The Maine Marine Patrol has located the sunken fishing boat of a missing father and son, using a remotely operated underwater vehicle to identify the wreck in about 160 feet of water in Moose Cove in Washington County.

The marine patrol also found what it believes is a body onboard the 34-foot “Sudden Impact.” Neither the boat nor the body has been recovered.

Chester “Chet” Barrett and his son Aaron, commercial scallop fishermen from South Addison, were reported missing Saturday by a family member when they didn’t return from a trip that began at Cobscook Bay State Park in Edmunds around 5 a.m.

A GoFundMe page supporting Melanie Barrett, Chet’s wife and Aaron’s mother, describes them as adventurous men who loved the water, lobster fishing in South Addison and scallop dragging in Cobscook Bay. The father and son had contagious laughs and always had a story to share around the fire pit at their camp at Schoodic Lake, according to the donation page.

The coastal area where they went missing between the towns of Cutler and Lubec in Washington County has “strong tidal current activity,” the marine patrol said. The agency relied on the expertise of four local fishermen to navigate the strong currents and assist in the search, Capt. Mark MacDonald said in a phone interview Thursday night.

The search for the missing men and “Sudden Impact” began Saturday evening but was briefly suspended by the U.S. Coast Guard after sunset the following day. The Maine Marine Patrol had temporarily suspended the search twice due to poor visibility.

On Sunday, local fishermen using sonar found an object in 160 feet of water about one mile offshore in Moose Cove. The Coast Guard stopped its attempt to recover the suspected wreck because of safety concerns, and the marine patrol said it would continue on Tuesday.

Marine patrol officers took advantage of a short window when the tide ebbed around 11 p.m. Wednesday to conduct their search near the cove, the Maine Department of Marine Resources said.

Rescue boats anchored to the sunken ship, MacDonald said, and had about 15 minutes before the tide picked up to send a remotely operated underwater vehicle toward the object. He said the ROV, equipped with sonar, LED lights and a camera, helped the marine patrol confirm the boat was the “Sudden Impact.”

Then, MacDonald said, a family member on the surface helped them maneuver the ROV inside the vessel, where it found what appeared to be a body. MacDonald said he couldn’t say for sure who it was because it was so dark.

The search ended when the tide began to turn.

“It’s hard to stand by knowing he’s down there,” MacDonald said.

He said the men were experienced, competent fishermen. Though the weather that day was poor, it’s hard to know what went wrong. Commercial fishermen often put their lives on the line, MacDonald said.

The Maine Marine Patrol is working with the family to decide what to do next, and will consult with deep-water salvage experts to see if recovery is possible. MacDonald said the family is looking to hire a specialized diver who has the ability to work in difficult conditions.
