WiSu — Wisdom of the Sea
Boutique Expedition Liveaboard. Designed for space, not capacity.
Explore Indonesia aboard WiSu — a 38-metre handcrafted Phinisi created for just 10 guests across five cabins, with generous space to simply enjoy life at sea.
A quieter way to explore Indonesia.
WiSu was created for travelers who value presence over pace. Small groups, thoughtful journeys, and genuine Indonesian hospitality shape every expedition — from Komodo to Raja Ampat and the remote Banda Sea.
Rather than rushing between destinations, we embrace the rhythm of the ocean itself: sunrise dives, long conversations, calm anchorages, and evenings beneath open skies.
"To dive with WiSu is to experience Indonesia not as a tourist, but as an invited guest to the ocean's most exclusive galleries."
Designed for slow days at sea
WiSu was created as a floating home for small groups seeking a calmer way to explore Indonesia. Warm wood interiors, open-air lounges, calm anchorages, shared meals and long conversations shape the rhythm on board — whether diving remote reefs, snorkeling in turquoise bays, exploring small island villages, or simply watching the horizon pass by.
Along the journey, guests experience not only extraordinary marine life, but also the warmth of Indonesian hospitality and moments of genuine connection with coastal communities across the archipelago. Every expedition is designed around comfort, presence and a deeper relationship with the ocean.
