On OSM, it shows a ferry route between Montserrat and Nevis. This also exists as a way (Way: Montserrat-Nevis (1243741932) | OpenStreetMap). However, when I try to route it walking between the ferry terminals, it says that there it couldn’t find a route between them on all three engines. Could someone help?
This seems also to be a problem with many ferry routes, e.g. St. George’s to Carriacou
