The passenger doesn't care; his bus is always there!
And, as an added and revolutionary fbb suggestion, it might be an idea to have copies of a combined bus and ferry timetable available available in the Tourist Office and at Calmac's Largs Pier ticket office. For a minuscule fee, fbb will produce a nice PDF files for someone at Largs to print out. Indeed, here is the fbb version of part of the summer timetable; created absolutely free of charge.
And perhaps the sainted Traveline might consider giving out some useful and understandable information at the same time.

Public transport is straightforward by comparison!
