Thalassa Liveaboard

Uncharted Cruises — KLM Thalassa 42 (Private Charter, 6–8 Guests)

KLM Thalassa 42 is a newly built (2023–24) two-mast Phinisi crafted in Bulukumba by Bugis shipwrights. Hosting 6–8 guests in 3 ensuite cabins, she’s purpose-built for exploratory routes across Indonesia — Banda & the Forgotten Islands, Halmahera, Raja Ampat, East Flores & Alor. A solarbattery system keeps nights quiet at anchor; a Nitrox membrane, high-end rental gear, two tenders, SUPs/kayaks, and Starlink (when in range) complete a small-group, go-anywhere setup — ideal for private charters focused on adventure, comfort, and time in nature.

Dive Overview

Whether you seek macro critters, large marine animals, vibrant corals, or exhilarating drift dives, Indonesia offers it all.
