About the Manta Queen 3
The Manta Queen 3 is a steel-hulled dive vessel designed specifically for liveaboard diving in Thailand’s Andaman Sea. Operating primarily during the Similan season, the boat runs scheduled Similan liveaboard itineraries that cover many of the region’s most established dive sites.
At around 35 metres in length, Manta Queen 3 offers a stable platform for multi-day diving trips. While the overall style of the boat is simple, it is laid out to support an efficient dive routine, with space for equipment storage, briefings, meals and relaxation between dives.
As part of the Manta Queen fleet, the operation is geared towards volume and consistency rather than boutique experiences. Among the fleet, Manta Queen 3 is generally regarded as one of the more comfortable and better-balanced boats, offering reasonable space both above and below deck.
Diving & Itineraries
Manta Queen 3 typically operates 6-day / 5-night Similan liveaboard trips, with around 18–19 dives depending on conditions and itinerary. These trips usually depart from Thaplamu Pier near Khao Lak, with transfers arranged from nearby resorts or Phuket.
Dives are generally guided, with groups organised according to experience levels where possible. Conditions in the North Andaman can vary, so this Similan liveaboard is best suited to certified divers who are comfortable with boat diving and occasional current.
Cabins & Accommodation
Cabins on Manta Queen 3 are functional and air-conditioned, designed primarily for resting between dives rather than extended indoor living. The boat offers a mix of cabin types, allowing some flexibility depending on budget and availability.
En-suite cabins offer added privacy, while shared cabins are commonly chosen by budget-conscious divers or groups travelling together. Storage space is limited but sufficient for personal belongings during a liveaboard trip.
Onboard Facilities
The layout of Manta Queen 3 focuses on practicality. The main deck includes a shaded outdoor dining area where most meals are served, along with an indoor saloon used for briefings and relaxation.
The upper deck features an open sun deck with seating and loungers, providing space to unwind between dives or in the evenings. While facilities are modest, they are adequate for the pace of a Similan liveaboard schedule.
The dive deck is set up with individual gear stations, tank racks and entry points designed for smooth dive operations. Camera rinse areas and preparation tables are available, though photographers should expect shared space.
Food & Dining
Meals on board are served buffet-style and are generally a mix of Thai and Western dishes. Food is prepared to keep divers fuelled throughout the day, with three main meals and snacks between dives.
Tea, coffee, drinking water and soft drinks are usually available throughout the trip. Alcoholic beverages may be available for purchase, depending on the operator and trip details.
Safety & Crew
Manta Queen 3 is equipped with standard marine safety equipment and is operated by an experienced crew familiar with North Andaman routes and conditions. Dive briefings are conducted before each dive, covering site conditions, depth limits and safety procedures.
As with all Similan liveaboard trips, divers are expected to carry appropriate dive insurance and meet minimum certification requirements. Nitrox may be available on some trips for certified divers, usually at an additional cost.
Who Is This Boat Best Suited For?
This Similan liveaboard is best suited to divers who prioritise dive time and access to well-known sites over high-end accommodation. It appeals to budget-minded travellers, small groups, and divers who are comfortable with shared facilities and a straightforward onboard experience.
Those seeking luxury cabins, fine dining or a boutique atmosphere may prefer other options, but for consistent diving and practical comfort, Manta Queen 3 remains a solid mid-range choice.
