Details are still not clear on this, but a woman survived a boat capsize then (possibly) swam/drifted for 6 hours in very cold water then walked overland for a few more hours before she found help. Other then severe hypothermia, she is very lucky to be alive.

I am suprised that they did not have a marine radio to try and call for help as in that area, there are usually steady boater traffic. A PLB would of probably made a big difference also.

A few more details here.
