The Phinisi is a traditional Indonesian-style sailing yacht offering liveaboard dive holidays in Thailand, comfortably accommodating 18 divers. She boasts a spacious dive deck with plenty of storage space for all of your dive gear. The outdoor dining area at the stern is covered and shaded so you can fully take in the breath-taking views of Thailand and Myanmar. Every day, our chef prepares plenty of dishes from the famous Thai cuisine with fresh, locally sourced ingredients. Friendly and experienced, our boat and dive crew are there to meet your every need, making your diving holiday in Thailand unforgettable.

Liveaboards in Thailand are centered primarily around the Similan Islands, a chain of 9 small islands with white sandy beaches, located on the west coast of the Thai peninsula. Surrounded by the richest waters around Thailand, the diving in the Similans is without a doubt the best that Thailand has to offer. Diving here is all about the beautifully colourful reefs, sleepy leopard sharks, majestic mantas and frequent whaleshark encounters.

We recommend arriving by December 21st to acclimate and recover from travel. We invite you to stay on after the boat trip to celebrate the New Year in Phuket or Bangkok! Both locations offer an amazing experience and will celebrate the New Year in spectacular fashion. 

Transfer between Phuket Airport, or local hotels and The Phinisi on embarkation and disembarkation day are included in the liveaboard price for all departures.

  • Transfers from and to hotels and resorts outside of these areas can be arranged for an additional charge.

  • The following is a description of the dive sites that we may visit during your liveaboard.


    Similan Islands National Park

    The above water scenery will provide stunningly beautiful white sandy beaches with small forested areas. Dive some of the following sites; Boulder City, Sharkfin Reef, Anita's Reef and Three Trees. Under the surface you may see: Leopard (zebra) shark, blue spotted stingrays, clown triggerfish, rabbit fish, scorpion fish, snappers, emperor fish, giant trevally and angelfish. The coral gardens, bommies and boulder formations are wonderful to dive.

    Elephant Head Rock, visible from the surface, is the biggest pinnacle in the Similans and has some fantastic swim-throughs. White tip reef sharks, batfish, trevally and barracuda can often be seen on the perimeter of the boulders. If you look closely in the cracks and in the rubble you can see smashing mantis shrimp, porcelain crab, moray eels and cleaner shrimp.

    There are also sites dominated by huge granite boulders such as Deep Six, Christmas Point, and North Point where you can see white tip reef sharks, schooling giant trevally, and schools of neon fusiliers.

    Koh Bon

    This is generally the most likely place to see manta rays on this itinerary. You are also likely to see Napoleon wrasse, sweetlips, octopus, bluefin trevally, giant moray eels, great barracudas, fire dart goby, spiny lobster and nudibranchs of many types. The dive sites vary from wall diving to gently sloping reefs and from submerged boulders to coral gardens.

    Diving on the West Ridge can be an adrenaline filled drift, with amazing views, while the North Reef is a gentler experience over a hard coral garden.

    Koh Tachai

    This island is famous for its pinnacle dive site, known by many as Twin Peaks as well as more relaxed reef diving on the North Reef and South Reef. Normally, turtles, barracuda, pipefish, and nudibranchs can be found here. There is also a chance to see bigger species in this area like manta rays and whale sharks, especially by late January until April.

    Richelieu Rock

    This limestone pinnacle was named by Jacques Cousteau after Cardinal Richelieu due to the similarity to the colour of his gown as there are gorgeous purple dendronephthya soft corals covering most of the pinnacle. There are other areas covered in magnificent sea anemones as well. Barely breaking the surface at low tide, this horseshoe-shaped outcropping slopes steeply to a sandy bottom at 18 to 35 meters (60-120 Ft). This site offers great diversity for such a small and isolated spot. It also offers excellent multi-level diving and, because it’s a high-profile reef, there’s always sheltered areas to hide from current.

    The marine life is prolific and includes amongst, many other things; pharaoh cuttlefish, large octopi, all 5 varieties of anemone fish of the Andaman Sea, variety of moray eels, ornate ghost pipefish, smashing mantis shrimps, harlequin shrimps, tiger tail seahorses, spanish mackerel, frog fish, many schooling snapper and occasional sightings of manta rays and whale sharks.

    Surin Islands National Park

    The topside scenery of Koh Surin, with evergreen forests, mangroves, and small beaches, surpasses even that of the picturesque Similan Islands. Under water the reefs of Surin have some of the greatest hard coral diversity in Thailand. Across sites like Torinla Pinnacle, Hin Kong, and Turtle Ledges you are likely to see Napoleon wrasse, yellow-masked angelfish, bumphead parrotfish, tomato anemonefish and barramundi, as well as lots of turtles that still come ashore in this area to lay their eggs. Because of the remoteness not many liveaboard boats visit these islands and you will be able to enjoy the dive sites without sharing it with tourist hordes.

    Khao Lak Wrecks

    Before disembarking in Khao Lak, if conditions and timing are favourable there is a choice of easily diveable wrecks between the Similan Islands and the port of Tap Lamu. The Boonsung and The Premchai are old tin miners that were sunk in the 1990’s and are a treat for underwater photographers as well as lovers of life of all kinds!

    Only in 18m of water they are covered in nudibranchs and various kinds of shrimps. Many quite unusual honeycomb morays also made these wrecks home. There are also huge numbers of schooling fish as well as rays and sharks that can occasionally be seen. Sea Chart 1 is a slightly more challenging dive and lies between 40 and 25 metres. Sunk during a storm in 2009 with a full load of teak, she is relatively new but already hosts an abundance of schooling fish.

    Along the route there are some incredible views from the boat including verdant forests, deserted beaches, and limestone karsts climbing vertically from the ocean. There will be several opportunities to leave the boat and take a walk on the islands. A walk up the trail to Sail Rock is definitely time well spent! You can even be entertained by marine life while relaxing on board The Phinisi as dolphins cruising along with the boat are not an unusual sight.


    This itinerary involves some long distance travel and, while we attempt to ensure the number of planned dives is fulfilled, bad weather and sea conditions can affect the boat's ability to reach a specific dive site in good time and may impact on the number of dives that are possible.

    Safety and dive briefings are conducted in English.
