The plugin is just part of why OsmAnd is good for nautical use, there is also an alternate view in the configure map menu for nautical use.

For some reason osmAnd was the only GPS map that would work on a flight for me.

OM and CoMaps should also work, though you might need to wait awhile for a GPS fix and be near a window. Google's main hiccup will be an internet connection for the maps.
