Since Deadliest Catch premiered on the Discovery Channel in 2005, perhaps only one of the featured ships can be said to have 'crashed' during that time, though several have sunk.
A Ship Featured in the Show Which Sank
The most notable loss came in the very first season of Deadliest Catch, when Big Valley, another 92 foot long vessel, capsized and sank 70 miles west of St Paul Island. Of the crew of 6, only one man survived. The Coast Guard Investigation into the incident concluded the ship had capsized due to excessive weight, with Big Valley taking to sea with three times the permitted cargo of bait.
