Also, remember that FRP tanks are not necessarily light in weight or inexpensive. Keep in mind, however, that properly made, tested, and maintained fuel tanks are probably a boat’s most important safety feature.

Gray claims that ordinary polyester resin will usually withstand the 25-minute fire exposure, and a coat of fire-resistant paint on the outside is optional if you need more peace of mind.įire retardant resinsare more expensive, not always easy to find, and more difficult to use, but are acceptable and may be required on large, commercial passenger-carrying craft.įor those not experienced in making FRP tanks and who want to know more about it, the following may prove of interest. Your insurance company may require that your boat’s tanks adhere to these recommendations or be otherwise “certified.”īasically, ABYC standards require that tanks be liquid- and vapor-tight, and withstand the effects of fuel, lube oil, bilge solvents, salt or fresh water, fire, or other hazards Tanks must show, in a certain manner, the maker’s name and address, date made, tank capacity, material specification and thickness, fuel type to be used, maximum test pressure, and other incidental wording one would probably have abandoned ship by then.īy implication it may seem that fire-retardant resins should be used for tanks, but this is often overemphasized and not an ABYC requirement, although at one time it was a requirement under the old BIA standards. These tank makers are no doubt familiar with the construction, installation, and testing recommendations (including pressure-impulse strength tests) published in the American Boat & Yacht Council’s (ABYC) Standards and Recommended Practices for Small Craft”, specifically Sections H-24 (Gasoline Fuel Systems), and H-33 (Diesel Fuel Systems).
