King Neptune is a 46-meter (150-foot) steel and aluminum-hulled luxury liveaboard, purpose-built in 2024 and joining the Neptune Liveaboards fleet in 2025 as its third vessel.
Designed for world-class diving expeditions across Indonesia, she accommodates up to 22 guests in 10 stylish en-suite cabins. Each cabin offers either king or twin bed configurations, with two cabins convertible into triples and two single cabins adaptable into doubles, ideal 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.
A professional crew of 20 ensures smooth operations and outstanding service throughout long-range voyages. With a range of 3,000 nautical miles, King Neptune is powered by two 600HP Yanmar engines and cruises comfortably at 10 knots. Onboard power is supported by three Cummins generators, while dive operations are facilitated by two Coltri 315 compressors and a dedicated Coltri Nitrox system.
Two 8-meter RHIB tenders with 150HP engines provide safe and efficient dive transfers. For autonomy at sea, the vessel is equipped with a watermaker producing up to 10 tons of fresh water per day, backed by a 45,000-liter freshwater tank and a 40,000-liter diesel tank, ensuring comfort and reliability even on extended expeditions.
