All yachts of foreign registry must report. And all vessels entering within 12 nautical miles must report their presence by radio: VHF Channel 16, 156.800 MHz.
Immigration: Tourists and passengers arriving at Phuket by boats of various categories can process entry procedures for themselves and their vessels either at Phuket Deep Sea Port which is for international passengers, cargo and fishing vessels or Vessel Control Center, Chalong Bay for persons arriving by yacht or small sailing craft.
Important Notice for Captains and Crewmembers of Yachts: The Immigration Act of 1979 and subsequent Ministerial Rules of Enforcement stipulate the following:
Captains and crews arriving by boat in Thailand will be allowed to stay in Thailand up to 30 days.
All such persons are expected to leave on the same vessel they arrived on.
The law states that if they decide to leave Thailand by any other method, the permit to stay will automatically be cancelled, and they will be blacklisted from re-entering Thailand.
In order to avoid being blacklisted, captains and crews wishing to leave the country by any method other than the way they arrived must present all relevant documents at Immigration and submit a bond of 20,000 baht.
The deposit will be refunded once the Immigration Department received confirmation that the captain or crewmember has left the country. Immigration officers will be happy to offer guidance on the technicalities of these procedures.
