Thirteen inches wide and 35 long, the BOAT39W is a 21-gallon molding drawn for the slot alongside an engine, the outboard face of a quarter berth, or the narrow run under a side deck. It is the middle child of Ronco's narrow-format tanks - more capacity than the true keel slivers, less beam than the berth-sized panels - and for many boats that middle is exactly right.
The H.D. wall puts it in Ronco's heavy-built marine class rather than the light-duty series, and the FDA-compliant polyethylene is rated for potable water. Molded in Tustin, California, where Ronco has run since 1974. Fittings are installed per order to your marks, spin-welded or threaded: print the drawing below, place your connections with the on-page fitting planner, and the tank arrives ready to plumb.
Budget for about 175 lb when full - an 11-inch-tall tank carries it low, but the narrow base still wants a strap. Compare narrow shapes in boat tanks, or open the full catalog at the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
