Event: sail around the world
Last Position: 37 33s/80 23e at 1215utc Thu, Jan 22
Prepared: 1315utc Thursday, January 22, 2009
SummaryÖ
1) Remember, the E side of the cold front is the best location, so we want
to work that side of
the front as much as possible
a) E side of the cold front will see a more stable, consistent wind
b) temps will be less cold and the sea state will be less harsh, so
c) I very interested in staying on port gybe, sailing deep, and fast
d) primary concern will be the location the high pressure to the N ñ
don’t want to get into the light wind field near the high and
e) don’t want to get hung up with a stalled/stalling cold front and the
lighter, unstable, winds near the frontal zone
2) At 1200UTC today, the high pressure area is located near 31-32S/86-90E
a) this high pressure cell will start to elongate ESE after 00UTC Sat ñ
being on port gybe and with our winds backing, we will need to keep a close
eye on this high pressure cell Sun. If we get too close, a 6 hr period on
starboard gybe will work just fine
3) Must watch out for the frontal zone
a) cold front is near 39-40S/70-72E at 1200UTC today
b) this cold front will stall in a WNW to ESE direction near
38-40S/95-105E on Sat, so must stay N of this location, as winds will be
fickle in this frontal zone
4) Good NW winds for another 12 hrs, so port gybe, deep and fast
a) NW winds will ease and back after 00UTC Fri, but want to stay on port
gybe, since I do not want to run into or cross the stalling frontal zone
this weekend
b) much lighter W and WNW winds later Sat/Sun ñ don’t want to go N of 35S
and do not want to see wind speeds below 15 kts, so will have to go onto
starboard at some point in time ñ I do this for 6 hrs at 1200UTC Sun, but
could occur earlier than that
5) Stronger cold front will arrive early next week
a) stronger NW winds will arrive ahead of this cold front on Mon, so back
to port gybe, deep and fast to the E or ESE
b) cold front will pass Mon night/early Tue and then onto starboard ñ we
will use this period to get SE, so we can clear Tasmania
Routing
1) As fast as possible on port gybe
2) Once winds back and diminish, hold port gybe, but do not go N of 35S and
try to stay N of 38S
3) Will be back to port ahead of the cold front late Mon/Tue
a) will get SE, after the cold front passes late Mon/Tue
Wind directions are TRUE, wind speed in kts, and time is UTC
