Additional Specifications and Features of XPM78-02 “Vanguard”

Hull and Design

Vanguard is constructed from aluminium and features an ice-strengthened hull built to withstand high-latitude cruising conditions. Her hull design incorporates a box keel, twin rudders, and a shallow 1.3m draft, allowing her to dry out upright and access remote anchorages. Generous bulwarks forward enhance safety and reduce green water over the deck in heavy weather. Portholes along the hull sides offer natural light and views during long-distance voyages.

Propulsion and Power Systems

Vanguard is fitted with a twin-engine configuration using John Deere 4045 AFM85 M1 engines, each delivering 160hp (M1-rated for continuous operation). These engines are globally supported, known for their reliability, and backed by a wide service network. The dual-engine layout provides full propulsion redundancy—each engine has independent systems and can operate the vessel on its own.

The vessel also incorporates a parallel hybrid propulsion system supplied by Praxis Automation. Two 30kW DC electric motors, connected via an electro-mechanical clutch, allow for silent operation when desired. Propulsion can be switched seamlessly between diesel, electric, or hybrid mode, depending on operational needs.

Energy Efficiency and Solar Power

The deck features 36 square metres of solar panels, delivering up to 6.3kW per hour in peak conditions. This contributes around 38kWh per day in optimal sun exposure, which is sufficient to meet house loads and charge the 120kWh lithium-ion battery bank. While the solar array does not power the HVAC system directly, it reduces generator reliance and supports sustainable operation.

Interior Configuration

The interior includes three en-suite cabins: a full-beam master suite, a VIP double cabin, and a twin guest cabin. The main salon features an open-plan layout with the galley and interior helm station forward. The salon seating area can convert to an additional double berth if required. The elevated saloon and flybridge deck heights offer enhanced visibility and generous headroom, improving the sense of space and comfort.

Flybridge and Exterior Living

The flybridge includes a secondary helm, dining and lounge seating, and panoramic views—perfect for navigation or relaxation. Aft, the cockpit includes an L-shaped seating area with a barbecue, refrigerator, and sink, designed for alfresco dining and extended liveaboard use. The aft deck is arranged for both function and comfort, making it ideal for long passages and remote anchorages.

Stabilisation and Handling

Vanguard is equipped with DMS MagnusMaster rotor stabilisers—an innovative system that uses the Magnus Effect to generate lift perpendicular to water flow. These retractable stabilisers provide active roll reduction both underway and at anchor. The vessel also features a Commercial Dynamic Positioning System for station-keeping without anchoring, enabled through twin rudder control and a large bow thruster.

Steering and Control Systems

Her Wills Ridley hydraulic steering system, independently actuated per rudder, allows for precise control under challenging conditions and forms part of the vessel’s triple redundancy for helm control. A selector valve ensures rudders can be synchronised easily during manual operation. The Praxis Automation MIMIC display integrates navigation, alarm monitoring, ship-wide system control, and CCTV from a single interface.

Electrical Systems

The yacht includes dual 25 kVA high-frequency power converters and isolation transformers for shore power compatibility and protection from galvanic corrosion. Vanguard has no standalone generator; instead, she utilises engine-driven power generation and batteries to provide full operational capability, including silent HVAC operation overnight on battery power.

Navigation and Electronics

Vanguard is outfitted with a Furuno navigation suite, including dual Doppler radars, AIS Class A, GPS, and a TZ Professional charting system with global coverage. She also includes a MIL-SPEC FLIR thermal imaging system, offering advanced situational awareness in low-visibility conditions.

Tender and Launch System

She carries a Highfield 5.5m RIB tender (as used by the UK Antarctic Survey) with a 100hp Yamaha outboard. Launch and recovery are managed via a FEM carbon fibre davit, and boarding is via a carbon fibre passarelle.

Certifications and Classification

• Built to MCA Category (0)

• Certified to MCA Category (2)

• CE Category A (Open Ocean)

  These designations underscore Vanguard’s capability for commercial charter, global cruising, and operations in remote or extreme environments.
