Boat Tanks

Nine gallons in a shoebox: the Ronco Plastics B321 measures 18" x 12.5" x 11", a marine molding compact enough to claim the last odd corner of a console, cuddy or camper cabinet. It is a dual-purpose...

The B358 fits 9 gallons into 19.5 x 14 x 8 inches - shoebox proportions that make it one of the most placeable tanks Ronco molds. Eight inches of height slips under dinette seats and berth flats; the...

The B360 is a tank shaped like a duffel bag: 23.5 inches long, 10 wide, 8.5 tall, 8 gallons. That slim rectangular section is made for the gaps every build has and no catalog anticipates - along a...

The B361 stretches 9 gallons along a 25.5 x 10.5 x 8.5 inch molding - a longer, narrower take on the small-tank problem than its shoebox siblings. The extra length is the useful part: it rides flat...

The B441 is a 12 gallon near-cube - 14.75 x 14.75 x 14.25 inches - which makes it one of the most position-flexible small tanks Ronco molds. A footprint barely more than a square foot slots into...

The Todd Marine 50-gallon round livewell (BW-50) is a one-piece heavy-wall rotationally molded polyethylene tank with a molded-in cover, hold-down lugs and recessed handles — ready to plumb for...

Fifteen gallons in 20 x 15 x 12 inches: the B131 is the tank you can actually find room for. Its compact brick of a footprint fits under dinette seats, in cockpit lockers, and against van wheel...

The B255 has the tidiest arithmetic in Ronco's marine line: 12 gallons in a 17 x 17 x 11 inch square-plan molding that weighs almost exactly 100 lb full. Sixteen pounds of tank, the rest water - a...

The B262 is 13 gallons in a 15.88 x 15.12 x 14.5 inch near-cube - a marine tank sized like a milk shipment, which is exactly what makes it useful. It drops into the odd cubic voids every hull has:...

Under ten inches tall, the B264 carries 15 gallons in a 22 x 17 x 9.88 inch low-profile molding - the shape for under-seat and under-berth spaces where height is the scarce dimension. It spreads its...

The B266 puts 13 gallons in an 18.25 x 14.38 x 13.12 inch marine molding - a hand-truck-sized tank that installs in the spaces a hull forgot it had. It is a whisker longer and lower than its...

The B274 is nearly a perfect cube: 15.62 x 15.62 x 15.12 inches holding 14 gallons. A cube is the most volume the least surface can enclose, which is why this molding carries more water per inch of...
