The Ronco Plastics B176 is a 45 gallon marine fresh water tank, and its 117 lb ship weight tells you something before the spec sheet does: this is a substantial molding, built for the permanent, load-bearing end of the water system rather than the removable end. Forty-five gallons is passage-scale capacity - days of autonomy for a cruising crew - in one seamless piece of FDA-compliant polyethylene from Ronco's Tustin, California plant, molding marine tanks since 1974.
A tank this committed deserves deliberate plumbing, and Ronco's per-order fitting installation provides it: spin-welded or threaded ports at the exact locations you mark. Set the pickup where the tank runs dry under sailing trim, the vent where heel cannot flood it, the fill under the deck plate you already own. Print the dimensioned drawing below, plan against the real compartment, and commit the layout in the fitting planner on this page.
Full, the B176 holds about 375 lb of water on top of its own shell - a mass to engineer for, with continuous bottom support and through-bolted restraint, and a mass to exploit, placed low where it steadies the boat. Compare the other large moldings at boat tanks, survey the line at the Ronco Plastics hub, and quote the ship to your ZIP at the freight estimator.
