Ericsson arrival at Cape Horn delayed by six hours - latest projection

by Richard Gladwell, Sail-World.com on 17 Mar 2009
The leaders in the Volvo Ocean Race are not now expected to round Cape Horn until 1000hrs on 17 March (GMT or 2300hrs NZT tonight 17 March

The time is about six hours slower than projected yesterday and and is caused by the race leaders Ericsson 3 and 4 sailing in a lighter patch (20kts) of air around 250nm from the Cape at 0700NZT on 17 March or 1800hrs on 16 March GMT.

From there, race leader Ericsson 3 rides on a stronger breeze, but probably not as strong as that which will be experienced by the the two following boats Puma racing which is almost 200nm astern and Green Dragon which is another 100nm astern.

How to read these images

The boats have four digit codes as follows: ERT3 - Ericsson 3; ERT4 - Ericsson 4; GDRA - Green Dragon; ILMO - PUMA Racing; TELA - Telefonica Blue;

The wind is shown in barbed arrow format. The longer line is the wind direction, if it has one longer barb at right angles to the tail, then the wind strength is 10 kts, if there is a half size barb, further up the shaft then the strength is 15kts, two full size barbs indicate 20kts and so on.
