Around €11 per person, which is a quarter of what a tourist catamaran of the same length would charge. It is subsidised because Lastovo is remote and people live there.
Boarding is at Ubli, the ferry port on the west of Lastovo, not in Lastovo village itself — those are ten kilometres and about fifteen minutes apart, and there is no bus at four in the morning.
Seats are rarely a problem at that hour, but book anyway: it is one boat, and if it is full there is no second.
