Boat Tanks

Eighty gallons is boondocking currency. It is the difference between a weekend off-grid and a week, between rationing dishwater and living normally while the nearest hookup is a county away. The B230...

The B248 runs 48 x 20 x 17 inches - a four-foot bay-length tank that puts 65 gallons under an RV floor while leaving the bay's upper half free for everything else. It is the shape for coaches and...

Fifty-two gallons is a serious water budget - at 8.34 lb per gallon the B422 hauls about 434 lb when topped off, enough fresh water to keep a cruising couple off the dock for a real stretch. The...

The B471 carries 34 gallons in a 50 lb marine shell, which puts it in the sweet spot for coastal cruisers: enough water for real trips, not so much that filling it rearranges the boat's trim. Full,...
