Did they add any form of functional nautical navigation? It always jumps to the nearest road on LAND. The feature should be removed if it doesn't work.

Any chance the profile you were using had the "snap to nearest road" option turned on? If that option was on for the profile then that would be why it jumped to the nearest road.

I've had the nautical navigation work fine when canoeing on rivers and streams where you're following linear features on the map. What it lacks is the ability to plot a sensible course across a polygon of open water.

Rumor has it that routers have the same issue with highway areas so best practice is to add a "spine" to them

The presence of such spines in open bodies of water just makes nautical routes come out particularly stupid, where the route presented calls for you to immediately go to that spine and travel along it, unnecessarily lengthening the route.

Same problem for pedestrian plaza structures btw. Though there it's arguably worse as it has a good chance of affecting routing choice not just user presentation.
