Newly Reformulated Gasoline with Ethanol Could Rupture Old Fiberglass Gas Tanks
Explosion Hazard and Significant Engine Damage Evidenced on Large, Older Vessels
Older fiberglass fuel tanks may fail as a result of recent gasoline reformulations that are using increased concentrations of the fuel additive ethanol.
BoatU.S. believes that as a result of industry-wide changes in fiberglass resin formulations in the mid 1980's, the problem appears to be limited to tanks manufactured prior to this date. Diesel fuel systems are not affected. The fiberglass fuel tanks in question were standard equipment on some Hatteras, Bertram and possibly other boats. While the investigation is still in the preliminary stage, BoatU.S. believes that reformulations made to gasoline in the Long Island Sound area that replaced MTBE (Methyl Tertiary-Butyl Ether) in late 2004 with a 10% concentration of ethanol is causing the additive to "attack" the resin in the old fiberglass tanks. The results are weakened tank walls and bottoms with the potential to leak.
Anytime gasoline leaks into the bilge, there is a significant risk of an explosion.
BoatU.S. has confirmed reports of tank wall failure in which gasoline was found leaking into the bilge. It also has reports of a tar-like substance - possibly created from the chemical reaction between the older fiberglass resin and ethanol - causing hard black deposits that damage intake valves and pushrods, ultimately destroying the engine.
"At a minimum the problem can devalue a boat significantly since replacing damaged fuel tanks and engines can be a significant expense. However, the potential for leaking and explosion is a far greater factor," said Chuck Fort, associate editor of Seaworthy, the damage avoidance newsletter from BoatU.S.
BoatU.S. is asking boaters for any firsthand reports or other information they may have on the issue and is doing additional testing to evaluate the extent of the problem. "We'd like to know if other gasoline reformulations with lesser concentrations of ethanol react with the resin, perhaps at a slower pace," said Fort.
The increasing use of ethanol has largely been the result of federal and state efforts to replace MTBE, a potential carcinogen, with a safer alternative. MTBE and ethanol oxygenate fuel to help reduce harmful emissions when running cold engines just after startup. BoatU.S. has no reports from other states using lesser concentrations of ethanol. "Many well-regarded boat manufacturers have used fiberglass tanks reliably for years," said Fort. "But unforeseen by these builders, the new reformulation in New York and Connecticut includes a high percentage of ethanol. And unfortunately, gasoline with ethanol is the only fuel available to boaters in these areas," he added. Some stations in New Jersey may also be using ethanol-enhanced fuel.
Early symptoms may include engine backfiring and hard (sluggish) starting, in which the motor turns over slowly as though the battery were weak.
Affected engines also may not reach their rated RPM. Fort said,
"Ironically, the substance seems to pass through fuel filters leaving no tell-tale marks - some have appeared clean on our reports. The only way to know for certain is to pull the carburetor and inspect the underside for a black, gummy film which can indicate a serious problem."
Until it fully understands the extent of the issue, BoatU.S. is recommending that any early 1980's or older vessel with fiberglass gas tanks be stored empty over the winter.

Sailors World Expands to Bayfield, WI
We are pleased to announce the opening of a new sales office in downtown Bayfield, Wisconsin where we are featuring our New Island Packet Sailing Yachts 37-51’ and Packet Craft Express 40’ Power Cruiser.

“Our main office remains in Wayzata, Minnesota on Lake Minnetonka where most of the new inventory will remain,” according to Gary DeSantis owner of Sailor’s World.
Our Bayfield office will help us connect better with our current and potential customers that generally live in the areas in the cities near our main office but like some more contact and service nearer the area where they use their yacht and hopefully we can better serve them now.
The address for our Bayfield office is 24 100 Rittenhouse Avenue, Bayfield, WI 54814. We are right across the street from the Bayfield Inn. Captain Dave Skoro will be manning the office as we move towards spring.
But to reach us in the off season our main office number of 952-475-3443 is still the best one. The Bayfield number is 715-779-5203.
Heading South For The Winter? Or North For The Summer?
Low Cost Rental EPIRB Option From BOATU.S. Foundation
For thousands of boaters who summered up north and want to dodge winter's icy grip, fall is the time for the annual migration south. To save time or avoid shoaling many of these snowbirds elect to travel a portion of their trip outside the protected waters of the Intracoastal Waterway and venture into the open Atlantic Ocean. In an effort to bolster marine safety, the BoatU.S. Foundation for Boating Safety & Clean Water can provide these cruisers with a much-needed lifeline - a low cost 406MHz Emergency Position Indicating Radio Beacon (EPIRB).
This rental program makes these $800 life-saving devices available as low as $50 per week as a public service. Reservations can be made online up to six months in advance at http://www.BoatUS.com/foundation/epirb or by calling 888-663-7472. The rental fee includes round trip shipping via three-day service and the BoatU.S. Foundation handles all of the critical registration information.
"By going online we can have an EPIRB delivered to your door in a matter of days," said David Carter, manager of the BoatU.S. EPIRB Rental Program.
Carter also cautioned against borrowing an EPIRB from another vessel as it could hamper rescue efforts. "The EPIRB registration information is married to the vessel. You don't want the authorities looking for the wrong boat," he said.
The BoatU.S Foundation for Boating Safety and Clean Water is a national
501(c)(3) nonprofit education and research organization.
