ELISSA – the Hull Truth

As director of the Texas Seaport Museum and the 1877 barque ELISSA, I would like
to join with ELISSA's immediate past director, Kurt Voss, in thanking everyone
for their concern about ELISSA. Kurt and I would like to give context and
clarification to some of the rumors and reports that are floating around about
ELISSA's current state and future.

Until this year, ELISSA has conducted day sails annually for the past 29 years –
quite a remarkable accomplishment for a 133-year-old sailing ship. Being "not
seaworthy," as recently reported in the press, does not mean she is sinking or
in a neglected state – all it means is that she needs to affect some repairs to
areas of her hull plating to which the U.S. Coast Guard has called attention.
The suspect plating is less than 16% of her entire hull plating. She is indeed
facing considerable challenges, but nothing on the scale of her 1975-1982
restoration. Once before, Galveston Historical Foundation brought together the
talent and commitment necessary to get her sailing. We'll do it again. With all
the scuttlebutt that's been flying, however, we want to provide some clarification.

The ship's hull was originally built of riveted iron. About 25% of the iron was
replaced with welded steel in Greece during 1977-78. That steel—which was of the
highest quality was custom made in Houston, Texas by Armco Steel Company, to
specifications supplied by restoration director Walter Rybka. Over the years,
about another 10% to 15% of the original iron hull plates have been replaced.
Most of that replacement was made necessary by a 1984 collision, when a floating
dry-dock broke its moorings in a storm and drifted down on the ship, crumpling
the stern. Those repairs were made with riveted steel.

U.S. Coast Guard regulations require that ELISSA be dry-docked twice every five
years, which has been done religiously since 1981. During every dry-docking the
ship is thoroughly inspected by the Coast Guard, as well as the professional
staff of Galveston Historical Foundation. For the past decade, representatives
of the American Bureau of Shipping have also participated in those inspections.
Isolated corrosion has been found and remedied from time to time, occasionally
requiring partial replacement of a few of the hull plates, but no widespread
problems were ever encountered. In short, ELISSA's hull below the waterline has
always been thoroughly maintained.

When the ship was hauled this past January, the first sign of a problem was the
disappearance of an unprecedented number of the 55 sacrificial zinc anodes
scattered across the underwater surface of the hull (these are used to control
galvanic and electrolytic corrosion). Although a certain number of anodes are
replaced at every dry-docking, their rates of deterioration were never before a
surprise. After water-blasting the hull to remove marine growth, more problems
surfaced -- problems that had never been seen before. Inspectors found many
small pits (some of which penetrated entirely through the hull), as well as
numerous wasted rivets (another first). Upon further investigation by the U.S.
Coast Guard, GHF staff, representatives from the American Bureau of shipping,
and Kurt Voss (who has seen the ship out of the water at virtually every
dry-docking since 1981), all concurred that what they saw was severe
electrolytic corrosion and that it taken place since the last dry-docking in
January 2008.

After a professional marine electrical contractor verified that the shipboard
electrical system was not the source of the problem, a few temporary repairs
were made and the ship returned to her berth in Galveston. Because ELISSA is a
National Historic Landmark, the ship's management decided that a comprehensive
repair plan should be formulated, one that would utilize input from the best
experts in the field of historic ships, who, in turn, would incorporate methods
that meet the highest standards of maritime preservation. Financial realities
may dictate certain compromises, but we plan to do our best to meet those lofty
goals and retain as much historic fabric as possible while utilizing modern ship
repair methods and materials.

At present, this panel of experts is in the process of developing detailed
specifications. That is the primary reason why the ship remains temporarily
"grounded." Rather than use expedient modern repair methods, GHF's goal is to
retain as much of the original hull as possible and use traditional construction
methods on any plates that are too far gone to save. That will be a
time-consuming and expensive process, but the ELISSA deserves nothing less.

The million dollar question is: what caused such severe and unprecedented
electrolytic corrosion? The damage done definitely was not caused by neglect or
poor maintenance (the ELISSA volunteers donate over 30,000 hours a year in
maintaining ELISSA in sailing trim), and whatever the source, it happened since
January 2008. Professional experts are pursuing the answers, but all signposts
point to the destruction caused by Hurricane Ike in September 2008. Live
electricity was in the water near the ship for an undetermined length of time
(please remember that only essential personnel were allowed on the Island until
nearly two weeks after the hurricane struck). At present, the ship's shore power
system is being scrutinized for any anomalies and bi-weekly electrical potential
readings of the hull and water are being performed and logged. Regardless of
what turns out to be the culprit, professional marine electricians have
determined that the problem has been arrested and no further damage is taking
place. Logically, whatever the source, the experts agree that the electrolytic
corrosion that attacked ELISSA's hull was a direct consequence of Hurricane Ike.

Galveston Historical Foundation has launched a capital campaign to raise the
necessary funds to get ELISSA sailing again. The Foundation has employed
professional fundraisers to work with its staff and volunteers to find the $3
million necessary to make the hull sound. For further information please contact
Jamie White at . If you'd like to lend a hand
immediately, please text ELISSA to 50555 to make a $10 donation through your
cell phone. Or visit our website and make a donation to Keep ELISSA Sailing
campaign at Keep ELISSA Sailing.

Our goal is to have ELISSA sailing by the fall of 2012. Given what Galveston
Historical Foundation has accomplished with this ship in the past, you can be
confident that this goal will be met.

I was thinking of posting the same article. Thanks for doing it.
