	Go to: http://www.emc.ncep.noaa.gov/ Select: GFS logo Under U.S.-No America select: "View more model forcasts" This takes you to "Model Analyses and Guidance" page. Select: "Model Guidance" Select an area (for SOL WR leg 4 select "Asia" Select a Model Type (start with "GFS") This will load page with "Available Model Cycles" For surface winds select "10m_wind_precip" That will load a box of colums with projected winds from 3 hours out to 384 hours out. Select any and a chart of the projected Wx for that day and hour will load. This can be saved as a gif file. From the chart page you can return to the Available Model Cycles page to select another time in the furture.

	Very helpful - thanks Jack... Be interested to look at some of the other models implied in your post - they can often be helpful when trying to predict how later winds will change from the current forecast I help develop the client interface for the best online ocean racing sim there is... __/)/)_/)__

	Are these published earlier than NOAA's grib file runs? Saildocs is also a good way of getting long range forecast. If you send the following to queryATsaildocs.com... Subject: anything you want Body: send GFS:40N,61S,40E,140W\|1,1\|0,6..336\|PRMSL,WIND ... you get the grib file for the specified area and timeframe in return. You can also subscribe... Subject: anything Body: sub GFS:40N,61S,40E,140W\|1,1\|0,6..384\|PRMSL,WIND days=0 time=23:00 interval=6 ... and you get this sent to you 5 min after each time interval starting from 23z tonight. (Saildocs runs subscriptions 5 min after every 1/2 hour and the full 384h run is normally finished by then).

Kamchatsky to Tromsoe 2024

Just before the light failed entirely in Antarctica, Skip Novak managed to get his Pelagic 77 out of the ice and north up the Pacific to Kamchatsky. The sun is shining (24/7) and not a penguin to be seen, and Skip believes the Norh East Passage is ice-free (sufficiently) to attempt it, so all aboard for a c 4250nm voyage from east to west across the top of Siberia, Russia and Norway to Tromsoe!
