Obviously we don't know the facts yet and whatever happened it is a terrible tragedy...
The thing is if you are not familiar with the area the sea at Calis tends to get really rough, we were looking out for dolphins a while back and Derek said to me god he/she is a bit far out I had a look and it was someone on a lilo that did really look a long way away, I said do you think we should tell someone (who I don't know)but after watching for a bit longer we realised the way the current was the person was getting brought back in instead of taken out to sea...
