Dewi Nusantara

The best way to dive Raja Ampat!

The majestic Dewi Nusantara offers outstanding style, comfort and unforgettable diving itineraries around the Raja Ampat archipelago, Banda Sea and the Komodo National Park.

The magnificent Dewi Nusantara is a three masted wooden motor boat with a design that takes you back to the classic sailing days. To set Dewi apart from all other boats operating around Indonesian waters is the design based on inspirations from stylish European and American vessels of that elegant sailing period. A trip aboard will give you the opportunity to extensively experience and explore some of Indonesia’s premier dive locations inside the internationally known “Coral Triangle” area.

Dewi’s air conditioned cabins are all individually designed and adapted for either twin or double use, all fitted with its own elegant en-suite bathroom, reading lights, desk and chair, 220V power points and clothing storage. The master suite is ideal for a special occasion with a double bed and sumptuous furnishings, a jacuzzi bath and 180 degree views over the ocean from the rear of the boat.

The friendly and experienced crew members that originally come from all over Indonesia are always up for a laugh and happy to assist with your every need, whether it is a game of chess, an ice cold drink on the sundeck or to get you into a tender for a magnificent dive. The main deck houses most of the Dewi’s facilities including a huge dive deck and a large indoor camera room with a work bench of 8 meters long with individual power outlets and spotlights under the castle deck. Perfect for the keen underwater photographer and videographer. The boat is also equipped with Nitrox facilities and will be offering rebreather diving in the near future.

The meals prepared aboard consist of an international mix with a local flair. The chefs and kitchen crew are always happy to accommodate any special dietary requirements when informed in advance. Certain special dietary and beverage requests may not be available on a consistent basis due to the remote nature of the trip location.

The Ultimate Diving team will offer you the best flight connections at the time of booking at an additional cost

Route Options

Starting and finishing at Manokwari, our 11-night Cenderawasih Bay cruises offer nine and a half days of spectacular and varied diving, with between two and four dives per day and many fascinating land excursions along the way.

The diverse underwater and stunning topside worlds of Indonesia have combined to produce yet another wonderful destination, with something very special for every adventurous diver and intrepid traveller the world over. Let Dewi Nusantara be your luxury home away from home in this beautifully unique part of the world.

Like the graceful manta ray, whalesharks are great favourites with divers and just seem to glide though the water, without a care in the world, feeding on microscopic plankton and other small organisms while all you have to do is keep up with them for a photo or video scene. Now we present a whaleshark encounter like no other, the Cenderawasih Bay Big Boys an awe-inspiring and humbling experience.

Fortunately for us and more so for the whalesharks, the local fishermen took their presence as a good luck omen and in time struck up a relationship with them, to the point where they can now hand feed the sharks the same as you would a cow.

The Cenderawasih National Park - covering 14,000 square kilometres and Indonesia’s largest, is half as much again bigger than that of Raja Ampat and has some splendid diving, even without the Indonesian Throughflows’ natural currents.

The World War Two remains of the US Navy and Japanese invaders conflict over Papua New Guinea left some extravagant wrecks and reefs.

Due to its inverted architecture, the Cenderawasih reefscape is one of the few places in the world where it is possible to observe and photograph marine species that normally live in far deeper water.

In the Arfak Reserve, it is reckoned that 320 bird species have been recorded, with around 50% of these endemic to the region.

Facing north out into the vast Pacific Ocean, Cenderawasih Bay has features that are rare, even when taking into consideration the incredible range and diversity of diving in other parts of Indonesia. In contrast to many of the other Indonesian dive centres of excellence, Cenderawasih is the only one not to be greatly affected by what is known as the “Indonesian Throughflow”.

10 nights aboard the Dewi Nusantara

We have been very happy with the service we have received from Marcelina at Ultimate Diving for our diving holidays at Layang Layang (2013) and Raja Ampat (2015). The latter especially was not easy to arrange, flights were cancelled and changed and her suggestion of overnight in Manado worked very well. We will certainly use Ultimate Diving again.
