Off of the main topic but I highly recommend reading two articles titled "Bigger Than The Weather". I can only find part II. https://www.dailymaverick.co.za/art...eather-ii-the-corporate-cover-up-goes-deeper/ Try and find part 1 if that sort of thing interests you.
Interesting read - regardless of who that epirb was registered to,(unless it was the old non gps type) if it had of gone off it would have raised alarm bells as in registered contact getting a phone call within an hour of it going off.
So either it was the old type & wasn't picked up or if the gps type then it never got activated or self activated.
2015 - i'd be surprised if even yachts would be allowed to use the old type but perhaps possible.
