yes

Apparently it is considered as an option, but the route still takes the Tanger-Tarifa ferry, because it is assumed to be faster.
In OSM Tanger-Tarifa link is mapped with duration=0:35 while Algeciras-Tangier Med is mapped with duration=1:30.

how can we force the API to take the Algeciras-Tangier Med ferry, we need it to take the algeciras-Tangier Med, as it is the one that supports the big trucks transpotaion

from graphhopper.

You should be able to use a via-point in the middle of the sea like this: https://graphhopper.com/api/1/route/profile=car&point=35.85323,-5.53651&point=35.971832,-5.436935&point=36.132057,-5.461992

This does not work on graphhopper.com/maps because snapping to a ferry is avoided. When using the API you have to make sure you are not using snap_preventions=['ferry'].

But regarding the problem: Are you saying big trucks are allowed on one but not the other ferry? This can be mapped in OSM.

from graphhopper.

yes they are not allowed on Tanger-Tarifa. how can we map it in OSM?

from graphhopper.

OSM supports different kinds of vehicle restrictions like maximum weight, length etc. Some of this is documented here: https://wiki.openstreetmap.org/wiki/DE:Key:access
If you don't know it is best to get in touch with the OSM mapping community. You could for example contact the users that created/edited these ferries.

I'm closing here since this is rather a mapping issue. For further questions related to using GraphHopper please use our forums.
