I sail 3-4 months a year, mostly in Greece where most sailors use your app with ECMWRF. However openWRF will show local winds not seen on your current models, like dangerous 50+ knt katabatic NE wind experienced a few time per month during high Meltemi wind.
For instance, Karistos bay (South Evia) should be well protected from high NE Meltemi winds with a 1000 m mountain protecting it. Yet, a few times a year like today Aug 4 2022 but also mid June and early July this year, 50-60 knots Katabatic winds are observed there while not forecasted in your current models. (Karistos 38° 0.783' N 24° 25.034' E)
A group of French sailors in Greece / météo enthusiasts have documented the ineffectiveness of current Windy models in those hot spots and the effectiveness of the Athens University project model openWRF 4 km.

Also, Windy App (blue logo) offers this model.
Thank you for considering.

If you read French here is a link of an extensive study. Bottom line only openWRF predicts this phenomenon

In Greece, we (and all the sailors we know here) use the ECMWF model as most granular and accurate.

We also compare short term forecast (48 h) to OpenWRF via OpenSkiron (a joined project between universities of Athens and Israel). I really wished Windy would integrate this model for this area (feature request as of last year … no luck).
