King Neptune is a 46-meter (150-foot) steel and aluminum-hulled luxury liveaboard yacht, purpose-built in 2024 and set to join the Neptune Global fleet as its third vessel in 2025. Designed for exceptional diving expeditions across Indonesia, the vessel accommodates up to 22 guests in 10 en-suite cabins, each offering king or twin bed configurations. Two cabins can be converted into triples, and two single cabins can be transformed into doubles—perfect for group leaders or dive professionals. All cabins are located on the main or upper deck, featuring en-suite bathrooms, individually controlled air conditioning, and panoramic sea views for a comfortable and immersive onboard experience.

King Neptune is crewed by a professional team of 20 and is equipped for extended voyages, boasting a range of 3,000 nautical miles. Powered by two 600HP Yanmar engines and cruising at a service speed of 10 knots, the vessel ensures smooth and stable journeys. Its three Cummins generators provide reliable onboard power, while two Coltri 315 compressors and a dedicated Coltri Nitrox system support advanced dive operations.

Supporting its diving program are two 8-meter RHIB tenders powered by 200HP engines, ideal for safe and efficient dive transfers. The vessel also features a watermaker system capable of producing 10 tons of fresh water per day, supported by a 45,000-litre freshwater tank and a 30,000-litre diesel tank to sustain long-range expeditions.

King Neptune combines thoughtful comfort, technical reliability, and spacious design to deliver unforgettable diving adventures across the Indonesian archipelago.
