At 7.75 inches tall, the BOAT72W is the shallowest tank in this run of Ronco's heavy-duty marine line - 20 gallons pressed into a 35 x 19 inch panel that fits where even the 8-inch planks will not. Under a lowered sole, beneath a shallow berth flat, in the last unclaimed inch-critical void on a small cruiser: this is the molding that squeezes in.
Shallow, but built to the same H.D. standard as the rest of the series - a heavy marine wall in FDA-compliant polyethylene rated for potable water, rotomolded in Tustin, California since 1974. The tank ships at 16 lb as a blank; fittings are spin-welded or thread-installed per order at the exact locations you mark. Print the drawing below and lay out your connections with the fitting planner on this page - with under 8 inches of depth, pickup placement is worth a careful minute.
Full weight is about 167 lb across the wide bottom panel, easy work for a continuous shelf. Compare every low-profile shape in boat tanks, see the light-duty range under RV water tanks, or browse the whole family at the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
