The Lomprayah high speed ferries are large catamaran style boats with powerful marine turbines. Journey times will depend on the weather and departure point and whether the sea is a little choppy or calm. The direct route from Chumphon to Koh Tao can take 90 mins or less via Koh Nangyuan island or 5 hours from Surat Thani, stopping at Koh Samui and Koh Phangan. Lomprayah from Koh Samui will stop for 10 minutes for passenger exchange at Koh Phangan and takes approximately 2 hours.
