Event: sail around the world
Last Position: 41 52s/12 46e at 1230utc Fri Feb 27
Prepared: 1300utc Friday, February 27, 2009
SummaryÖ
1) I agree Charles ñ we should try to route S of the high pressure cell
a) big issue is getting back to the N at an appropriate time, which I
think we can do between 55-65E
2) High pressure cell at 1200UTC Fri is near 38-39S/5W and will move ESE
a) looks to stay along or N of 43S, as it moves E between 30-50E
b) I take you to 44S and this avoids much of the Aghulas current features
3) SW winds will remain fresh thru Sat
a) I have you aiming for 42 30-43S/18E and then 44S/28-30E. We can go a
bit further S, but I hesitate to go S of 45S since we do have to get back to
the NE by 60-65E
4) By 1200UTC Sun, the high will be very close to you at 42-43S/30-35E
a) cold front will be near 50S/11E to 40S/2-3E
b) your SW winds on Sat will diminish and veer into Sun ñ we hold
starboard until the winds become 260 and then we go to port
c) would like to hit 40S around 55-60E, but going too far N too soon will
give you NE winds while the favorable NW winds will be found closer to 45S
d) bottom-line, fast starboard, staying N of 45S, until the winds
diminish and veer and then optimum angle for 40S/55-60E
5) We should fall behind the high pressure cell Sun night/Mon with the winds
becoming N and NNE
a) winds further right to the N and winds further left to the S, but
really want to hit 40S by 55-60E ñ okay to miss a bit further E than W
6) Cold front will be slow to approach, as the high pressure cell slows and
builds E of 60E
a) N and NNE winds slowly increase Mon ñ Tue
7) Will not be a smooth transition Wed ñ Fri into the trade winds as the
cold front will be slow
to move NE
a) trade winds look great N of 35S/between 60-70E, but may be sticky
getting there
RoutingÖ
1) Starboard gybe as fast as practical, aiming for 42 30-43S/18E and then
44S/28-30E
a) okay to be a bit further S
2) Once the high passes and winds become light N and NNE, aim for 40S/55-60E
a) okay to be a bit further E, if necessary
