The Yacht

Built Specifically for the Indonesian Dive Expedition

The Seven Seas was commissioned with a specific purpose: to take serious divers to the places that most charter yachts cannot or will not go. Launched in 2011 as a 40-meter phinisi custom-designed for extended Indonesian cruising, she has spent fifteen years doing exactly that. Raja Ampat. Komodo. The Banda Sea. The Forgotten Islands.

Her hull follows classic phinisi design: a deep, seaworthy keel and twin masts rigged with seven sails for authentic passages when the trade winds cooperate. She is built from ironwood with teak decking and interior joinery throughout, sized and rigged for the long ocean passages that define eastern Indonesian exploration rather than for short coastal hops.

Three decks accommodate 14 guests in eight air-conditioned en-suite cabins. Wide shaded deck areas and practical interior spaces are arranged for the daily rhythm of a liveaboard, from the dive deck at the stern to the sundeck aloft. The galley draws from Indonesian specialties, fresh local produce, and freshly-caught seafood, with the variety that extended itineraries demand.

The dive operation is the heart of the boat. Multiple compressors, a fully equipped dive shop, and three 6.5-meter twin-engine dive tenders give the team the range to reach sites inaccessible to yachts relying on a single tender. Up to four dives per day are standard, and the lead guides have worked alongside leading conservationists and underwater photographers in these waters.

What The Seven Seas offers is not the largest deck or the newest interior. It is the combination of genuine expedition capability and a crew that has done this long enough to know the dive sites that never appear on a published itinerary. For divers who have already checked off the well-known sites, that distinction matters.

The Experience

A Day Aboard The Seven Seas

The day begins before sunrise. The dive team briefs guests over coffee while the anchor chain comes up, and by first light the tenders are in the water heading for the morning's site. Water temperature in Raja Ampat sits around 28 degrees Celsius; visibility at the better sites runs to 40 meters on a good day. The expedition leader is already in the water by the time guests arrive at the entry point. Between dives, guests return to find the cook's buffet set out on deck, the smell of fresh ginger and coconut rice drifting from the galley.

Afternoons move at whatever pace the group sets. Non-divers take the kayaks into mangrove channels or ride a tender to an isolated beach while divers complete their third descent. As the light falls, guests gather on the sundeck with the satisfaction of people who have spent the day doing what they came to do. Dinner follows the sunset, and the conversation tends toward the next day's plan.

Technical Specifications

Expedition Leaders

The Seven Seas carries expedition leaders on every charter, not as a luxury add-on but as a core operational component. Their role combines dive guiding, marine biology interpretation, and logistical expertise built across years of working the boat's eastern Indonesian routes.

Accommodation

Eight Cabins, Three Decks

The eight en-suite cabins are distributed across three decks in four double and four twin configurations, all air-conditioned and finished in warm teak with Indonesian textiles. The doubles take king beds; the twins are sized for large singles. Two of the doubles sit on the upper deck with views of the day's anchorage. The arrangement suits both mixed groups and dedicated dive parties, with flexibility in how cabins are assigned.

The main lounge and dining room occupy the central deck, with the galley adjacent. Teak furniture throughout, multiple shaded lounging areas on the upper deck, and a sundeck aloft give guests room to separate or congregate as the mood shifts. The bow platform, rigged for safety from the bowsprit, is where guests position themselves during passages when dolphins work the bow wave.
