Dewi Nusantara is renowned for operating in some of the planet’s most diverse and exciting dive destinations. With more species of coral and marine life than anywhere else on earth, the seas of the Indonesian archipelago lead the world when it comes to marine life biodiversity. Our itineraries visit some of the country’s most spectacular areas.

Depending on your trip itinerary, you will visit Ambon, Alor, Banda Sea, Cenderawasih Bay, Triton Bay, Forgotten Islands, Halmahera or Raja Ampat in Papua. You will be making up to four dives a day in some of the most sought-after dive destinations on the planet.

Site selection depends on many variables, such as weather and sea conditions but also on you – tell us what you would like to see and do, and we will do our very best to accommodate your wishes.

On Dewi Nusantara everyone is a VIP!!

All diving from Dewi Nusantara is carried out using our custom-built tenders. The diving at some of the sites in some areas is considered relatively advanced because of the strong currents which can be encountered there – but don’t worry; we won’t put you into any hazardous situations. You will be responsible during your trip for planning your dive profiles. In doing so, we ask that you adhere to the standard safe diving practices set forth by your training agencies. Detailed briefings will be given before every dive.

The core team get help from four local dive masters for guiding; without exception, all are very experienced in the areas we dive. There will be a detailed briefing on the first day of the cruise regarding general dive procedures, safety issues, photography, and marine life awareness concerns.

Directly preceding every dive, a full dive briefing is given with information concerning dive type, suggested depths and marine life expectations, amongst other things. Hand-drawn site maps will be used for these briefings. Groups never consist of more than four to five divers per dive guide. A private dive guide is possible on request (subject to availability) and at extra costs. You’ll need to book a private dive guide at least three months before your planned cruise.

While we are sure our guests’ scuba equipment will be in good order, the equipment can sometimes malfunction after the annual service (funnily enough). Don’t worry; this will not spoil your dive trip since plenty of rental equipment is onboard to keep you in the water and diving.

Scubapro is our main scuba rental equipment brand. You can rent either complete sets or BCD, regulators, wetsuits etc. separately. We also have underwater lights and other peripheral and safety equipment for rent or sale.

Dewi Nusantara uses 12 litre (80’s) aluminum cylinders. These are designated for

use with either air or Nitrox 32. In addition, we have a limited supply of larger 15 litre (100’s) and smaller 10 litre (63’s) cylinders should you wish to use smaller or larger units. All cylinders are fitted with DIN adaptable valves. Please note there is a surcharge for Nitrox on our cruises.

All our dives are done from the two dive tenders. They were designed and built to our specifications in 2019 and offer lots of space to gear up. The 200hp, silent four-stroke outboard engine gets you from the ship to each dive site in a few minutes. You will have your own spot in the tender, with a semi-dry compartment directly below your seat.

Dewi Nusantara has excellent onboard facilities for underwater photographers and videographers. There is a very spacious dedicated camera and equipment room on the main deck with multiple charging stations, camera benches with dedicated towels, and storage space for camera gear. The lounge has a DVD player and TV for photo/video playback.

We have purpose-built wash-down tanks on the main dive deck. The tank on the starboard side is for camera and computer wash only, and the tank on the port side is used for general equipment wash down.

Once your camera is ready for the next dive, please place it in a dedicated area in front of the camera room. Our crew will transport your camera to the dive tenders. During the after-dinner briefing, our cruise director will inform you about the next day’s plans, including macro- or wide-angle setup opportunities.

 At the end of each diving day, your scuba units will be taken from the tenders and stored safely on board the main vessel in special slots. Your equipment is accessible at any time.

During your trip, we may be shooting a movie about your cruise. What is filmed underwater, on deck, and on land during the cruise is edited into an entertaining format and placed inside our stock files.

The electricity supply on Dewi Nusantara is 220-volts, with transformers available for 110-volt equipment.

Dewi Nusantara uses a Nitrox Technologies membrane system to produce our diving gases. This method is very safe and accurate. We have several O2 analysers onboard for guest use: All Nitrox fills must be analysed by the diver using it and logged before every dive. Instruction on how to analyse and log a mix accurately is available.

Please remember that you are responsible for your dive profile at all times.

Nitrox training and certification may be available onboard to all certified open-water divers for an additional charge. If you would like to change to Nitrox, please let our office know four weeks before your scheduled departure date.

Dive Safety Equipment

Guests are required to carry an SMB (surface marker buoy). We have a range of safety equipment for rental and purchase; however, we recommend bringing your own to your cruise. As part of Dewi Nusantara’s safety protocol, we give each diver a Nautilus Marine Rescue GPS locator for your use during the cruise, an SMB and a whistle. Guests will be shown how to operate this equipment correctly during the dive procedures briefing at the beginning of each cruise. We do not require guests to carry a mini strobe or a dive alert.

Oxygen Units & First Aid

Qualified guests will be shown the location of Dewi Nusantara’s First Aid Kit and the O2 units.

Fire safety

Our crew will conduct a detailed safety briefing on the first day of each cruise. It includes information such as the locations and use of life jackets, fire fighting equipment, and onboard rules regarding the charging of electrical equipment such as dive lights and camera battery packs.

If there are guests onboard who have training in either First Aid and/or O2 administration, they are encouraged to identify themselves to our cruise director and to act accordingly in the event of an emergency, and in case there would be no dive crew immediately available.

Emergency Evacuation & Re-compression Info

Please be aware you will sometimes be diving in some very remote locations. The nearest working re-compression chamber to Dewi Nusantara’s general operating areas is in Manado at the public hospital. Reaching it will sometimes require the use of emergency air evacuation, which is not always available. Please plan and execute your dives carefully.

Enriched Air Diver

This popular course consists of complete academic instruction about the principles of partial pressures within breathing gases and their effects on the body, open book tests and exam as well as a practical demonstration of gas analysis and compressor/Nitrox generation systems. The Enriched Air Diver course is usually available during a cruise.

If you would like to change to Nitrox, please inform our office four weeks before your scheduled departure date.

With the exception of Enriched Air Diver courses, Dewi Nusantara typically does not offer onboard diving instruction. If you wish to inquire about dive courses, don’t hesitate to contact us.
