The BOAT24W stretches 31 gallons along a 43 x 16 x 10.5 inch run - the proportions of a settee base or the void behind a cockpit locker face. Long-and-low is how naval architects prefer their water: the tank hugs the hull, keeps its center of gravity near the sole, and leaves the vertical space above it for storage.
It carries Ronco's H.D. wall, thicker than the standard light-duty RV moldings and meant for offshore pounding, in FDA-compliant polyethylene rated for drinking water. Ronco has molded these in Tustin, California since 1974. The tank is a blank until you order it: fittings are spin-welded or thread-installed to the exact spots you mark, so print the drawing below and plot your fill, vent, and pickup with the fitting planner on this page.
Plan the structure before the plumbing - about 259 lb of water rides in this tank when full, spread across nearly a 4-foot length, so give it continuous bearing rather than point blocking.
