Ronco Marine Holding Tanks

The B347 holds 40 gallons in a 34.75 x 26 x 11 inch molding that ships at just 38 lb - a low, light, wide blank that installs like a much smaller tank and stores like a much bigger one. Eleven inches...

The Ronco Plastics B380 is a wide, shallow 42 gallon platform: 40 x 26.75 x 10 inches, built for bilge floors and basement bays where height is capped at ten inches but floor area is generous. The...

Seventy inches. The 53W is the longest of Ronco's low planks - nearly six feet of tank at 70 x 16 x 8 inches, carrying 33 gallons in a profile just eight inches tall. Tanks like this are why...

A 25-gallon dual-role tank is the most useful single molding a mid-size boat can carry, and the B115 is Ronco's: order it with fresh-water fittings and it is a potable supply tank in FDA-compliant...

The B118 is a 30-gallon dual-role tank in a 24 x 20 x 16 inch package - dimensions that read like a bay in a boat and a compartment in a camper, which is exactly the point of its marine-and-RV...

Ten inches of height is the entire design brief of the Ronco Plastics B162: 30 gallons pancaked across a 30 x 24 x 10 inch footprint so it can live under a berth, a dinette, or a raised RV floor and...

The B350 is what a compromise looks like when it is done well: 30 gallons in a 33 x 20.5 x 11 inch molding, low enough at 11 inches to slide under berths and floors, compact enough in plan to fit...

The B355 is a plank of a tank: 53.5 inches long, 16.75 wide, and just 6 inches tall, holding 21 gallons in the kind of space that exists along a keelson, beside a stringer, or under the floor channel...
