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.  She is fitted with twin JD 4045 engines and 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.

Vanguard is in production (May 2021) at Naval Yachts in Antalya, Turkey.
