The devil is in the details. The shapes of weather systems are based on data, as are the wave height estimates, but when you project it into the future it is at best an educated guess.

Yes GRIBs are a FORECAST!! How is that a limitation? The computer fantasies use measured initial conditions and project into the future. It is the origin of all weather forecasts as far as I know.

Additionally, off shore the big picture provided by the GRIBs was more sufficient for navagation, local conditions were not of interest. You just want to know where the big lows are tracking two to three days out so you can manuver for better postion.

Re: Atlantic Delivery

GRIBs are OK but usually not as good as when a human forecaster gets involved. Personally I prefer a good old fashion weather fax.

Re: Atlantic Delivery

Thanks folks again don't want to derail the thread, I understand the limitations of forecasts, they're not even all that accurate 3-5 days out when forecasting for the local area, so offshore and away from direct observation has to be WAY more challenging.

The posts with boatie's position and what happening around him have been pretty cool from my perspective. As would an understanding of what info he actually has available to him on passage. Can't wait to hear what actually happened and the why's behind his route changes. So far this is one of my favorite CF threads.

Now back to our previously scheduled broadcast...

Re: Atlantic Delivery

Well the more you sail offshore the more you realize that forecasts are often not accurate.

Re: Atlantic Delivery

my guess is boaty has no weather forecasting aboard. I don't think he would buy a spot if he had a satphone or HF radio. I think he would have downloaded a 9 day forecast and is doing his best to position himself with that information as well as witht he weather he is seeing., i.e., head to the edge of the Azores high and follow up the NE's
The new owner is a CF member, he may be able to shed some light if he is reading this thread

Re: Atlantic Delivery

Perhaps the new owner had the equipment?

Re: Atlantic Delivery

Most have seen this but for those that haven't its kinda cool to see the big picture and get an idea in real time.

earth :: an animated map of global wind and weather

Top is currents and bottom is wind.

I'd be surprised. Few people would take such a dramatic course change without a clear perspective of what the purpose is. You don't go chasing around the Atlantic looking for the " right " wind by chance

Re: Atlantic Delivery

well a spot probably cost Phil about $500, which is equivalent to 2000 cigarettes or 1000 cigarettes and 100 beers, so Im thinking unless it was essential equipment (for safety SOS or emergency SMS) theres no way in the world Phil would fork out just to keep us amused with his progress...
I may be wrong, he may be planning a Movie!
Its also possible a passing ship said 'where the hell do you think you're going' about 3 minutes before he turned South
