Pick a direct departure. The same 700 baht buys a ninety-minute run or one of over three hours with a change at Koh Phangan, and the timetable marks the difference with nothing more than an asterisk.
Speedboat or catamaran
The 08:00 and 14:30 from Maenam and the 15:30 direct speedboat from Bangrak take ninety minutes. The 08:00, 11:30 and 14:30 from Bangrak change onto a catamaran at Koh Phangan and take two to three and a quarter hours for the same fare.
Ferry
Lomprayah's larger, slower boat, for 150 baht less than the fast ones.
The season changes this. The northeast monsoon runs down the Gulf from November to February. These are the months the crossings are roughest and the occasional sailing is cancelled; from March to October the sea is usually easy. Book something you can move by a day if your dates sit in the rough months.
These times and fares are read off the operator's own published timetable, not an agent's. Gulf timetables change with the season and the sea, so confirm before you build a day around a departure. Last read on 2 October 2026, from Lomprayah's 2026 timetable (PDF) and Lomprayah.
