Boat Tanks

Seven and a half inches. That is all the height the 37W asks, and it is the least of any tank near its size in the line - 14 gallons stretched across 29.75 x 16 inches of floor. This is the tank for...

At 30 x 16.5 x 16 inches, the B127 is proportioned like a bench seat base - which is often exactly where it ends up. This 32-gallon dual-role molding serves marine and RV installs alike: settee...

The Ronco Plastics B141 carries 32 gallons of fresh water, which is real cruising range: washing up, cooking, and drinking for a crew across a long weekend without rationing. On a water tank that...

Ten inches tall. That single dimension is why the Ronco Plastics B147 exists: a 35 gallon tank spread across a 48 x 17 x 10 inch footprint slides under berths, cockpit soles, and RV floors that no...

Water is ballast whether you plan it or not. A 30 gallon tank like the B202 carries about 250 lb when full - 8.34 lb per gallon, every gallon - and where that quarter-ton sits changes how the boat...

The B239 is built for the space every boat has and no tank fits: the long, narrow channel between stringers. At 48 x 14 x 10 inches it runs four feet down the hull while staying just 14 inches wide,...

The Ronco Plastics B309 is a 40-gallon marine molding in balanced proportions - 39" x 18" x 14" - that fits where neither a cube nor a pancake will: alongside an engine bay, under a quarter berth,...

The Ronco Plastics B409 runs five feet long and seven inches tall: a 60 x 22 x 7 inch molding holding 33 gallons in space most builders treat as dead. Slide it under a floor or berth and reclaim real...

Eight inches. That is the entire height of the B529, and it still holds 34 gallons by running 44 inches long and 25 inches wide. Ronco molds a lot of low tanks; this is one of the lowest usable ones...

The B542 has a perfectly square 21.25 x 21.25 inch footprint, stands 13.5 inches, and holds 24 gallons. Square tanks are underrated: they fit hatches and lockers that were themselves framed square,...

At 8.25 inches tall, the 14W is a tank you install under things - under a bed platform, under a dinette, under the floor of a van where headroom is measured in fractions. The 24 x 15.5 inch footprint...
