The Saint Helena High comes back for more

Weather forecast for November 28th at 8h00

© Great CircleWhile the first 10 boats are sailing at high speeds in the roaring forties with 18 to 25 knot NW'ly winds, things are getting more complicated for the protagonists who have to deal with a significant Saint Helena High. We see on the first image that this high pressure zone is inflating in the West.

The second image shows that on Monday this light wind zone (in blue) is moving south of the group, which is still navigating its way through SE'ly trade winds. True to form, the Saint Helena High, is going to block the route towards the Deep South. 

3 competitors have apparently chosen to bypass the anticyclone via the West (Roura, 0'Coineen and Heerema). They are sailing downwind and should not stall too much. The rest of the fleet clearly preferred a shorter route. They're sailing upwind in an easing breeze, which is getting lighter with a big swell. The conditions are not easy © Great Circleand it's unlikely to improve tomorrow with the wind getting even lighter.

Which is the best choice? A longer route with favorable winds or a more direct route with lighter headwinds? Answer within 48 or 72 hours, once the whole fleet hits the Roaring Forties.
