IMHO you can tag this either on the ferry lines (ways) or on the
relations, but if you do it you will have to have a distinct object
for each line / all lines that share the same properties, i.e. you
might have to add more objects (relations/ways) in order to tag the
travel time.

why would you want to make a "master relation"? Relations are not categories.
