The BOAT6W runs 48.38 x 14.38 x 13.25 inches - four feet long and barely more than a foot wide - which is the shape of a settee base, a keel run, or the gap outboard of an engine stringer. It is how you put 35 gallons of fresh water into a boat that has length to give and beam it will not surrender.
Long, narrow tanks reward end-thinking: water surging fore-and-aft in a four-foot run has momentum, so mount it snug against structure at both ends and plumb the pickup at the end that stays low at rest. The heavy-duty shell weighs 70 lb as a blank and carries about 292 lb of contents at full - FDA-compliant potable polyethylene, fresh water service only.
Every fitting is installed per order at the Tustin, California plant, spin-welded or threaded to your marks, as Ronco has done since 1974. Print the drawing below, decide which end drains, and enter the layout in the on-page fitting planner.
