The 59W arrives exactly as its name says: a 60 gallon marine water tank without fittings - a bare, heavy-wall molding at 40 x 25 x 15.5 inches, waiting for your layout. For a refit or a custom hull that is the entire attraction. No pre-placed spuds to fight, no compromise port locations; every penetration goes where your plumbing plan says it goes.
The shell is molded in FDA-compliant polyethylene, so with potable fittings it serves as a boat's main fresh supply; as part of the Water / Waste Holding Tank series, the same body can instead be fitted for waste service. At 74 lb empty, the wall thickness is doing what a tank strapped inside a moving hull needs it to do.
Full, it is about 500 lb of water at 8.34 lb per gallon - ballast-grade mass that belongs low, centered, and bearing on structure, with chocks and straps rated for sea states rather than parking lots. Companion shapes for the same job are under boat tanks; land-side equivalents fill the RV water tanks category; and the freight estimator prices the empty shell to your ZIP.
Rotomolded in Tustin, California since 1974. When you are ready, fittings are installed per order - spin-weld or threaded, to your marks: print the drawing below or lay out the penetrations on the click-to-place planner. OneSource Plastics is an authorized Ronco Plastics dealer.
