Can Foreign Nationals Register a Yacht in Thailand?
Yes, a foreign national can own 100 percent of a yacht and register it in Thailand under their own name. The one requirement that trips people up is establishing a registered address in Thailand, which is necessary before the registration process can move forward. Island Spirit can help you obtain a registered address in Thailand. Once that's in place, foreign ownership and registration is a straightforward path, and it's one of the reasons Thailand remains an attractive base for international yacht owners. Understanding the registration categories and documentation requirements ahead of time makes the whole process go more smoothly.
Understanding Registration Categories and GRT
The primary registration category applied to a yacht in Thailand is Sports and Recreation, which only applies to privately owned vessels and cannot be used for business or commercial operation. Yachts registered under this category can move freely within 15 nautical miles from shore and travel between provinces without needing to inform Harbour Masters along the way. There are some restrictions to keep in mind, including the requirement for an assigned skipper, and the need for inspection and permission documents before leaving Thai waters. Thailand also uses GRT, or Gross Registered Tonnage, to measure vessel size for registration purposes, which is a measure of available volume rather than displacement, length, or weight. For reference, a 45 foot sailing keelboat comes in around 8 GRT, while a 45 foot catamaran is closer to 23 GRT.
Documentation Required to Transfer Registration
Transferring a yacht's registration from Seller to Buyer involves documentation from all three parties in the transaction, the Broker, the Seller, and the Buyer. From the Broker's side, the original Purchase and Sale Agreement is required. The Seller needs to provide three copies of their passport, including the data, visa, and departure card pages, along with a residency letter from Thai immigration, several Powers of Attorney for the Sale Agreement, Revenue Department, Tax ID, and Harbour Department registrations, a Tax ID Number, the original yacht registration book, and photos of the yacht from both sides. The Buyer needs a similar set, including three passport copies, the same set of Powers of Attorney, a residency letter, and a Tax ID Number. All copies need to be signed in blue pen specifically, which is a small but important detail that's easy to miss.
Fees and Key Terms to Know
The Revenue Department charges a stamp duty of 0.5 percent of the purchase price for the Official Bill of Sale, with agent fees determined on a case by case basis. A residency letter is issued by Thai immigration to confirm a registered residential address, and it stays valid for the duration of your visa, though you'll need at least two weeks remaining on that visa for the registration transfer to go through. A Tax ID is required for boats over 5 Gross Tonne for Revenue Department registration and stamp duty purposes, and both the Buyer and Seller need their own Thai Tax ID. Power of Attorney is the document that gives someone the authority to sign documents and submit or receive paperwork related to the registration transfer on your behalf.
