Day 11 Mexico to the Marquesas

April 14, 2012
9PM boat time
Position at 0400 April 14, 2012 UTC: 06°47'N 122°22'W

Day 11: Mexico to Marquesas Islands, French Polynesia

All is well aboard.
Starting to meet some squally weather and spent the day under 100% cloud cover. The cloud cover was a welcome change to the burning sun. Some people say you get just as sun burned on a cloudy day, we disagree. Despite sitting on deck all day no one got the least bit red.

In regards to weather, it seems we are going to be a whole lot less lucky crossing the ITCZ compared to last time (2006) when we missed all the convection, squalls, heavy rain and fluky winds.

Based on a recent weather discussion product we downloaded through Sailmail.

We found this snippet about the ITCZ

ITCZ AXIS EXTENDS FROM 02N101W TO 04N107W TO 04N132W TO 02N140W.
SCATTERED MODERATE CONVECTION WITHIN 90 NM OF AXIS BETWEEN 111W
AND 132W.


We also downloaded a grib file from query@saildocs.com by sending a email with this is the message body:
send GFS:07N,02N,126W,121W|-0.5,0.5|3,6..72|PRMSL,WIND,RAIN

Within a few minutes you get a reply with a nice little grib file (you need a GRIB viewer to check it out, but here are free on the downloading on the internet) showing major amounts of precipitation and then a whole lot of ocean with very little wind. The good news is we have full fuel tanks so when we get to the nasty area we can turn south and motor through the ITCZ.

That's all for now,

At this moment 24 knots of true wind out of the NE with light rain.
