Ronco Marine Water Tanks

Seventy-four inches long, 10 inches wide, 9 inches tall. The B515 is a keel-run tank: it lays 26 gallons down the centerline of a hull, in the dead space alongside stringers where no boxy tank could...

Size a water tank by crew-days, not by the biggest number that fits: at sensible washing-and-drinking use, the B170's 28 gallons covers a couple for a long weekend with margin. It is one of Ronco's...

The B479 lands on a tidy coincidence: 33 gallons of capacity in a 33 lb molding - almost exactly a pound of tank per gallon carried. That ratio marks it as the balanced member of Ronco's marine...

The BOAT53W is the longest of Ronco's shallow marine planks: 70 inches end to end, 16 wide, 8 tall, holding 38 gallons. Nothing else in the series covers this much length at this little height, which...

The Ronco Plastics B491 fits 48 gallons into a 39 x 27.5 x 11.75 inch envelope, under a foot tall. That geometry targets the platform-and-plinth installs, under berths, under dinette seating, under...

Nine inches tall and nearly square, the 36W is the pallet-tile of Ronco's line: 16 gallons in a 23 x 21 x 9 inch footprint that covers floor area instead of climbing walls. That geometry belongs...

The B545 holds 53 gallons in 30 x 22 x 20.5 inches - a dense, deep-bodied molding that gets serious capacity out of a compartment barely 30 inches on its longest side. Among the mid-size B-series...

The Ronco Plastics B405 is a 30 gallon B-series molding at 34 lb shipping weight, the light, easy-handling take on a capacity that anchors many small-boat and camper water systems. Thirty gallons...

The B413 is a 28 gallon example of the idea that runs through Ronco's whole marine B-series: one rotomolded polyethylene shell that becomes either a fresh water tank or a gray/black waste holding...

The B415 puts 28 gallons in a noticeably heavy shell - the bare blank weighs 91 lb, which tells you how much polyethylene Ronco puts into this particular mold. Wall mass is what you want in a tank...

At 34 lb bare, the B457 is a 30 gallon tank you can carry aboard under one arm - the light-shell counterpart to Ronco's armored 30 gallon molding. It suits protected installations: a dry locker, a...

The B459 rounds out the marine B-series at 27 gallons in a light 37 lb shell - an easy-handling tank for coastal cruisers and trailer boats where water capacity in the twenties covers a long weekend...
