It's starting to sound like the captain did everything wrong:
Steered to close to the island without permission.
Refused to abandon ship.
Refused to stay with with ship to oversee the evacuation.
Refused to go back to the ship when the coastguard ordered him to.
I always thought that you had to have served as a naval officer before they let you take charge of a thousand foot, quarter of million tonne, half a billion dollar pleasure dinghy.
