Yes, I was disappointed that the "bus" routing option appears to be for driving a bus. The Valhalla pedestrian routing engine does include ferry routes, though it completely ignores ferry schedules. (Ferry use can be discouraged in the routing options... the interface for fine-tuning options for the different routing profiles is quite impressive. )
