King Neptune

Meet King Neptune, a 46-meter (150-foot) steel and aluminum-hulled luxury liveaboard purpose-built in 2024. She joined the Neptune Liveaboards fleet in 2025 as its third vessel, designed for world-class diving expeditions across Indonesia. Up to 22 guests settle into 10 en-suite cabins, each with king or twin configurations, individually controlled air conditioning, and panoramic sea views.

Diving Nusa Penida

Based around the waters of Nusa Penida, King Neptune is built for divers who want to venture beyond the day-trip radius. Enriched air (Nitrox) is available on board, supported by two Coltri 315 compressors and a dedicated Coltri Nitrox system, so certified divers can extend their bottom time across long-range voyages. Two 8-meter RHIB tenders handle transfers to the sites.

A professional crew of 20 keeps things running smoothly, and thoughtful touches ashore and afloat — Wi-Fi, warm-water showers, a battery charging station, and Fish ID and diving books — round out life on board. English and Indonesian are spoken, making King Neptune a natural fit for international divers chasing Indonesia's underwater highlights.
