The Boat
Premium phinisi liveaboard, built for diving in Indonesia
Built in South Sulawesi, Mari is a 30m traditional Indonesian phinisi, carrying up to 14 guests. 7 sea-view ensuite cabins sit on the main deck, while 4 deck levels give everyone room to settle into the rhythm of the trip.
Between dives, gather over Indonesian and Western meals in the 50 sqm al fresco dining area, take in the sea from the sundeck or find a quiet corner on the open sky deck.
All of this comes together as an affordable liveaboard that offers luxury where it matters: a capable dive operation, personal service and comfortable spaces. From Komodo and Sumbawa to Raja Ampat, Triton Bay and the Banda Sea, she sails Indonesia's defining dive regions.

Top liveaboard destinations in Indonesia
Sitting at the apex of the Coral Triangle, Raja Ampat brings dense coral gardens, manta cleaning stations and species found nowhere else — from walking sharks to wobbegongs. Karst islands and turquoise lagoons make the surface intervals just as compelling.
Explore Raja AmpatDive Komodo’s current-swept pinnacles, coral reefs, and manta cleaning stations on a liveaboard built around serious diving. Above water, volcanic islands, pink beaches, and Komodo dragons make the journey just as distinctive.

Banda Sea
Remote reefs, volcanic islands and seasonal hammerhead diving.
One of Southeast Asia's deepest seas, the Banda Sea is a remote liveaboard passage through volcanic islands, deep walls and historic Spice Islands. Seasonal upwellings draw schooling hammerheads, while Manuk's olive sea snakes add another singular encounter.
Explore Banda SeaOctober to March · 12 nights minimum, combined
Triton Bay
Vivid soft corals, whale shark bagans and a quieter side of West Papua.
Triton Bay is remote, richly colored and shaped by nutrient-rich water. Its soft coral gardens, wobbegong sharks and schools of sweetlips reward patient divers, while seasonal whale shark encounters at traditional bagan platforms add a rare surface-level highlight.

Sumbawa
Whale sharks, volcanic islands and the journey between Bali and Komodo.
On the quieter waters between Bali and Komodo, Sumbawa combines seasonal whale shark encounters in Teluk Saleh with healthy reefs around Moyo, volcanic scenery at Satonda and a more unhurried side of Indonesia's liveaboard corridor.

Top value for money
We took an 11 day trip to Misool and Dampier. The crew and dive guides led by Ungke were very friendly and absolutely went out of their way to find the best sites for our group's interests, from mantas to muck diving. Food was fantastic, cabins were comfortable, and the whole trip felt like incredible value for what we experienced. Would book with Mari again in a heartbeat.

Best crew ever for an amazing dive adventure
Very knowledgeable dive guides for all the different dive sites, with time for photo enthusiasts to get the shots they wanted without holding up the group. Briefings were thorough and the whole crew felt like family by the end of the trip. Highly recommend for anyone serious about their diving.

Superb Komodo Cruise
The dives were all more incredible than the last. The boat is in very good condition; nothing is missing. The crew is really attentive and clearly passionate about diving themselves, which made every briefing exciting. Meals were varied and delicious, and the itinerary hit all the highlights Komodo is famous for. Can't wait to sail with them again.
