The Moken (aka Salone, sea gypsies) are a seminomadic seafaring culture that live off the fruits of the Andaman Sea. They have their own ways and religion and live for 8 months or so in boats, returning to land during the rainy season.
Here is a Moken village on Bocho island. Nomads living in a village is rather contradictory—they are still seen living in their boats among the islands but through some series of events unknown to me, involving a combination of population and the government, some live in this spartan village headed by a buddhist monk/former army colonel.
