Alex Thomson has clawed back some distance on the Vendee race leader and is now 136 nm behind Armel Le Cléac’h.
The duo are still making only moderate speeds beating upwind in contrary, N'ly winds.
They are making east as they seek to connect with the E'ly trade winds which are still a further 300 miles or around 24 hours to their north.
The British and French skippers should reach the more favourable breezes at around the same time, tacking on to starboard for the long climb north towards the Doldrums.
Because Thomson is further to the east his payback should come when he reaches the trades at around the same time as his French rival.
The tension is set to continue into the North Atlantic, assuming both have a similar Doldrums crossing.
Everything is going well for the four other boats in the South Atlantic.
Jérémie Beyou (Maître CoQ) is firmly in third place, gaining over 100 miles on Alex Thomson, although the British sailor is still 513 miles ahead.
Jean-Pierre Dick on StMichel-Virbac is fourth.
He has picked up speed again 400 miles NE of the Falklands and 150 miles north of the inseparable pair, Yann Eliès and Jean Le Cam.
