Forty gallons is where a boat's water system changes character - from something you monitor to something you mostly forget. Showers happen. Dishes get properly rinsed. The Ronco Plastics B150 delivers that capacity in a single polyethylene molding, FDA compliant for potable duty, from the Tustin, California shop that has molded marine tanks since 1974. Among Ronco's fresh water shapes it sits near the top of the range, sized for genuine cruising rather than day trips.
Capacity this size makes fitting placement strategic. Ronco installs fittings per order - spin-welded or threaded, at your locations - so the pickup can sit at the tank's low point under your boat's real trim, the vent can run high enough to never burp water, and the fill can land under the deck plate you already have. Print the drawing below, mark it, and lock the layout with the fitting planner on this page.
Respect the mass: the tank ships at 97 lb, and 40 gallons of water adds about 334 lb more. That is crew-weight territory, permanently installed, so frame the platform and strapping like structure. Positioned low and amidships, it is ballast that pays for itself. Compare against the rest of the boat tank line, browse the Ronco Plastics hub, and quote shipping with the freight estimator.
