FV Trident

Themes

Marchioness Bowbell

Themes

Issues

FV Gaul

Themes

Water

The FV Gaul Inquiry (2004) was a high-profile re-opening of a 30-year-old mystery. It sought to provide a definitive answer to the disappearance of the Hull-based trawler Gaul, which vanished in the Barents Sea during the Cold War, spawning decades of conspiracy theories regarding Soviet espionage.

Issues

MV Derbyshire

Themes

Water

The re-opened inquiry definitively exonerated the crew, concluding that the ship sank due to a "chain reaction" of flooding in the bow caused by broken air vents, which led to the catastrophic collapse of the main hatch covers under the weight of the sea.
