The Manta Queen 6 liveaboard offers dedicated 4-night cruises to the Andaman Sea's most celebrated southern dive sites. This route takes in Koh Haa's labyrinthine limestone chambers, the legendary pinnacles of Hin Daeng and Hin Muang, and the vibrant reefs around Koh Phi Phi. It also includes the King Cruiser Wreck and Shark Point, two sites that have earned their places on every serious diver's list. The result is a varied and consistently rewarding week of diving, suitable for a wide range of experience levels.
The Manta Queen 6 is a comfortable 25-metre vessel with air-conditioned twin cabins with semi-ensuites, a spacious diving platform, and a relaxed indoor dining area. The vessel accommodates a maximum of just 12 guests, a deliberate choice that creates a noticeably more spacious and relaxed atmosphere than you find on larger liveaboards. With a maximum of 4 to 5 divers per dive guide, you are not competing for space at a cleaning station or waiting your turn to peer into a swim-through. The experience is personal, and the crew have the time to attend to individual needs, whether that means help with kit or advice on a particular site.
The Manta Queen 6 liveaboard is operated by a company with over 20 years of experience in the region. They run a fleet of well-regarded vessels and employ more than 50 SSI professionals, many of whom speak multiple European and Asian languages. This depth of local knowledge is evident in the way the trips are run, from the timing of dives to the choice of sites on any given day.
The Manta Queen 6 crew's reputation for good food and attentive service is a recurring theme in guest reviews. The chef prepares a mix of Thai and international dishes, with fresh fruit and snacks available throughout the day. The galley is flexible with dietary requirements, and the use of MSG is avoided. After a day of diving, the atmosphere on board is easy and sociable, with guests swapping stories of manta rays at Hin Muang or leopard sharks on the sandy patches near Shark Point. For divers looking to explore the southern Andaman Sea in comfort and with a knowledgeable team, the Manta Queen 6 is a compelling choice.

Day 1
Board at Coco Pier, Phuket, from late afternoon. Settle into your air-conditioned cabin, get your dive gear set up on the deck, and join the crew for a full safety and itinerary briefing. A light Thai supper is served as the Manta Queen 6 liveaboard slips its lines and cruises south toward the Koh Haa islands.
Core Days
The southern Andaman Sea itinerary of the Manta Queen 6 is a masterclass in contrast, moving from deep, oceanic pinnacles to sheltered limestone walls and one of the region's most famous wrecks. Your first encounters are at Koh Haa, a cluster of islands where clear water and dramatic underwater topography set the scene. Swim-throughs and caverns open into chambers lit by shafts of sunlight, home to glass-eyes and schools of fusiliers. Moving south, the boat points toward the open ocean for Hin Daeng and Hin Muang. These two submerged pinnacles rise from depths beyond 60 metres, their sides draped in soft corals and gorgonian sea fans. The upwellings here draw pelagic fish and, with luck, manta rays cruising the cleaning stations. Whale sharks pass through these waters too, though as with any wild encounter, timing is everything.
From the deep blue, the tour shifts to the shallows of Koh Phi Phi. The islands' limestone karsts drop beneath the surface to create overhangs and gullies thick with marine life, a more sheltered contrast to the open-water dives. Then there is the King Cruiser Wreck, a large car ferry that now rests on its side, its hull colonised by thousands of fish and draped in anemones. The final dive is at Shark Point, where the reef is famous for its purple soft corals and the leopard sharks that rest on the sandy patches beneath the overhangs. Between dives, the sun deck offers a place to lie back and let the miles pass, while the crew serve freshly cooked meals and keep the snacks coming.
Day 5
The last morning opens with an early dive, typically at the King Cruiser Wreck or Shark Point. After breakfast, there will be a second dive then the Manta Queen 6 heads back toward Phuket.

The Manta Queen 6 liveaboard crew manages the logistics, leaving you free to focus on the diving and the company of fellow travellers. Meals provide the punctuation points between dives, served buffet-style in the open-air dining area on the upper deck. The kitchen crew takes pride in their work, and the standard of the food regularly draws positive comments from guests. Special dietary requirements, including vegetarian and vegan options, are catered for with advance notice, and the use of MSG is banned across all trips.
Mornings start early on the Manta Queen 6. A wake-up call comes at 6 am, with the first dive briefing following shortly after. The idea is to get in the water before the day warms up and the wind picks up, taking advantage of the Andaman Sea's calmest conditions. After surfacing from that first dive, breakfast is served. Alongside the familiar spread of eggs cooked to order, sausages, bacon, and hash browns, you might find khao man gai, the Thai-style Hainanese chicken rice served with a piquant garlic and chilli sauce. For a lighter start, khao tom, a savoury rice soup with pork or shrimp, warms you from the inside. Fresh pineapple, watermelon, and dragon fruit sit alongside yoghurt, muesli, and toast with spreads. The drinks table holds coffee, tea, and fruit juice.
Lunch and dinner rotate daily, showcasing the kitchen crew's broad expertise in regional Thai cooking. One day you might be enjoying khao mok gai, a Thai-style chicken biryani with a cooling cucumber salad, or gaeng hung lay, a Burmese-influenced northern Thai pork curry with ginger and pickled garlic. Seafood lovers might find goong pad nam prik pao, prawns stir-fried with chilli paste and long beans, or tom yum goong, the iconic spicy-sour shrimp soup with lemongrass and lime. Noodle options include kuayteow reua, a robust boat noodle soup with dark soy broth and beef. Salads bring brightness: yum pla duk fu combines crispy catfish with green mango and chilli. For those who prefer a taste of home, there are always western options available.
Desserts are far from an afterthought. Tub tim grob, 'red rubies' of water chestnut in sweet coconut milk, appears regularly, alongside khao niaow ma muang, the iconic mango sticky rice when the fruit is in season. Fresh coconut jelly and slices of ripe papaya round out the meal. The galley keeps a steady supply of salted peanuts, prawn crackers, and seasonal fruit between dives. Soft drinks, juice, tea, and coffee are always available, and there is ice cream for those wanting a cool pick-me-up after a dive.
When the weather obliges, the crew hauls the barbecue onto the sun deck. The evening might bring whole grilled fish with lemongrass stuffing, moo ping (grilled pork skewers), and gai yang, Isaan-style grilled chicken served with sticky rice. If the wind turns, the barbecue moves into the sheltered dining area, but the relaxed, sociable mood holds firm.
