SAN ANTONIO -

The operators of a cruise vessel stranded in the Gulf of Mexico after a weekend engine fire say the ship has drifted so far north of its original position that they will tow the ship to Mobile, Ala., instead of their original plan for Progreso, Mexico.

Carnival Cruise Lines President and CEO Gerry Cahill says in a statement Monday evening that strong currents lead the vessel, the Carnival Triumph, to drift about 90 miles north of its original position off the Yucatan Peninsula, where it was located when the fire erupted Sunday in the engine room. No one was injured and the fire was extinguished.

Cahill's statement says the ship should arrive in Mobile on Thursday and that it will allow for less complicated re-entry for passengers without passports.

KSAT spoke to a San Antonio woman who says her boyfriend is aboard the ship celebrating his bachelor party with friends.

Amy Weber said her boyfriend described rough conditions to her that include no running water, no working toilets and no power.

"There were like toilets overflowing, and there is sewage and apparently, they are not staying in their staterooms," said Weber.

Weber says the passengers are being served fruit and salad to eat. She has also heard that fights have even broken out.
