LuckGrib is NOT to be used for navigation!

You ALWAYS need to verify any path generated by LuckGrib with your navigation tools.

The LuckGrib base map does not contain any water depth information, there are no navigation aids, no traffic separation lanes, and so on. The weather routing solver will happily send boats across what could be shoal waters or across land it doesn't know about. The base map is missing small (and medium and large) islands. Some coastlines are grossly wrong.
