Expedition Yacht Vanguard: Arctic-Proven XPM 78
The Vanguard is an XPM 78 expedition platform yacht engineered for extended, self-sufficient cruising. Built with an emphasis on fuel efficiency and systems integration, she recently completed a 7,000-nautical-mile passage along the U.S. Atlantic seaboard and into Greenland’s High Arctic, conducted with two ice pilots aboard to manage high-latitude transit and validate operational systems in demanding conditions.
The hull form and onboard systems are arranged to support long-term voyaging with minimal upkeep. Interior and exterior spaces are functional for both living aboard and mission-focused activity, making the yacht suitable for owners who plan extended passages, remote-area exploration, and frequent use in mixed coastal and offshore environments.
Diesel-Electric Praxis Hybrid Propulsion and Range
Vanguard is powered by a diesel-electric Praxis hybrid propulsion system tied into an integrated energy management network. The arrangement provides operational flexibility: efficient cruising at low shaft RPM, optimized generator loading, and the ability to allocate electrical power where needed for hotel loads, systems, and propulsion.
Reported cruise performance is 9 knots at a consumption rate of about 3.5 liters per nautical mile, yielding a practical range in excess of 7,000 nautical miles. The hybrid architecture also supports quieter operation and refined power management on long passages, with redundancy and control logic that aid fuel efficiency and system resilience.
Ice-Reinforced Hull, Stabilizers and Expedition Systems
The hull is ice-reinforced for high-latitude work and paired with DMS Magnus Master stabilizers to improve seakeeping underway and at anchor. A commercial-grade dynamic positioning system is installed to hold position precisely for tender operations, scientific work, or delicate maneuvering in constrained anchorages and fjords.
Operational fittings reflect expedition priorities: a stern deck configured for tender and gear handling, robust crane capacity and ample storage, plus low-maintenance exterior finishes. The arrangement of deck spaces, flybridge helm and access to the swim platform supports efficient crew operations and rapid transitions between transit, on-deck work, and guest use.
Arctic-Validated, Integrated Systems and Recent Upgrades
The interior by Arista Marine follows an open-plan layout with galley, helm and salon on the main deck to keep daily living and underway operations together. Finishes are restrained—pale timbers with darker contrast elements—and the helm features dual high-back chairs and a multi-display dashboard. Accommodation comprises three en-suite staterooms for six guests, a convertible salon to sleep two additional guests, and a full-beam owner’s cabin with king berth and lounge seating.
The recent Arctic passage served as a systems validation run and Vanguard has received targeted updates to maintain expedition readiness; these have focused on systems integration, navigation and sensor calibration, and routine service to propulsion and auxiliary systems. For prospective buyers or agents seeking full technical logs, upgrade records and a complete specification, please inquire for the detailed package and service history.
