Lomprayah catamaran service offer ferry and bus services. You can book them once on Koh Tao.
Thanks Lushlynds :) Do you know the time table for that journey???
I don't know the schedule for the whole journey but in all likelihood you will depart from Koh Tao on the 06.00 catamaran.
Andy's correct with the ferry departing at 06.00 with an expected arrival in Koh Lanta to be 14.00.
