This 44.7-meter Astilleros Custom Expedition Yacht is now available for sale in Genoa, Italy, representing a rare opportunity to acquire a genuine long-range explorer vessel with global cruising capability. Originally built in 1977 and extensively rebuilt in the Netherlands during a major 2007 refit, this remarkable yacht combines proven ocean-going pedigree with modern systems, upgraded engineering, and exceptional autonomy. Designed for transoceanic voyages, expedition cruising, luxury charter operations, and remote-region exploration, this vessel delivers an outstanding combination of range, capability, onboard volume, and operational flexibility.

General Specifications

Built by Astilleros and extensively modernized through a comprehensive rebuild program, the yacht measures approximately 44.7 meters in overall length, with a beam of 7.16 meters and a draft of 2.80 meters. Displacement is approximately 340,000 kilograms, reflecting the vessel's substantial construction and expedition-grade capabilities.

The yacht features a steel hull combined with an aluminum superstructure, a proven configuration widely respected within the explorer yacht sector for strength, durability, and global cruising reliability. Following the extensive 2007 rebuild, the vessel was upgraded to modern yacht standards and certified for unrestricted navigation.

The displacement hull has been specifically optimized for long-distance efficiency, smooth ocean passage-making, and superior comfort in challenging sea conditions. Her robust structure and expedition-oriented design make her particularly suitable for extended cruising programs far beyond conventional yachting destinations.

Performance & Engineering

Propulsion is provided by twin MTU 8V4000 M60R diesel engines delivering a combined output of approximately 1,860 horsepower. With more than 11,000 operating hours, these engines demonstrate proven long-range reliability and a history of professional maintenance.

The yacht has been engineered for efficient expedition cruising rather than high-speed performance. Cruising speed is approximately 12 knots, while maximum speed reaches approximately 14 knots. Fuel consumption at cruising speed is approximately 150 liters per hour, supporting an impressive cruising range of up to 3,500 nautical miles.

Twin direct-drive propulsion systems with heavy-duty five-blade bronze propellers provide reliable thrust and mechanical simplicity, making the yacht highly suitable for global operations.

Auxiliary power is supplied by three generators consisting of two 64kW units and one 36kW generator, ensuring dependable electrical supply across all onboard systems.

Accommodation & Interior Features

The yacht offers accommodation for up to 20 guests across five spacious guest cabins and six bathrooms. Additional crew accommodation includes four dedicated crew cabins and four crew bathrooms, supporting professional operation during long-range voyages and charter programs.

The interior arrangement has been designed to prioritize functionality, comfort, and operational efficiency during extended periods at sea. Guest spaces include a comfortable main salon, dedicated office area, entertainment zones, and practical circulation throughout the vessel.

The galley is equipped for long-term autonomous operation and includes professional-grade appliances such as ovens, microwave systems, refrigerators, freezers, dishwashing equipment, and extensive storage facilities.

Following the major rebuild, interior spaces were modernized to support both luxury expedition cruising and commercial charter operations.

Exterior Areas & Expedition Facilities

The exterior deck arrangement is one of the yacht's defining features. A substantial 79-square-meter bridge deck aft area provides exceptional space for expedition equipment, oversized tenders, scientific equipment, or recreational gear.

The yacht includes a forward garage capable of housing jet skis, additional tenders, and support craft. A hydraulic swim platform and hydraulic gangway enhance guest access to the water, while a 2,500-kilogram crane dramatically expands operational capability.

These features make the vessel particularly attractive for:

• Global exploration programs
• Diving expeditions
• Research operations
• Adventure charter operations
• Remote destination cruising
• Long-term liveaboard programs

Navigation & Technology

The yacht is comprehensively equipped for worldwide navigation. Electronics and navigation systems include Furuno radar systems, upgraded Simrad radar installed in 2025, B&G Hydra instrumentation, Furuno GPS systems, Sperry Marine autopilot, AIS, TimeZero navigation software, and multiple chart plotting stations.

Communication systems include VHF radios, SSB communications, Starlink internet connectivity, distributed deck routers, and onboard computer systems supporting vessel operations and navigation management.

The dedicated navigation center provides centralized control for route planning, monitoring, safety management, and long-distance operational oversight.

Luxury & Comfort

While expedition capability remains central to the yacht's design, significant attention has been devoted to guest comfort. Climate control is supported by three powerful air-conditioning compressors producing approximately 75,000 BTU each, ensuring comfortable onboard temperatures across a wide range of operating regions.

Additional comfort features include heating systems, hot water systems, entertainment equipment, televisions, DVD and CD systems, Wi-Fi connectivity, integrated audio systems, and a dedicated gym area located on the upper deck.

Underwater LED lighting further enhances the vessel's evening ambiance and visual appeal while at anchor.

Maintenance & Upgrades

A comprehensive rebuild completed at Balk Shipyards in the Netherlands during 2007 transformed the vessel into a modern expedition yacht while preserving the integrity of the original platform. Since that time, the yacht has benefited from continuous professional management, servicing, and upgrades.

Recent maintenance and upgrade works include:

• 2025 radar system upgrades
• 2025 anchor winch rebuild
• Regular antifouling programs
• Generator servicing
