D/V Tenacious Team Discovers Wreckage of ST Seiner

Atlantic Wreck Salvage (AWS), owner and operator of D/V Tenacious, today announced the discovery of the wreckage of the steam trawler Seiner, a WWI-era fishing vessel that disappeared in the fishing grounds of Georges Bank in January of 1929.  

ST Seiner was a 139-foot, steel-built steam trawler with a double-drum trawl winch and a raised forecastle deck built by Rice Brothers Corporation of Boothbay, Maine in 1921. The ship departed from New London, CT on January 9, 1929, and was last heard from on the 18th when her captain, Thomas Miller, made a required daily report to the vessel’s owner, Portland Trawling Company. Concerns grew when Seiner failed to make her January 19 report and again when she missed her scheduled return to port on January 22. It is believed that the vessel foundered in a storm. Her entire crew of 21 men went down with the ship. 

A team from D/V Tenacious, led by Captains Joe Mazraani and Eric Takakjian, discovered the wreck site in 2022 using side scan sonar. Time and weather constraints prevented the team from diving the wreckage at the time. They returned to the site on July 27 and 28, 2025, and made a total of seven dives. “The team was able to identify Seiner from features such as the double drum trawl winch, remains of the raised forecastle deck, shape of the stern, and the presence of a steam engine and boiler,” said Captain Takakjian, who has participated in the discovery of almost 100 shipwrecks. “No other steel or iron hull steam trawlers of this size are known to have sunk on Georges Bank.”  

Takakjian first became aware of the Seiner sinking in the 1990s when he was researching trawlers sunk by German U-boats during WWI. Although Seiner sank during a storm shortly after the war, it came up in searches for other vessels and set him on a path towards finding her. Seiner’s location so far from shore and in the deep, high-current waters that run through Georges Bank made locating and diving the wreck too great of a technical challenge in the 1990s.  

D/V Tenacious located the wreckage in 2022 as part of expedition to Georges Bank. They returned to the area on July 27, 2025, re-scanned the target, and confirmed that the vessel’s length and beam match that of Seiner. Seiner rests approximately 125 miles from Nantucket, on the eastern edge of Georges Bank, in approximately 200 feet of water. 

When the ship went missing in 1929, Portland Trawling Company and the US Coast Guard mounted a search and rescue mission that involved private fishing vessels, twelve patrol boats, and two destroyers. They found no survivors. 

“The discovery of a new shipwreck can be bittersweet. While the team celebrates this important historical find, we are mindful of the loss endured by the families, colleagues, and loved one of those who went down with the ship,” said Jennifer Sellitti of Atlantic Wreck Salvage and D/V Tenacious. “We hope this discovery can provide some measure of closure to the descendants of those who perished.”
