GFS:22N,08N,088W,073W|1,1|0,24..120|PRMSL,WIND
AXNT20.KNHC this is URL: http://weather.noaa.gov/pub/data/hurricane_products/atlantic/weather/discussion.txt

Spotforecasts from saildocs
spot:21N,86.5W
spot:16.25N,86.50W

Would also add carib buoy and gulf buoy to the list
This is pretty much what I see everyday, and what can be had without a connection

I'd listen to Chris Parker if he didn't come on at the same time as the faxes

Check out the difference between looking at a GFS file and a COAMP file
Rather than Query SailDocs with GFS
Type in - COAMPS:18N,15N,089W,085W|0.2,0.2|0,6..72|PRMSL,WIND
Coamp
