Is your feature request related to a problem? Please describe.
Weather_routing can use 30 year averaged ocean currents that are available in the Climatology data and it can use a second RTOFS grib which has gridded data for surface currents available. The problem is that the RTOFS data is not fully implemented for coastal areas. For example, the last I checked, the Gulf of Maine was not available.
At present, weather_routing does not use the point Tide/Current prediction information to interpolate gridded points..
What we need is a predictive gridded model that can be downloaded for near shore weather routing.
OFS appears to be headed in this direction. See this model.

Also see page 45 of David Burch's ENC Essentials booklet and his Youtube using luckgrib. Luckgrib current grib exported to qtVlm and used in qtVlm. Then compares this data to Noaa tidal current prediction data.
Describe the solution you'd like
An OFS gridded current model that can be downloaded and used in weather_routing.
We need the ability to download these grib data models directly.
