The XPM78 Vanguard is the second in a series of builds to a 78-foot design by Artnautica. Built to UK MCA Category 0 (Unrestricted) standard, she is capable of safe, long-range operation worldwide under most sea and weather conditions.
Vanguard is built to commercial standards including full redundancy of mission-critical systems. Her hull scantlings are considerably over specified to resist harsh treatment and conditions. She is self righting and designed to dry out for maintenance and repair. She is fitted with twin JD 4045 engines and Praxis hybrid electric drives backed by a large split LiFePO4 Battery bank. Power storage is sufficient for about 4 days at anchor without the need to operate diesel generators. Hybrid drives also serve as generators negating the need for a stand alone unit. All hotel electrical equipment utilizes Victron Cerbo system. Power is augmented by a 6kW solar array providing for in excess of predicted nominal daily hotel loads.
Her tender is designed for a single fuel setup, refueling diesel from the daily service tanks and to act as tug if needed. The hull is reinforced for operation in ice with a full length segregated double bottom and jet drive to minimize fouling and draft.
Navigation uses Navionics Time Zero Professional including AR augmentation. Navigation equipment and sensors are mainly Furuno to commercial standards. Navigation in ice and darkness is assisted by a Mil Spec low light and IR azimuth camera with IR illumination laser. The vessel is equipped with a Praxis DP(0) Dynamic Positioning system to enable short handed operation. All signal integration uses Ethernet CAN Bus, hardened and duplicated. Communication uses One Web Broadband, Iridium Certus, SSB and VHF Radio.
Vanguard is in production (November 2022) at Naval Yachts in Antalya, Turkey.
