Regarding the moment to call for help I remember that once Cammas, the one that is now skipping the French boat on the VOR, capsized his big trimaran on a transat solo race on a storm with winds that picked 70K at the middle of the Atlantic.
The French rescue services received a call at 9 AM from him telling them that he had capsized. They asked if all was alright and he says yes, the boat is upside down, but no problem with the flotation. They asked when it has happened and Cammas said at 3 AM in the morning. The Rescue guys asked him to repeat again and he repeats 3 AM. The rescue guys could not believe and ask him why he was calling only now. Cammas said that he was in no danger and that he did not wanted to spoil their rest for nothing.
This story, from a relative young sailor that is already a legend, shows what is respect for the others, absence of panic and seamanship, even on a capsized boat.
