On YouTube a channel called slow boat sailing has there conference call to media on it,seems they were lucky to survive the attacking 40 to 50 ft tiger sharks etc which went on to destroy someone else's boat because they saw the wreckage a few days later.
I watched that yesterday too.
Apparently the tiger sharks were teaching their young how to hunt by attacking their 50ft sailboat. They managed to survive by huddling on the floor really quietly because the sharks could hear them breathing.
It is also pretty amazing that they entered the "Devil's Triangle" an area where "if boats go in they rarely come out and if they do their is no one on them" because apparently it is a "tiger shark location" and still survived!!
I can't wait to see the movie, it's going to be a cracker!
