Estimated position on Saturday 27. nov 2010

I'm trying an updated estimate of the position for Bent and his crew on Zephyr today on Saturday, after 4 days at sea.  I've noticed that my GRIB-files (from the weather meteorologists) told that the wind died on them on Thursday then changing to a weak wind straight ahead.  If they have been using an average speed on 4 knots night and day since start from Poerto Rico - they should now be half way to Cape Verde.
I'll estimate current position at end of the white line
The low pressure (marked with "o o" on the map) will move during this Saturday NE and cross Zephyr today so our friends will suddenly loose the westward wind which will change to east during Saturday evening.
As shown in the Meteogram below, they're having 23 degree Celsius, no rain but mostly clouded and little wind - you can see the windshift at 18:00
