Several members of the crew are from Maine, including a man from Wilton.

Aircraft and ships taking part in the search located a container that appears to have come from the 790-foot El Faro, according to the owner of the vessel, while the Coast Guard said it has found a debris field that includes what appear to be pieces of container. They also spotted an oil sheen in the sea.

The latest finds follow the discovery of an orange ring that was confirmed to have come from the El Faro a day earlier. Chief Petty Officer Bobby Nash said it was too early to come to any conclusion.

“We still don’t have communication with the ship and we don’t even know if the debris field is from the ship,” said Nash, a Coast Guard spokesman.

The fourth-day of searching across a wide expanse of the Atlantic Ocean near Crooked Island was aided by the first day of calmer weather now that Joaquin has left the Bahamas and was en route to Bermuda. Two Coast Guard cutters, the Northland and Resolute, were expected to continue searching overnight Sunday as the aircraft returned to their bases.

Authorities lost contact with the El Faro early Thursday as the ship sailed through the Bahamas at the height of the storm as it sailed from its homeport in Jacksonville, Fla., to San Juan, Puerto Rico.

Ronald Holland is the father of crew member Michael Holland of Jay. He told The Associated Press he hadn’t heard much about the search for the vessel and was leaving soon for Florida.

Holland’s mother, Deb Roberts, told WCSH-TV that waiting and wondering had been difficult, but she remained very hopeful she will be reunited with her son.

Family members of the crew said they were trying to remain optimistic, but were also clearly in agony as they anxiously awaited word of any developments at the Seafarer’s International Union hall in Jacksonville. Some sobbed and hugged each other.

“This is torture,” Mary Shevory, mother of crew member Mariette Wright.

Shevory, who had come to the Seafarer’s Union Hall in Jacksonville from her home in Massachusetts, said her 51-year-old daughter was devoted to her job working on the ship.

“I’m just praying to God they find the ship and bring my daughter and everyone on it home,” she said.

Laurie Bobillot, whose daughter, Danielle Randolph, is a second mate on the El Faro, said Sunday she was trying not to lose hope after nearly four days anxiously waiting for news of the ship from its owner, TOTE Maritime Puerto Rico.

“We’ve got to stay positive,” said Bobillot, of Rockland, Maine. “These kids are trained. Every week they have abandon ship drills.”

The El Faro departed from Jacksonville on Sept. 29, when Joaquin was still a tropical storm, with 28 crew members from the United States and five from Poland. The ship was heading to Puerto Rico on a regular cargo supply run to the U.S. island territory when it ran into trouble. It was being battered by winds of more than 130 mph and waves of up to 30 feet.

The crew reported that the ship had lost power, had taken on water and was listing 15 degrees but that the situation was “manageable,” in their last communication on Thursday morning, TOTE Maritime Puerto Rico, said. They have not been heard from since.

The first sign of the ship, an orange life ring, was found Saturday about 120 miles northeast of Crooked Island. That was followed by floating debris and the oil sheen on Sunday.

TOTE Maritime Puerto Rico said a contracted tugboat and another of its ships had found a container that appears to be from the El Faro. But “there has been no sighting of the El Faro or any life boats,” company president Tim Nolan said in a statement.

The company has defended its decision to authorize voyage. Crew members were “equipped to handle situations such as changing weather,” it said in a statement.

Bobillot and Robin Roberts, whose stepson Mike Holland is an engineer on the El Faro, said they had faith in the skill of the ship’s captain, whose name the company has declined to release.

“This is a top-notch captain. He’s well-educated,” Bobillot said. “He would not have put the life of his crew in danger, and would not have out his own life in danger, had he known there was danger out there. He had the best intentions. He has a family, too, and he wanted to go home to them, too. That storm just came up way too fast.”
