You can get 3 hour intervals through Saildocs. The following request is a long range forecast that works fine with a highspeed connection:
send gfs:12N,60N,130W,50sW|1,1|00,03..300|PRMSL,WINDS
it will never work of course through sailmail
The original post was just me being lazy and liking the ability to just define a box instead of looking up L/L parameters etc
The rotfs part comes from looking at the following rotfs file:
send rtofs:44N,18N,80W,50W|0.1,0.1|0,12..144|
In that you'll notice two huge eddies between Bermuda and ST. Thomas that relative to gulfstream speeds could be what, maybe 4-5 knotts. The grib window in MacENC is geared for windspeed but it would be nice to have a surface speed scale of some sort tied to the current arrows if possible. Thirty years of running that route and I've never seen eddies that big in that area!
Cheers, Robert
