Boat Tanks

Most owners who buy the B423 are buying holding capacity, and 29 gallons is a genuinely useful black water number - enough that a family aboard for a long weekend is not rationing flushes or hunting...

That is deliberate. Ordered for fresh water duty, the food-contact polyethylene is safe for drinking water storage. Ordered for waste, the identical wall does holding-tank work without complaint...

The B564 is the B-series molding with its footprint on the label: 28.75 x 19.75 x 11 inches, 24 gallons. That 11 inch height is the story - this is a flat tank, built to disappear under a berth, a...

Refits rarely go according to the original plan, which is why the Ronco Plastics B283 is deliberately uncommitted: a 65-gallon marine molding that becomes a fresh water tank or a gray or black waste...

The Ronco Plastics B307 carries 64 gallons of fresh water in a substantial marine molding - 101 lb of thick-walled polyethylene shaped to run low against a hull. It is the tank for a cruiser...

Sixty-five gallons is serious capacity for a below-deck molding, and the B324 packs it into 37 x 30 x 15 inches - a wide, squat block that keeps its weight low in the hull instead of stacking it tall...

The Ronco Plastics B379 carries 45 gallons in a molding that ships at just 46 lb, the light-wall counterpart in a capacity class where Ronco also molds much heavier shells. If your installation is...

The Ronco Plastics B386 spreads 45 gallons across a 36 x 33 x 10 inch platform, a near-square shallow format that suits mid-cabin floors and RV basement compartments equally well. The B-series...

There are lighter 30 gallon tanks in Ronco's catalog than the B418 - this blank ships at 109 lb, and that surplus is all wall. Choose it when the tank will live somewhere unkind: against frames in a...

The B210 packs 50 gallons into a 33 x 27 x 14 inch block - a squat, broad-shouldered footprint that puts serious capacity under a berth or a dinette without demanding the long chase a low-profile...

The Ronco Plastics B376 puts 45 gallons into a 38 x 22 x 14 inch footprint, shorter and wider than the keel-run tanks of the same capacity. That proportion suits transverse mounting: across an RV...
