ronco Plastics B312 runs 72" x 15" x 13", a six-foot rail of a molding that carries 53 gallons along a keel line, a chassis frame run, or the slot behind a rear...

Nine inches of height is the whole story of the B346. Its 38 gallons spread across a 37 x 28 inch footprint precisely so the tank can hide under a V-berth, beneath a dinette, or in the underfloor bay...

A perfect 32 x 32 inch square, nine and a quarter inches tall: the Ronco Plastics B383 is a 36 gallon pancake built for square hatches and center-bay floors where a rectangular tank wastes corners...

The B432 packs 40 gallons into a 28 x 23 x 16 inch block - the compact-footprint answer when your bay is short but has some height to work with. Where the long slim tanks in this series chase length,...

Fifty-five gallons under 15 inches of height: the B528 spreads its volume across a footprint just over 34 inches long by 28.5 inches wide, so serious capacity fits where a tall tank never could. This...

Forty-five gallons is the capacity that turns a coastal boat into a passagemaker on paper - enough fresh water to stop planning stops around taps. The Ronco Plastics B155 packages it in a one-piece...
