@Ondřej-Šutera Thanks for the reply. Offline won't work for a 5 day offshore race. We need weather updated regualrly.

Re: White list - fire wall
Hi Ivo, we have an Iridium GO! Exec that we want to use for offshore for races - such as the Sydney to Hobart. I would like to use Windy but due to the high cost and our data limit on satellite time, it's very important to set up the profile on the "exec" terminal to block all traffic except for the app we want to use.
Do you have a set of IP addresses for the Windy Servers that we can whitelist?

@korina Does the Currents view provide the Net effect of both wind driven and tidal driven flows? If not - this would be a highly valuable addition to enable better passage planning.
Similarly, does your Wave Model take the effect of Wind driven currents AGAINST tidal driven currents into account?
