Highlights

  • Underwater photographers will be thrilled by the abundance of marine life while diving from the Thailand Aggressor.
  • Thailand, renowned as "The Land of Smiles" for its hospitable locals, offers divers on our liveaboard scuba diving trips an unparalleled experience in the Andaman Sea.
  • Explore renowned dive sites in areas like the Similan Islands and Richelieu Rock, where the crystal-clear waters teem with tropical fish, majestic manta rays, and the magnificent whale shark.

About Thailand Aggressor

The Thailand Aggressor opens up the Andaman Sea's most remote corners — from the Similan Islands and Richelieu Rock to Pulau Weh and the scattered islands of Myanmar's archipelago. These are the waters that earned Thailand its name as “The Land of Smiles” above the surface and a world-class reputation below it: clear water, reefs busy with tropical fish, and seasonal encounters with manta rays and whale sharks.

At 35 metres long and 7 wide, she carries just 16 guests across 8 cabins, so the diving never feels crowded. Built in 1977 and refitted in 2013, the boat pairs serious dive logistics with real comfort — a Jacuzzi on deck, an onboard massage therapist, and complimentary beer and wine once the tanks are stowed. Nitrox and full equipment rental are available on board, both at additional cost.

The diving

Two seven-night itineraries run round-trip from the Andaman coast: the South Andaman Sea route from Panwa Pier and the North Andaman Sea route from Tap Lamu Pier, each fitting in around 26 dives over the week. Below the surface you'll share the water with barracuda, Napoleon fish, eagle rays and sting rays, whitetip reef sharks, seahorses, tuna, octopus and an endless cast of nudibranchs.

On board

Every trip is full board, with all water, tea, coffee, juices, soft drinks and between-dive snacks included, alongside weights, tanks and the guiding of an experienced dive team. Round-trip airport transfers are arranged on arrival and departure days. The optional SeaGrass Grow carbon-offset program and any e-learning fees sit outside the trip price.

With a perfect 5.0 guest rating and 100 scheduled departures priced per cabin and per date, there's a trip to fit most calendars — check the dates below to find yours.
