The Ronco Plastics B188 closes out this run of the marine line the way Ronco opened it in 1974: with one more precisely-shaped answer to a compartment that off-the-shelf tanks ignore. It is a 25 gallon fresh water molding, shipping at 39 lb, in FDA-compliant polyethylene - seamless, corrosion-proof, and taste-neutral, the properties that made rotomolded tanks the default for potable water afloat.
Twenty-five gallons is the versatile middle of the range - weekend cruising for a crew, extended trips for a couple - and the per-order finish makes it specific to your boat: fittings spin-welded or threaded at the sizes and locations you mark. The dimensioned drawing below is where the installation starts; print it, place the fill under your deck plate, the vent at the high corner, the pickup where your hull's trim leaves the last water, and commit the layout in the fitting planner on this page.
Full, the B188 carries about 208 lb - water at 8.34 lb per gallon remains the most underestimated load aboard - so mount it flat, strapped, and low. From Tustin, California, like every tank in the line.
