The Ronco Plastics B301 is a 40-gallon marine fresh water tank in a long, narrow format built to lie along a hull run or chase a keel line - the shape for boats whose storage is measured in length, not lockers. It is a heavily built molding at 105 lb empty, with thick walls that stay stiff over an imperfectly supported span; full, it adds about 334 lb of water to the structure beneath it.
No fittings come pre-installed, because Ronco fits each tank per order: spin-weld or threaded, positioned to your marks. On a long tank the difference between a port at the right end and the wrong end is an extra six feet of hose in a space that has none, so print the drawing below, mark your fill, outlet and vent where your plumbing actually lives, and confirm the whole layout with the on-page fitting planner. The polyethylene is FDA-grade throughout - the supply stays potable.
Molded in Tustin, California by Ronco Plastics, marine tank specialists since 1974, the B301 runs with the low-profile crowd on our boat tanks shelf. The complete Ronco Plastics catalog is worth a scan if your run is shorter or your beam wider than this molding assumes. OneSource Plastics is an authorized Ronco Plastics dealer.
