For de med interesse for været vi får. Om dere ser på kartet så ser dere da også hvor vi er i forhold til været. Dere ser også i meldingen hvor Commandersweather forventer at vi er. Vi ligger litt bak skjemaet.
 
En ting jeg har glemt å nevne i forhold til vind og fart:
 
Vi holder en lavere snittfart enn hva vi forventet. Dette grunnes egentlig ikke vinden, men bølgene. Selv om vi til tider har lite vind så har vi i løpet av et døgn vind nok til å kunne gå uten motor og ha en ok fremdrift. Bølgene er såpass store (selv om det er nesten vindstille) at de stopper mye av fremdriften. Har vi 10-12 knop vind greier vi ikke mer enn 3 knop fremdrift pga bølgene. Retningen på vinden har her også betydning og vi sliter en del med at vi ikke greier å holde vinkelen skarp nok mot Azorene.
 
Når det er sagt så har vi også hatt over 10 knop bare på cutterseilet Winking smile emoticon
 
Her er værmedlingen:
 
To: Morten Persson and crew of “ Coral IV”
From: Commanders Weather Corp, tel 603-882-6789
Route: St Lucia to Azores to England
Last Position:  27 33N/42 46W at 1700UTC Sat, March 16
Prepared: 1100UTC Monday, March 18, 2013

Summary…
1) Light conditions for the next 12-18 hrs or so, but will be increasing
later tonight into Tue and becoming quite rough Wed into Thu, as low
pressure tracks E, north of Azores
  a) could see gusts to 40-50 kts late Wed
2) Forecast below shows, if you continue with a 6 kts pace toward Azores,
but if you slow down, this will help conditions
3) Right now, there is a ridge of high pressure near 28N, extending W to S
of Bermuda, while cold front resides well to NE and stretches SW to Bermuda
  a) you are just N or NE of this ridge in a light W to W-NW breeze
4) Think you will see a W-NW to W breeze, increasing some into tonight,
then shifts more left into W-SW or SW overnight into Tue, as cold front
pushes SE
  a) wind into teens to low 20s during Tue, and
  b) there is chance for showers and squalls at night, as cold front
approaches from NW
5) Cold front pushes thru by early Wed AM
6) Behind this front, there will be a W-NW breeze for a time into Wed AM,
but
7) As low pressure strengthens and moves more SE, there will be an
increasing W-SW flow later Wed into Wed evening
  a) Chance for wind into 20s to 30-35 kts, but
  b) look out for gusts to 40-50 kts, mainly between 18 utc Wed and 060 utc
Thu
  c) Conditions rougher to N and NE closer to the low, while less to S and
SW
8) With the stronger winds, seas will be quite rough, possible to 15-20 ft
Wed night into early Thu
9) This low then tracks more E and will be N or NE of Azores early Thu AM,
while high pressure builds behind you to SW
10) Conditions improve during Thu, as this low continues to exit more E,
and the high builds to near 32n/40w by 00 utc Fri
  a) diminishing W-NW to NW breeze, down to 20 kts or less by later Thu or
Thu evening, but
11) The high continues moving E and will be located near 30n/20-30w during
Sat
12) North of this high, there will be a moderate/strong W to W-SW flow
approaching Azores during Sat
  a) Wind mainly in 20s to 30 kts

Routing...
1) Generally a direct route toward Azores, but
2) you may want to slow down to 5 kts or less to have better conditions
