Matt... You did everything possible to give her a chance so, whatever the outcome, well done.

Phoning VISAR (Office 284 494 4357) will be your best chance of finding out what happened. Alternatively I suggest calling TMM charters. Sam Welch at TMM is one of the Rescue Coordinators and Mark Sanders is/was one of the Helms. They or probably anyone in the TMM office (284-494-2751) will know.
