Jun 1—Great progress; ETA in hand

Background: Notes here on our Google Earth tracking of Jacob Adoram

We are updating frequently now, so best to download the KML file and update your Google Earth.

Jacob is making good about 2.3 kts, on course to Flora Pass, which at 18z on Sat Jun 1 is just 62 nmi off.  He is getting some help from the currents, and wind is strong and right on the stern.  We see this in the ASCAT images, but strangely the WindSAT data do not agree.  This we will look into elsewhere. (We also have to consider that Jacob has indeed seen periods of wind at 10 kts from 070, so maybe there is some chance the WindSat captured this unusual transient wind.)

We note that the local coastal forecast from Cairns is still 20 to 25 kts, but we have at least one example where this was an overestimate. For Jacob and his boat, 20 kts is difficult to steer in, but 25 kts is notably more difficult, with much limited range of headings.

Below is a video discussion of these points and others...
