Ive sailed the Panamanian Caribbean coast for the past 6 years and know the current patterns here. I recently displayed Marine Currents via Windy for the Panama Caribbean coast and they were wildly innaccurate. The only model available for currents under Windy is apparently NESDIS... and it is WAY wrong here at least (180° wrong on much of the coast). Copernicus is much closer to reality here.
My suggestion is to make multiple current models available as is done with weather models.
