Where these numbers come from
Places, coordinates, operators, which operator serves which pair, and every distance on this page are real and come from open data. Where a corridor has a filed timetable the departure times are real too, and ferry fares are the prices the operators publish themselves.
Derived from service area No carrier record names this exact pair. The operators listed publish a service area covering both places at a distance their mode plausibly carries people, which is evidence that the corridor is served and not evidence of a specific service. Pages state which, because presenting the two as the same thing would be dishonest.
Where no operator publishes a fare for a corridor, the price here is our own estimate, worked out from the real distance and the real operator through a fare curve that follows lead time, day of the week and season. It tells you roughly what the journey costs. It is not a seat anyone has agreed to sell, and the payment step will not take it.
