Throughout the entire vessel, separating walls have been soundproofed to insulate against noise and enhance privacy.  You'll find 3 outdoor decks, giving ample space for relaxing between dives, sunning and great views. In front of the bridge is the main sun deck, which is partially covered for protection agains those piercing tropical rays ... but you can also hang out on the aft deck or salon rooftop deck.  Of course, there's a beautiful salon with flat screen tv & surround sound, internet access and satellite telephone. All the latest technology you could ask for on a dive liveaboard.

The indoor dive prep area is a great space with lots of storage and you'll find excellent an setup for your underwater photography materials. The dive platform, located at the side of the vessel, can be used for snorkeling & swimming between dives.


You'll have a snack breakfast before the first dive then a cooked breakfast afterwards which will include choice of omelet, scrambled eggs, bacon and eggs, pancakes; also toast, marmalades, and fruits, served with coffee, tea, fruit juices, milk and soft drinks.  Lunch and evening meals are a delicious combination of international and Indonesian cuisine.  Drinks are on a help-yourself basis available in the salon: drinking water, a broad selection of local coffees, tea, milk, a range of soft drinks and beer are all included in the cruise fare.  Wines are available for an extra charge.

Raja Empat, Triton & Etna Bays & Cenderawasih Bay in Papua, unmatched in biodiversity, coral life and surface scenery
The Banda Sea & central Moluccas: Ambon, the Lease group, the Seram Laut group, and the Kei Islands, offering both big fish action and great critter sites
The islands off Borneo - Sangalaki, Derawan, Maratua, Kakaban and more - and the Celebes Sea, with mantas, schooling barraccudas, turtles, sharks, and other big pelagics
The Sulawesi coastline from Palu to Manado, with world famous Lembeh Strait and Bunaken National Park as well as many hidden and largely undived treasures
The large island of Halmahera, which thanks due its convoluted coastline and many satellite islands, islets and reefs boasts an immense variety of different marine settings.

Trips have been carefully chosen, planned and designed taking into account the crew's own experience, the seasonal and local weather patterns and a desire to offer Tambora guests great diversity, from wreck-diving adventures in the West all the way to the hidden islands and bays along the New Guinea coast in the East.
