Eight gallons of fresh water is a weekend on the hook for two people, and the Ronco Plastics B280 packages exactly that in a compact marine molding sized for small cruisers and day boats. The tank ships at 14 lb, and a full load of water adds about 67 lb - light enough that a single shelf in a console or under a settee carries it without drama. The polyethylene is FDA-grade, so the water you rinse dishes and brush teeth with stays potable.
The "without fittings" in the name is the point, not a shortcoming. Ronco molds the tank as a sealed blank and then installs spin-weld or threaded fittings wherever your plumbing needs them, so you are never stuck adapting your hose runs to someone else's port locations. Print the drawing below, mark your fill, outlet and vent positions, and the on-page fitting planner walks you through the choices before the tank goes on the bench.
Every B280 comes out of Ronco's Tustin, California plant, where the company has specialized in marine and RV water tanks since 1974. If your locker calls for a different shape, the boat tank lineup covers dozens of footprints, and the Ronco Plastics catalog holds the rest. OneSource Plastics is an authorized Ronco Plastics dealer.
