I have trouble remembering if Gosmore currently supports the maxspeed
tag. But if it does then that tag could be 'abused' to give Gosmore a
realistic hint about the traveltimes of ferry's. We could set the
default for ferry's higher to (say 20km/h) and let the maxspeed
represent the time it takes to take the ferry route.
