SummaryÖ Prefer the European routing but continue S until 37-38s then head
E.
1) High pressure is located 32n/87e and will remain stationary next 24-48
hours.
2) As you continue S around the western periphery your winds will back into
the NW.
3) As this happens continue S thru 6 utc Thu down to 38s to avoid lighter
wind to the E
a) Then can head E on port.
4) Meanwhile latest 6 utc GFS model run tracks a low near 38s/68e to 39s/
82e 12 utc Fri to
40s/95e by 12 utc Sat.
5) You want to ride the NW-WNW breeze north of the track of this low
eastward along 38s
after 12 utc Thu to 00 utc Sun.
6) By then this low will be to your SE and its frontal boundary will shift
thru you around 00 utc Sunday
7) When winds shift to W-WSW can go onto starboard and get south of 40in
early next week.
8) Do not see the need to go down to 46s on your GFS routing.
9) Seas will be much higher down there so prefer you stay away in the short
term as weather pattern
looks co-operative to keep you north of 40 into the weekend.
10) It will get much rougher though compared to what it has been as both
winds and seas
increase over the next few days.
RoutingÖ The 39s/87e waypoint from the European is very close to out
estimated position at 12 utc
Fri. Prefer though that you get S next 18 hours
before heading E to stay away from
lighter air to the E.
Then head E between 38-39s NE of fast moving low and
in NW-WNW wind Fri/Sat
Once the cold front overtakes you(around 00 utc
Sun) and winds shift to W-WSW then
onto starboard and can get some southing.
