One hundred gallons of fresh water is the point where a boat stops planning around water and simply has it. The Ronco Plastics B313 delivers that threshold in a single large marine molding - 134 lb of heavy-walled polyethylene that, once filled, holds back about 834 lb of water. Installations at this scale are structural projects: land the tank low and centered on framing that ties into the hull, and treat the mounting as seriously as the plumbing.
Ronco builds the fitting layout to your order rather than to a template, spin-welding or threading each fitting at the locations you mark. On a tank this large that usually means a pump pickup at the true low point, a wide deck fill for fast loading, a high-looped vent, and often a second pickup for redundancy - all of which the on-page fitting planner will help you place. Print the drawing below, draw your system over it, and lock the spec before ordering. FDA-grade polyethylene keeps the full hundred potable.
Molded in Tustin, California by Ronco Plastics, at this trade since 1974, the B313 crowns the capacity chart of our boat tanks. A tank this size ships by freight - the freight cost estimator quotes your ZIP up front - and the Ronco Plastics catalog holds every smaller companion. OneSource Plastics is an authorized Ronco Plastics dealer.
