Tambora design and construction has been done from scratch around five core themes. Decisions on major design elements, or choices of equipment, material and color, have been taken bearing these themes in mind. They are at the very heart of what Tambora stands for.

  • 21st Century Luxury & Amenities- Tambora offers all luxury and amenities you can imagine. At the same time, she makes away with many shortcomings frequently encountered on a dive liveaboard. Naturally, space is at premium on a ship. Hence, Tambora has been sized and configured to comfortable accommodate a maximum of 16 divers.
  • Custom-Designed & Built for Scuba Diving- Tambora has been designed and built from scratch as a liveaboard vessel catering to the needs of divers. She offers great comfort and flair, and at the same time is optimally geared towards supporting a diving operation in terms of safety, convenience, and efficiency.
  • Old World’s Charm & Style- Tambora has been built by traditional boat builders on the island of Sulawesi, in the centuries-old tradition of a wooden Phinisi. The design and materials used guarantee immense strength and resilience of all key structural elements, especially the keel, hull and decks.
  • Lowest Possible Carbon Emmissions- Tambora’s propulsion system has been engineered for maximum fuel efficiency. At the heart is a new, genuine marine engine, which is significantly lower on fuel consumption. The fine-blade properller has been custom-designed and fabricated from a special, stiffer alloy, minimizing power losses due to both internal vibration and unnecessary slip.
  • 1st Class Safety Features- Tambora’s design and construction specifications meet or, in most instances, comfortably exceed the requirements as laid out in the construction manual for wooden sailing motor yachts by the Indonesian classification bureau, PT. Tambora carries the full range of International Marine Organization- conform safety, communication and navigation equipment.


Tambora has been sized and configured to comfortably accommodate a maximum of 16 divers. It has 8 spacious guests suites. Each suite has a large en-suite bathroom, choice of double and large twin beds (no bunk beds!), ample storage space, and a writing desk.

There is a large salon with separate dining and relaxing sections, offering enough space during mealtimes, as well as for chilling out over a chat and drinks with fellow divers. Tambora has three separate lounge decks at the bow, aft and salon rooftop. They provide enough space and privacy, and can be fully shielded from the sun.


Tambora’s chef serves a menu of tasty Indonesian, European and Japanese specialties, freshly prepared in their well-equipped kitchen. Five meals per day mean there always is a tasty bite awaiting guests when they surface!

  • Snack prior to the first dive of the day: coffee, tea, fruit juice, milk, toast, selection of biscuits
  • Breakfast after the first dive: 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: buffet-style, with a different range of Indonesian favorites every day
  • Afternoon snack after the third dive of the day: variation of cakes, fruits, and Indonesian specialties, with coffee and tea
  • Dinner: served; soup, salad and main course, alternating between European and Asian specialties
  • 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
  • Wine, of which they carry a fine selection, and liquor are charged on a separate basis
