Conquer the Wild Oceans: 144-Foot Expedition Yacht "Sharkwater" - Yours for $1,495,000
Unleash your inner explorer with "Sharkwater," a rugged, research-vessel-turned-luxury-expedition yacht, built to military-grade standards and boasting a 7,600 nautical mile range!
If you love converted vessels, then you will probably love this fantastic boat. Sharkwater is a 144-foot steel-built explorer yacht constructed in 1997 as a Japanese research vessel. Designed and built to military standards by Niigata, she has since been converted into a dive and research yacht, capable of handling very remote waters with the sort of reliability that any off-grid owner needs. Her potent design and engineering make her well-suited for a variety of challenging conditions, from polar waters to tropical expeditions. This is the sort of vessel that can head out to sea when most other boats are searching for calmer waters. She is currently listed for sale with Fraser Yachts at $1,495,000, offering a serious expedition-ready platform at a competitive price.
Built for Exploration
Sharkwater is designed and built for serious durability. With a steel hull and superstructure, she was constructed to operate in most weather conditions. Her engineering prioritises reliability and efficiency with ease of day-to-day maintenance, resulting in lower operating costs compared to similar-sized explorers. Her solid construction helps ensure long-term usability, with minimal maintenance requirements compared to other explorer yachts, which prioritise aesthetics over functionality.
Her Niigata 6MG25HX main engine, paired with a variable pitch propeller, offers 1st class fuel efficiency, allowing her to cruise at 10 knots with a maximum speed of 13 knots. With an impressive range of 7,600 nautical miles, she is suited for long-distance adventures. Whether navigating coastal waters or embarking on transoceanic journeys, she provides steady and reliable performance. Her fuel consumption, again, when compared to vessels of a similar size, remains manageable even on extended trips, making her an economical option for those planning lengthy adventures.
A Diver’s Platform
Sharkwater is equipped with two L&W 320 EMC dive compressors for diving operations and has space for additional equipment if needed. A 5-ton davit crane and a large deck allow for the storage of multiple tenders, making dive operations straightforward. Her spacious dive deck offers ample room for divers to prepare, store their gear, and access the water with ease.
The aft deck is spacious and covered, providing a practical area for dive preparations and relaxation. This space could also be enclosed for controlled storage or other applications. The boat deck, originally designed as a helicopter landing pad, could be reinstated if required. This feature is particularly useful for research teams, expedition crews, or private owners who want the flexibility of aerial access; heli skiing, anyone? Additionally, the onboard equipment makes her well suited for scientific missions, underwater archaeology, or conservation efforts.
Functional Accommodations
Sharkwater accommodates up to 12 guests across five cabins, each with ensuite heads. The master cabin is located on the pilothouse deck, while the remaining cabins are on the main deck. The main salon features a large TV, a dining area for 10, and a wet bar. The guest accommodations are comfortable yet practical, designed to support long-term stays without unnecessary extravagance.
The bridge deck includes a sun lounge and a forward viewing area, providing wide views. A commercial-grade galley supports catering needs for extended trips. With ample cold storage and efficient use of space, the galley can sustain guests and crew for weeks at a time.
The crew quarters are thoughtfully designed to balance comfort and efficiency, ensuring a well-rested and capable team even during extended missions in remote waters with prolonged periods at sea. With smart space utilisation, ample storage, and easy access to operational areas, the layout allows the crew to perform their duties seamlessly while maintaining a practical living environment
Explorer Capabilities
Sharkwater is designed for self-sufficient operations. With 92,364 litres (24,400 US gallons) of fuel capacity and two water makers producing an impressive 1,200 gallons per day, she can remain at sea for long periods. Her systems include a hydraulic steering system, commercial-grade fuel and oil transfer setups, and an extensive firefighting system. The vessel’s electrical and mechanical systems are designed for ease of maintenance and reliability, reducing the risk of downtime during critical operations.
Her full navigation suite and extensive communication systems provide enhanced situational awareness and connectivity, including Furuno sonar and radar, Tokimec gyrocompass, and Starlink marine antennas. Whether conducting remote research or supporting an off-grid charter, these systems ensure seamless operations.
Ready for Use
Currently in Cancun, Mexico, Sharkwater is available for exploration. Whether for diving, research, or long-range travel, she offers a capable platform. Her combination of efficiency, durability, and versatility makes her an appealing choice for a range of users, from private owners to expedition teams and research groups.
For anyone looking to own a reliable and practical explorer yacht, Sharkwater presents a unique opportunity. Her conversion from a research vessel ensures that she is built to withstand harsh conditions while still offering comfort for extended stays. She is currently listed for sale with Fraser Yachts.
