At 44 x 22 x 15.5 inches, the BOAT60W is the balanced middle of Ronco's 58-gallon marine family - not the longest, not the squarest, not the shallowest, but the set of proportions most likely to fit the tank bay a production boatbuilder actually left you. Two-to-one in plan with generous depth: measure your cavity and there is a fair chance this is the match.
It is a heavy-duty molding with Ronco's thick H.D. marine wall, in FDA-compliant polyethylene rated for potable water, made in Tustin, California - a plant that has rotomolded continuously since 1974. Fittings are installed per order wherever you mark them, spin-welded or threaded. Print the drawing below and use the on-page fitting planner to position fill, vent, pickup, and sender before you order.
Budget about 484 lb for the full tank and build its platform accordingly. If this footprint is close but not right, the other 58-gallon shapes are in boat tanks; the full catalog lives on the Ronco Plastics hub, and the freight cost estimator prices delivery to your ZIP.
