1:20 PM PT -- Despite initial local reports, we're told the Mary B II boat involved in this tragedy was never featured on 'Dungeon Cove,' nor were the crew members who died.
However, this dangerous stretch of sea is the subject of the 'Deadliest Catch' spin-off series.
A rep for Discovery tells us ... "We are deeply saddened by the news as we feel part of the crabbing community. Our thoughts and prayers go out to their families and the entire community during this difficult time."
A sea vessel featured on "Deadliest Catch: Dungeon Cove" capsized in treacherous waters, tragically killing 3 fishermen ... according to reports.
The U.S. Coast Guard was escorting the Mary B II commercial crab boat Tuesday night around 10 PM off the coast of Newport, Oregon. The boat capsized during the escort in 12 to 14-foot seas while crossing Yaquina Bay bar and there was an immediate rescue effort.
Sadly, the Coast Guard was unable to save the 3 crew members onboard. KGW8 reports the bodies of 2 of the 3 fishermen were recovered, but the third is still trapped inside the sunken boat.
The Mary B II was featured on the Discovery show, and the premise of 'Dungeon Cove' revolves around the danger of crossing the Newport bar with a full load of crab ... which is apparently what led to this accident.
