The Deep Andaman Queen is a much-loved Thailand liveaboard service which has been part of the Thai diving scene for many years. In fact, it’s undergone something of a renovation in recent years. As such, it’s now one of the biggest and most luxurious boats offering diving fun across some of the country’s fantastic scuba diving spots.
The Deep Andaman Queen travels across the stunning Similan Islands, taking you to Koh Bon, Richelieu Rock, Koh Tachai – great for spotting rays, sharks and more. And, as you’d expect, this well-known cruise also checks out the Andaman Islands and its famous dive spots.
The crew on board at the Deep Andaman Queen works incredibly hard to offer you the best time and access to the best dive sites across the Similan Islands. Take time to relax in roomy cabins with full dining suites, and all the diving support you’ll need to get closer to local marine life.

More expensive than other Thailand liveaboards on this list the Thailand Aggressor is a truly massive Thailand Liveaboard, offering scuba diving convenience for experienced divers and deep sea novices alike. You’ll have fantastic access to the North Andaman Sea throughout the year.
As a truly huge Thailand Liveaboard at 35m, this incredible scuba diving experience offers plenty of space for up to 16 guests, as well as five optional dives throughout your days on board. When you’re not busy taking the time to spy leopard sharks, reef sharks and manta rays, you’ll be able to kick back and relax in your own roomy, luxury state room.
This Thailand liveaboard experience is likely to be more expensive than the other choices on my list. However, this is understandable – you only have to look at the extensive diving options and luxury suites available to understand you really get what you pay for. And in this case, it really is one of the best.

Hop on board this incredible liveaboard built like a traditional sailboat! The Phinisi is a classic liveaboard option which will take you across some of the best-loved dive sites that the Similan Islands have to offer. Comfortably welcoming up to 18 guests on board, this spectacular liveaboard offers full dining suites, in-room air conditioning, and an experienced and attentive crew. There are dive guides available on this Similan Islands liveaboard, too, meaning that if you are relatively new to scuba diving, help is always going to be on hand.
You’ll have access to plenty of diving storage, as well as equipment and shaded deck launches for when you need
them. What I really like about the Phinisi is that it’s one of the best diving experiences that you can customise. There are several dives off this liveaboard which take place each day, and you’ll be able to tailor your dive holiday between four and ten nights as you desire. There are also plenty of cabin options you can tweak best to fit your budget, too.

The Bavaria liveaboard is one of the most intriguing scuba diving holiday options available for people visiting the crystal clear waters of Thailand. It’s a vessel which was actually built by divers, meaning that you already know you’re looking at a custom boat that will attend to your scuba diving needs.
Beyond that, this liveaboard travels to some of the most stunning locations and diving sites across the Andaman Sea and beyond. You’ll have the choice to explore the colourful Similan Islands, Richelieu Rock, Koh Bon, the Surin Islands, and even the hidden Mergui Archipelago – a rare treat for anyone who may have been on Thailand liveaboards before.
You can also check out the Shark Point and more with a scheduled diving trip to Koh Phi Phi.
Of course, you can also expect a lovely, welcoming stay on board the vessel itself, with a full crew and instructor team. You’ll also find there’s lots of equipment to hire, and you can even arrange for a massage or two after a long dive. Why not?

Hallelujah is a superb Thailand liveaboard, offering tours around the best of the Similan Islands while ensuring you are comfy and well air-conditioned when you come back from your dives. There are luxury cabins available here, and what I especially like is the fact the holidays on board are largely charged at a flat rate. They might be a little more expensive than some of the other liveaboard options in Thailand, but are well worth taking advantage of.
This is a truly massive liveaboard! It easily welcomes 25 people, and has a huge array of entertainment and relaxation options. Therefore, you’re likely to have plenty of room to stretch out after a long day of scuba diving.
Hallelujah also benefits from having amazing dive staff! The friendly, English-speaking crew won’t just make sure you have everything you need for your dive trips, they will also make sure they are clean, ready and prepared for you when you next dive down through Elephant Head Rock, for example!

In the meantime, here is a quick selection of some of my favourite dives to wet your appetite.
Hin Muang and Hin Daeng
This is a great dive location if you’re looking to see leopard sharks up close and personal. However, it’s also likely to be a great spot for exploring some of the most complex and visually stunning underwater swim throughs. However, do make sure you have a competent dive leader down here with you and that you do so with a bit of experience behind you!

The Similan Islands

These wide open waters take you up across the Andaman Sea, where you can spot all manner of sharks and rays. There’s also the Similan National Park here for you to explore, too. Make sure to book a liveaboard Similan Island bound if you want to see some of Thailand’s most stunning undersea landscapes up close and personal.

Get on board a Thailand liveaboard and experience it all with a dive team.
