Description and details

Diving on the Mikumba Ratu Laut in Indonesia

Boat Features

Although the vessel is relatively small in size, it capitalizes on its refurbishments of modern facilities. There are 3 areas where users can chill out. Of these 3 areas, one is specifically allotted with a TV for movie watching. The top deck offers an open space for enjoying the amazing water views or for moments where you just want to enjoy the warmth of the sun.

For non-divers, there is snorkeling equipment which can be rented. Crew to guest ratio is nearly 1 guest to 1 crew, assuring that utmost assistance is extended to everyone onboard.

There is an audio-video entertainment system, charging stations,and place torinse underwater cameras.

The Cabins

A maximum of 12 guests can be accommodated in the cabins. The lower deck houses two quad cabins which are ideal for groups of friends or families, and two twin bunk bed cabins which are ideal for partners or buddies.

Each quad cabin can accommodate a maximum of 4 persons. The twin bunk bed cabins on the other hand can accommodate a maximum of 2 persons. Both types of cabins offer the convenient use of air condition and private bathrooms. All rooms are deemed non-smoking rooms.

Food & Beverage

Al fresco dining is offered by RatuLaut to where guests can feast on various dishes of Western and local origins served in buffet style. There are both vegan and vegetarian options,so whichever is preferred can also be served. Guests with specific dietary requirements can also make advanced notices prior to boarding. In between dives, snacks are usually served to give the guests the chance to refuel before again embarking on an energy-draining but refreshing dive.

Aside from regular beverages like water, coffee, and juices, guests can also enjoy some bottles of fresh beer, best enjoyed while having friendly conversations.


Because the vessel cruises in coordination with Barefoot Conservation, guests will not only have chances to explore the waters to take interesting underwater shots to exercise their underwater photography skills. They will also get to have some experiences working and diving along expert marine scientists who take dives to study, analyze, and interpret marine animals and their natural ecosystem. There are also land excursions dependent on the chosen routes.


Since its initial cruise in 2008, the vessel never fails to take guests on amazing trips and dives on the dedicated route of Raja Ampat. The cruise usually lasts for 6 nights. During the cruise, guests are offered the opportunity of meeting up close schools of fishes, turtles, mantas, tuna,and even rare wobbegongs. A maximum of 4 dives can be enjoyed per day where various corals, anemones, and sponges can be seen.

When to Go

Sailing through Raja Ampat is best enjoyed on the months of October until the end days of April. Although there are still cruises on other months, strong winds and currents should be expected. Such instances may be regarded by some sailors and divers both as challenging and adventurous.
