The claim that the journey would be for little over an hour and a quarter is a downright lie or the gibberish of an imbecile. Anyway, all those Thai were only there because it was free.
In the '90s before the Samui airport was built, an Australian group formed Royal Jet Ferries as they had identified the Surat Thani/Samui route as one of the world's most promising and proposed 45 knot 350 passenger monohulls for the venture. These vessels were already running successfully in Malaysia, Singapore and Indonesia and could easily handle 4m. waves.
