In the first place, the forecast put the storm on top of Belize City, so getting the hell out of there was the thing to do. Too late to run north, (and running north earlier would have been in the face of a forecast putting the boat in the storm's forecast track) so a run south was prudent under the circumstances at the time the decision was made. Big Creek was a well known and well used santuary - and had the forecast held would have been *the* thing to do.
Hurricanes are never totally predictable - the way this one developed, its survival across the "hurricane graveyard" and its interaction with a front that came further south than forecast caused the storm's sudden dramatic strengthening and held it south, trapping the folks in Big Creek who believed they had done the most prudent thing under the circumstances.
I have reviewed the forecasts leading up to this disaster and have reached the conclusion that had I been there, I'd likely have been trapped too. And that's why I just steer clear at this time of year.
As for having passengers on board, my bet is that they arrived in Belize on the last flight in - or at least showed up on the dock after the last flight out had left - there were no hotel rooms to be had in Belize City, where an evacuation order was underway anyway, and with the forecast having the storm coming directly at Belize City the captain made the decision to embark his pax and head south for the back side of the storm.
If any of you absolutely insist on flinging blame about, then it lies on those who made the decision to continue on to Belize in the first place with a hurricane bearing down on the country. Everyone else, from the boat's captain to the weather bureau, was doing the absolute best they could with the information they had. But it wasn't good enough.
Did I mention I don't go to the Caribbean this time of year?
