About the Seudamgo Trimaran


The Seudamgo trimaran is a passenger vessel operated by Seudamgo, a ferry company running boat and transfer services between the eastern Gulf of Thailand mainland and the islands of Koh Chang, Koh Mak, and Koh Kood. A trimaran has three hulls, which generally gives it added stability compared with a single-hull boat, making it a common choice for open-water island crossings.


Where the Seudamgo Trimaran Travels


Seudamgo runs services linking Trat with Koh Mak and Koh Kood, as well as connections to and from Bangkok, Pattaya, and Suvarnabhumi Airport. Depending on the route you choose, your journey may combine the trimaran crossing with a road transfer to or from the pier.



  • Trat to Koh Mak and Koh Kood

  • Bangkok to Koh Chang, Koh Mak, and Koh Kood

  • Pattaya to Koh Mak and Koh Kood

  • Suvarnabhumi Airport to Koh Mak and Koh Kood


For a closer look at one of these crossings, see the Trat to Koh Kood ferry route or the Bangkok to Koh Chang ferry route.


Onward Transfers


Because piers serving these islands are not always close to major towns, Seudamgo also operates road transfers by minivan and songthaew to connect passengers between hotels, the airport, or bus terminals and the pier. Check your chosen route to see whether a transfer is included with your trimaran ticket.


Booking Your Seudamgo Trimaran Ticket


Departure times, journey duration, and fares vary by route and season, so it's best to check the specific route page for up-to-date details before you travel. Booking in advance is recommended, especially during peak travel periods to Koh Chang, Koh Mak, and Koh Kood.

Frequently asked questions

How do I unlock my account now?

Wait, and try again. Every lock lifts on its own — a minute the first time, and never more than an hour however many attempts have failed. There is nothing to click and nobody to contact.

If you have forgotten your password, do not keep guessing: each wrong attempt makes the next wait longer. Use Forgot password instead. Resetting your password gets you straight back in.

My account locked but I never tried to sign in

Then someone else was trying to sign in as you, and the lock did its job — it stopped them.

Your account is safe: a lock means the attempts failed. Nobody got in. You do not have to do anything, and the lock will lift on its own.

We would still recommend two things:

  • Change your password, especially if you use the same one on another website.
  • Add an authenticator app in your account security settings, so a password alone is never enough to sign in as you.

If you get these repeatedly, contact us and we will look into it.

What is the difference between a locked and a blocked account?

Locked is automatic and temporary. It happens after repeated failed sign-in attempts and it lifts by itself — within a minute in most cases.

Blocked is a decision made by our team, and it does not lift on its own. If your account is blocked you will need to contact us; waiting will not change it, and neither will resetting your password.

If you are not sure which applies to you, get in touch and we will tell you.

Why is my account locked?

We lock an account for a short time after several failed sign-in attempts in a row. It is an automatic safety measure: it stops someone else guessing your password, and it happens whether or not the person typing was you.

You do not need to contact us. The lock lifts on its own — see How long am I locked out for?

How long am I locked out for?

The first lock is one minute. If sign-in keeps failing after that, each further lock lasts longer:

  • 1st lock — 1 minute
  • 2nd lock — 5 minutes
  • 3rd lock — 15 minutes
  • 4th lock and after — 1 hour

An hour is the longest you will ever be locked out. You get five attempts before the first lock, and as soon as you sign in successfully everything resets — the next time you mistype, you start again at one minute.

How can I get transportation to the Pier (Phuket) from the airport?

You can pick up a taxi from the airport just outside Phuket airport terminal, though please be informed it is a busy place! 

 

Alternatively, you can organize your transfer through us on step 2 of your ferry booking process. The prices are very reasonable. For up to 3 people we have private taxis and for groups of 4-8 people, we can arrange a minivan pick-up service.
