The famed anticyclone is renowned for dominating the South Atlantic and making tricky sailing for Volvo Ocean Race teams heading north or south.
Constantly expanding and contracting, the St Helena High – also known as the South Atlantic High Pressure Cell – is currently centred around 1,300 miles east of the Leg 8 start city Itajai.
However its influence stretches 1,000 miles in every direction, causing a major navigational problem for the seven Volvo Ocean Race teams.
Charles Caudrelier’s Dongfeng had the upper hand – albeit a very small one – as the 1300 UTC position report was released showing the Franco-Chinese outfit with a two-mile jump on second-placed MAPFRE.
Around 16 miles separates Dongfeng in the east from Sun Hung Kai/Scallywag, the most westerly boat, while Team Brunel were the most southerly boat some five miles below the leaders.
Dongfeng’s Daryl Wislang says “It’s the classic upwind slog – and we’ve probably got this for six days.
“We’ve done a pretty good job at the moment actually, everyone else is behind us. I don’t mind it being upwind so long as everyone else is behind us. It’s a pleasant change – it reminds us that what we’ve just endured [in the Southern Ocean] is pretty special.”
The long-term strategy remains to get east as fast as possible, in search of stronger, more favourable breeze and less current deeper in the South Atlantic.
In order to do that, the teams have had plenty of tacks and sail changes with more in store as they zigzag their way around the St Helena High’s north-western edge.
It’s made for a testing first two days to Leg 8, which will see them race 5,700 miles north to the American yachting mecca of Newport, Rhode Island.
Scallywag crewman Pete Cumming, a new addition to the team for Leg 8, says “We’ve had quite a lot of cloud activity. They’re sucking and blowing, and when you’re on the edge of the clouds the wind does very different things.
“It’s really up and down, and swinging all over the place. You have to just position yourself how you think you’ll get the best out of them.”
Onboard team AkzoNobel, the ever-changing wind speed and direction has been causing havoc with their sail selection. AkzoNobel’s Luke Molloy says “The difficulty is we’re right on the crossover of our sails between the masthead code zero and the J1 jib,”
“We were sailing in and out of the crossover all yesterday afternoon and into the evening. The problem is that if you take the time to do the sail change you need to then consider how much distance you lose versus how much you gain with the new sail.”
With less than 500 miles sailed, the race to Newport is only just warming up.
The race tracker will remain live until 1900 UTC today when it will revert to regular race-time position updates.
