Feb 20 — Change two hemispheres at once... almost

I was originally thinking this:  A waypoint on the horizon for Jacob is 0º N, 180º W. If he does cross through that point he will go from Northern Hemisphere to Southern Hemisphere at the sametime he goes from Western Hemisphere to Eastern.  Clearly one of the unique places on earth.

Through his trip for the past eight months, his Lat has been getting smaller and his longitude has been getting bigger. Once he crosses that point, both of these will reverse. Lat will increase; he has to go from 0 at the Equator to 17 S at Cairns, and in longitude he has to go from 180 E 146 E.

But in reality he got pushed farther west, so he is now well in to eastern longitudes, but still about 1º above the equator.

After a day or so on the sea anchor, progress is back to very good. We have nice confirmation of the current models during the recent lull. Always hard to measure in the conditions he has but he is confident he was seeing 1 kt or more to the West  and that was the forecast at the time.  I think we have good current data for around Feb 14, but still have to check it.

Time to start looking out for atolls and islands. more on that later.

here is latest video update which shows the new way we are passing on forecasts to Jacob using meteograms made in LuckGrib.
