From the Skipper at 0:25:
Searching for stream, should be close. going 7+. Lots of storm clouds and warm water
And later at 05:43:
Found stream. added 3 knots of speed. Punishing t-storms pushed us out to the east. Going 8+. Pounding off waves. Haven't been able to sleep yet. Hope things settle down soon. Moving quickly the right way and happy to see dawn.
Other boats in their class went way west to catch the stream, with good results. For now Freedom has lost her lead on the race course, but with over 300 miles to go a lot can happen.
