Boat Tanks

The B526 gives you 16 gallons in 26 x 14 x 11 inches - weekender scale. It is the size that covers two people and two days on the hook without surrendering a whole locker, and at 19 lb empty it goes...

Eight gallons in a squarish 17.75 x 15.75 x 8.25 inch tray - the 21W is sized for the systems people forget to plan: the outdoor shower feed, the dedicated dish-rinse supply, the gray catch under a...

The 41W is the tank you buy when the space came first: 17 x 12.75 x 10 inches, 8 gallons, roughly the volume of a milk shipment. It fits standing up in a cabinet, lying down in a drawer bay, or...

Eighteen gallons of fresh water is a long weekend for two people if the galley is disciplined. The B104 is the tank for that math: a marine water molding in FDA-compliant potable polyethylene,...

Twenty-three gallons is what you order when twenty is not quite enough and twenty-five will not quite fit. The B136 exists for that specific negotiation - a marine water tank molded to a capacity the...

The Ronco Plastics B163 is 25 gallons kept deliberately low: 30 x 20 x 10 inches, a footprint that slips under bunks, cockpit soles, and camper floors where every vertical inch is contested. It comes...

Eight inches of height is all the Ronco Plastics B378 asks. This 23 gallon B-series molding spreads its capacity across a 40 x 18 x 8 inch pancake profile, sliding under floors, berths, and dinette...

The B428 spreads 36 gallons across a 46 x 36 inch panel only 6 inches tall - a true underfloor tank, wide as a sheet of ply is deep and shallow enough to live between floor joists or under a raised...

The B446 is another of Ronco's floor tanks: 24 gallons in a 44 x 26 x 6 inch slab. Six inches of height means it lives where furniture and floors already are - under a dinette, beneath a raised van...

The B449 threads 32 gallons through a 44.5 x 15.5 x 12.5 inch envelope - long, narrow, and barely a foot tall, the shape that follows a hull side, runs outboard of an engine, or slides down the...

The B112 is 30 gallons of marine tankage built like a fitting on a commercial hull: 91 lb empty, a wall you can rap with a knuckle and hear the thickness. Ronco molds light tanks and heavy tanks, and...
