This Washington Post article by Ian Shapira is the most comprehensive account I've seen of what happened to HMS Bounty, a replica of the 18th century tall ship which starred in the 1962 Marlon Brando "Mutiny on the Bounty" film, and various Pirates of the Caribbean movies. No definitive word on exactly what caused the accident, but many theories.
In the LA Times today, a remembrance of Ms. Christian.
Even other sea captains are mystified.
