MV Gentle Giant is the perfect Thailand liveaboard for divers who want to visit all of Thailand’s best dive sites. The boat was totally renovated in 2017 and it has ten clean & comfortable guest cabins, plus air-conditioned & outdoor communal areas. The crew & dive staff are all experienced, knowledgeable, patient & friendly. The food is delicious, and the itineraries are unique. It really is a great choice for liveaboard diving cruises in Thailand.

During the high season, Gentle Giant sails at night and you wake up at a world-class dive site out at sea. New for 2023-2024 Gentle Giant starts from Khao Lak or Phuket, depending on where teh previous trip ends. There are also two slightly-different itineraries. The 5D/5N trips go to Similan, Richelieu, Koh Phi Phi and Phuket. The 6D/6N trips also add Koh Haa and Hin Daeng. You can read more about the itineraries by scrolling down.

The ten cabins on Gentle Giant all have air conditioning, a private en suite bathroom, mini safe, and windows & doors which open out onto the deck. On the upper deck is the master cabin, which has a large double bed as well as a single bunk, but is only sold to two guests unless there are three who are in the same family. At the front of the main deck is the deluxe double bed cabin that might look small in the photos, but actually is the width of the boat! There are eight standard cabins, which have bunk beds. Two standard cabins are on the upper deck and six are on the main deck.

Between dives, most guests spend their time on the upper deck. Here there is a large outdoor dining area, which gives panoramic views of Thailand’s Andaman Sea. There’s also a large indoor air-conditioned lounge saloon. Here, guests can show or view photos or videos of the day’s diving or watch a movie on the huge tv, or just take a break from the sunshine. There is also a large sundeck, where you can enjoy the sea breeze and top up a suntan, or gaze at the stars during the evening.

Delicious meals are served buffet style on the upper deck. The food is a great blend of Asian & western cuisine that’s not too spicy. If you have special dietary needs, this is fine but please let the team know in advance. Fruits, snacks, soft drinks, tea, coffee & water are always available for free. Beer is available for reasonable prices, but only after your final dive each day.

Gentle Giant’s dive platform is large and well organised. At the start of each trip each diver is given a ‘tank slot’ and this is where your gear remains for the trip. Nitrox blending and the compressor work quietly to fill tanks quickly but not disturb guests. Gentle Giant is large enough to be safe, & comfortable. There’s a full complement of safety & communication equipment, as well as a motorized dinghy.

Booking / Enquiry

New for 2023-2024, Gentle Giant offers two similar itineraries, which can be identified by their length. Also the boat uses two different piers.

The regular trips are 6D/6N and they visit The Similan Islands, Koh Bon, Koh Tachai, Richelieu Rock, Koh Phi Phi, Phuket, Koh Haa, and Hin Daeng/Muang.

There are also a few slightly-shorter trips during the season. These 5D/5N trips go to The Similan Islands, Koh Bon, Koh Tachai, Richelieu Rock, Koh Phi Phi and Phuket.

Some trips start in Phuket and end in Khao Lak, and other trips go the other way, starting in Khao Lak and ending in Phuket.

More details are available below this text.

The itineraries below are the most-common for each trip, but these can sometimes be changed for a number of reasons. Small changes are made due to weather & sea conditions, special marine life sightings, overcrowded dive sites, local-authorities' instructions, and the needs & requests of the paying guests. The safety & comfort of all guests is most important at all times.
