Anyone looking for the best diving boat at Indonesia’s should certainly consider KM Raja Manta. This purpose-built liveaboard ship was designed by divers, for divers, and it was first launched in 2011. At 36m in length and 7.5m wide, Raja Manta is one of the largest, and therefore most stable, Indonesian liveaboards. 

Raja Manta offers its guests unbeatable comfort & luxury at competitive prices. The trips are extremely well organized, making sure that nothing is forgotten or goes wrong. The air-conditioned cabins and communal areas are clean, large & well furnished. Divers enjoy excellent equipment & facilities, making entries exits effortless & safe. The amenities and service-minded staff make it difficult to leave at the end of the trip and many guests book to come back again.

Raja Manta started its life known as White Manta, and quickly built an excellent reputation for great service, comfort & safety. Until recently, the boat alternated between Thailand's Similan Islands, and Indonesia. But it now stays in Indonesia all year round, and offers cruises at the best locations for each month. Unlike many other Indonesia diving liveaboards which are based in one area and unable to travel great distances or use other ports, Raja Manta is very capable. The boat spends the high season in Raja Ampat, then moves to the eastern side of Borneo for the high season there. In between, there are 'crossing trips' which visit some amazing locations on the way. Wherever Raja Manta is, wonderful diving is guaranteed.

Raja manta SundeckDue to the distances to cover between the islands, it’s important to sail on a large and comfortable boat. Raja Manta makes the journeys easily, ensuring comfort and luxury for everyone on board. Once at the islands, the diving and beach excursions are made easy thanks to two support dinghies fitted with 40hp motors.

The boat's cabins are on three decks. The uppoermost deck is where two double-bed cabins are, but these can also be converted into side-by-side twins. At the front of the main deck are two more double cabins. Also on the main deck are four cabins which have 2 or more single beds, but are normally only sold to two guests, unless a group of three really want to share. All of the cabins on the main and upper decks have private bathrooms, sea-view windows, and plenty of space to store luggage and personal items. On the boat's lower deck are three more cabins that have bunk beds and normally take no more than two guests. These cabins have wash basins inside, and share showers and toilets on the same deck, that are not available for other guests or staff to use. All of Raja Manta's cabins are air conditioned, and have plenty of electrical sockets and storage space. Guests who come alone are normally only placed with another guest of the same gender.

The communal areas include a large air-conditioned lounge saloon that has audio-video facilities. However, most guests spend their time aboard socialising or relaxing in the huge covered outdoor dining area which has plenty of space and five large tables. There is also a large sundeck on the top of the boat, where guests can sunbathe, read a book, or just gaze at the stars at night.
