I looked at your map. The only winds not traveling in the same easterly direction are those eddys forming close to land she wasn't sailing in those areas.
It is bizarre to provide your source as some kind of counter.
A source for her route?
You realise of course that this is a live map, not instantaneous indications of the wind at the time she was in each area. At the latitudes between 45S and Antarctica the general trend is westerly (ie blowing towards the east), but there are significant times when the wind varies considerably, from all points of the compass. Do you think that those times and "eddies" don't count? To claim that "winds on the inside of the ice ring always travel the same way" is complete fantasy.
But don't take my word; this from her blog Day 79:
"Hi All,
Last night I finally managed to get to bed by around 3am and by 4am the winds had started to veer from the SW to the W before shifting to the NW and build in strength. I needed to put a gybe in, but I decided to wait until first light to make it a little easier".
You'll know of course that a gybe is a similar manouver to a tack, but performed before the wind, so more hazardous.
She ventured a little off course in that instance, I suspect, but as I stated earlier, she was traveling with the wind.
Like I wrote, it is indeed bizarre you would provide a map that does not show an Ice Ring and only shows those eddys that are blowing to the W. She was probably caught up in one of those.
