My recollection is Wind uses the GFS model where Wave use WW3. GFS is on 1/2 degree resolution where WW3 is on 1 degree resolution. It may be SailDocs supports combining both types, but once again the thinking is to keep the files small for low speed sat phone transmission. The advantage of using an email connection is the support for mid file restart in the event the sat phone connection is lost mid transmission. Sat phone rates are falling, but still not cheap.
