Ferry Routing NCN3

NCN Cycle Route 3 in Cornwall includes a crossing on the King Charles Ferry on the B3289 near Feock. OSRM router routes via the Ferry, but Graphhopper does not, sending the route several miles North to avoid the river. Map Matching fails saying the Sequence is Broken.

I’m a bit of a novice, but managed to update some of the tags, as it didn’t allow cars or motorcycles, but bicycles were always permitted and is was also tagged with NCN3. Is there anything else needed?
