The body of a 41-year-old Wilmington man who fell off a harbor cruise boat Saturday was found in Boston Harbor Tuesday, authorities said.
The body was recovered at about 1:15 p.m. between Spectacle Island and Castle Island, the Suffolk district attorney’s office said in a statement.
Boston and Quincy police used sonar in the recovery. The body was taken to the Boston Police Department’s Marine Unit, where State Police are leading the death investigation, the statement said.
The identity of the man is not being released because the death does not immediately appear to be suspicious, the district attorney’s office said.
An autopsy will determine the cause of death, according to the district attorney’s office.
The man had been on a country-music-themed cruise aboard the Provincetown II when he engaged in horseplay, according to the Bay State Cruise company, which operated the boat. The man was with his girlfriend and began to climb a railing when he fell into the water at about 10:45 p.m., Bay State Cruise said.
Crew members were unable to find the man, as his body did not resurface after the fall. The search for him was called off late Sunday afternoon after more than 17 hours.
Police assigned to the Suffolk district attorney’s office are also investigating the case.
