The BOAT69W is the wide plank of Ronco's shallow marine series: 48 x 20 inches of footprint at just 8 inches tall, holding 32 gallons. Where its narrow siblings thread between stringers, this one blankets an open under-sole bay - the broad, flat void beneath a center console deck or a cruiser's cockpit - and turns it into a month of drinking water.
It is a heavy-duty molding with the thick H.D. wall, in FDA-compliant polyethylene rated for potable use, from Ronco's Tustin, California plant - rotomolding since 1974. Fittings are installed per order at your marked points, spin-welded or threaded: print the drawing below and use the fitting planner on this page. On a wide shallow tank, think about where the pickup sits relative to the boat's running trim.
Full weight is about 267 lb spread across the broad bottom, an easy ask for any continuous deck.
