Creating a zone and selecting weather, wave and current models is one of the first things to do to prepare a navigation.  But how to pick the ones you need when you’re just starting using Weather4D or if you are exploring a new area? Weather models in Weather4D

What kind of sailing are you up to?

Will you be cruising for several days without cellular coverage?  Low resolution like GFS may be best. Are you prepping for a race on a relatively short distance?   High resolution is more suited although it’s always a good idea to compare models.

What about routing?

Routing involves not only weather but also wave and current models.  It is important to combine them correctly because a wave model is calculated using wind as a parameter.  It is better for instance to pick MFWAM for waves when choosing WRF or Arome for weather.  Likewise, it will make more sense to use FNMOC WW3 Global with GFS.
