U.S. Coast Guard and Navy aircraft combed the Atlantic Ocean around the lightly populated Crooked Island for the El Faro, which was en route from Jacksonville, Fla., to San Juan, Puerto Rico, at the height of the powerful storm. In its last communication, the crew reported that the vessel had lost propulsion and had taken on water but it was being pumped successfully, TOTE Maritime Puerto Rico, the operator of the El Faro, said in a statement. Coast Guard officials said the search, across about 850 square nautical miles of ocean, had to be called off Friday because of darkness. The search area is vast and the effort is hampered by the fact that there are few vessels out there because of the rough weather, said Chris Lloyd, the operations manager of the Bahamas Air Sea and Rescue Association, which was not helping look for the ship because the area is beyond its reach.
