SummaryÖ
1) Like your position very much ñ thank you and good work!
2) Low pressure south of Madagascar is moving away, so the threat of a big
header is ending
3) There is a suspicious area of thunderstorms near 10-12S/75-80E
a) I do think a low will form in this area, but should move slowly S or
SE from there
b) this system is not a problem for you guys
4) Easterlies will start to veer later tonight/Sun morning
a) would like to cross 60E on or before 21S, but goal now is to maximize
boat speed towards the N and NNE
5) Doldrums still look like a mess and will aim to cross 10S around 61-63E
a) looks better to the E than to the W, but donít want to waste our good
wind speeds over the next 36 hrs trying to go further E
b) bottom-line, if winds are further right/sailing angles allow you to
point further E, without hurting boat speed then do it
c) doldrums look more complicated/wider to the W of 60E
6) Todayís weather model forms another low pressure between 5-10S/W of 65E
a) GFS has a habit of this and over forecast the number of lows by at
least 60-75%
b) should not base any strategy on any equatorial low until we see some
squall/thunderstorm activity, which is signal for low pressure development
7) Strategy still the same
a) try to go N as best you can when you hit the light winds
b) port tack when in W and NW winds ñ goal is again, as fast as possible
towards the N
c) hold port tack until the winds veer into the NE and then go to
starboard ñ goal is to get max distance N
Wind directions are TRUE, wind speed in kts, and time is UTC
