Over the last 48 hours, Thomas Coville and his Sodebo have made the best progress against the solo non-stop round the world record holder Francis Joyon since leaving the north Atlantic, their deficit now down to 1,000 miles. As reported Coville's objective on leaving the Southern Ocean is to be no more than 1,000 miles behind Joyon's record pace as he believes Sodebo can make up the ground on the return journey back up the Atlantic.

Coville's progress comes despite the French skipper having to route himself around a giant area of icebergs some 2000km long and spanning 51-62°S in latitude (see below). This explains Sodebo's dramatic turn north over the last 24 hours, back up from 58°S to 54 and as the chart below shows she will have to return up to 50°S by the time she reaches around 127°W. This will add considerable miles to her route to Cape Horn. Information about the proximity of ice has been provided by CLS Argos and enables ice zones to be established with reasonable precision, although the satellite technology used can only locate icebergs down 100m in size. 

50°S 127°W is 850 miles away from Sodebo at the latest sched. At present she has a large area of high pressure to her northwest and she is sailing in southwesterly winds, but to avoid light winds at 0545 GMT this morning Coville put in a hitch to the southeast. It is likely he will gybe back later this morning.

The southwesterlies look set to get Sodebo up to this 'waypoint' by tomorrow afternoon. At this point she will be able to heat up as she turns east and then southeast. Conditions still seem to be favourable over this period but the added mileage will certainly not help Sodebo's position relative to IDEC and the hard miles earned over the last 48 hours could well be lost again.
