The long-tail engine clicks to life and the sea answers, pushing the boat out of Old Town Pier as limestone cliffs shrink into the rearview. Sun hits the Andaman like a sheet of glass; the guide trims the motor and the boat drifts toward a string of small islands whose names are spoken like directions to a secret — Koh Chuak, Ko Muk, Koh Ngai, Ko Maa.
