The BOAT66W is the flagship of Ronco's heavy-duty marine water tanks: 95 gallons, the largest capacity in the series, stretched along a 67 x 22 x 16 inch run. This is the tank for the boat that leaves the dock for weeks - a sportfisher's washdown-and-galley reservoir, a passagemaker's main supply - molded as one seamless piece with no baffled welds to fail.
The H.D. wall is at its heaviest duty here, in FDA-compliant polyethylene rated for drinking water, rotomolded in Tustin, California by the shop that has been doing exactly this since 1974. Fittings are installed per order at the locations you mark, spin-welded or threaded. Print the drawing below and plan the layout with the on-page fitting planner; across a 67-inch top deck, pickup and vent placement decide how the tank behaves heeled or trimmed down at the bow.
Respect the flagship number: about 792 lb of water when full, spread along nearly 6 feet. Frame it, strap it, and keep it low. If 95 gallons is more boat than you have, every smaller footprint is in boat tanks; delivery prices per ZIP on the freight cost estimator, and the whole line is on the Ronco Plastics hub.
