Frank Denoga, 36, a fisherman from New Bedford, Massachusetts, was reported missing at sea on August 16, 2021. He was a crewmember aboard the New Bedford–based scalloping vessel Blue Wave, operating about 60 to 70 nautical miles southeast of Nantucket. The crew raised the alarm late Sunday night when Denoga failed to show for his scheduled watch and could not be found on the boat.

Denoga was reported to be wearing a sweatshirt and was not believed to have been wearing a life jacket when he went overboard. The U.S. Coast Guard launched an immediate search involving Air Station Cape Cod assets and the cutter Tybee; helicopters and surface vessels searched 1,444 square nautical miles before active searching was suspended on August 17, 2021. The Blue Wave returned to port the next morning, and remaining crew members met with Coast Guard officials as part of the investigation.

The disappearance remains unsolved. Anyone who was in the area southeast of Nantucket on August 16, 2021, or who has information about Denoga’s movements that night is asked to come forward.
