Thai boats near the berth on about. Phangan (Koh Phangan). Are on a leash so carry tourists around the island. Boats as boats, punts, but that's engines - things interesting. Motor boat - it's automotive diesel engine, adapted to cool water from the ocean. From mechanisms thrown out gearbox, clutch abandonment and gas on the handle removed. Chase these boats is excellent, but a storm to walk on them - scary.
