Boat Tanks

Six inches. That is the entire height of the Ronco Plastics B406, a 60 x 21 x 6 inch molding that still finds 26 gallons by running five feet long. It is the tank for spaces everyone else writes off:...

At 40 x 20 x 10 inches the B424 is a genuine under-bunk tank: 30 gallons spread low and flat so the mattress platform above it barely notices. Ten inches of height is the dimension that matters here...

Some tanks fight the bay; the B437 is shaped for the bay most boats and coaches actually have. At 36 x 18 x 12 inches its 28 gallons ride in the classic double-square proportion - twice as long as...

Eight inches tall. That single dimension defines the Ronco Plastics B480, a 19 gallon dual-role tank spread across a 29 x 23 x 8 inch pancake footprint. It slides under berths, under RV floors, under...

The Ronco Plastics B486 is an 18 gallon dual-role tank with a noticeably stout 43 lb build, more wall than its capacity strictly requires, which is precisely what you want when the tank lives...

Nobody sets out to buy a 28 gallon tank. They set out to buy 30, discover the compartment will not take it, resign themselves to 20, and then find that Ronco molds the in-between. The B206 exists...

The B222 spreads 40 gallons into a 42 x 26.75 x 9.5 inch slab, and that 9.5 inch height is its entire argument. Underfloor bays, shallow bilge flats, and the space beneath RV galleys rarely offer...

Every boatyard has the story: the perfect tank that could not make the turn at the bottom of the companionway. The B228 is a 30 gallon marine fresh water molding whose proportions exist for exactly...

The Ronco Plastics B305 is a 40-gallon dual-purpose molding stretched long and shallow - 54" x 20" x 9" - to ride under floors and berths where headroom is the scarce commodity. Marine or RV, fresh...
