The Class 6 Power eSolar is designed for those who dream of crossing oceans with minimal environmental impact. With up to 10kW of solar panels covering the flybridge and deck, combined with a lithium battery bank up to 100kWh, you can cruise silently for hours or even days.
The lightweight 14T displacement means less energy is needed to move efficiently. At 6-8 knots in range mode, the solar panels can often replenish what you use, making true energy-neutral passages possible.
For extended passages like Trans-Pacific crossings, the optional KiteSail systemprovides emergency propulsion using wind power, while a compact DC generatorensures you're never without reserve power.
Solar Harvest
6kW to 10kW+ of solar panels on flybridge and deck — enough to cruise at range speed indefinitely
Battery Bank
40kWh to 100kWh lithium battery bank for silent cruising and overnight hotel loads
Electric Motors
Twin 20kW to 40kW electric motors — whisper-quiet propulsion with instant torque
Energy Management System
A fully integrated solar-electric system designed for autonomous long-range cruising.
Solar Array
6kW to 10kW+ installed capacity
High-efficiency marine-grade panels integrated into the flybridge hardtop and forward deck areas. The curved surfaces are optimized for maximum sun exposure throughout the day. In tropical latitudes, expect 30-50kWh of daily harvest.
Lithium Battery Bank
40kWh to 100kWh capacity
Marine-grade LiFePO4 batteries with integrated BMS. Designed for 3000+ cycles and 10+ years of service. The lightweight lithium chemistry saves over 500kg compared to AGM, contributing to our record-breaking efficiency.
DC Generator
Optional backup power
For extended passages, an optional Fischer Panda DC generator provides reliable backup charging. Run it for 2-3 hours daily to maintain battery levels during cloudy weather or higher-speed cruising.
Energy Consumption vs Speed
The ultra-lightweight Class 6 requires significantly less power than heavier competitors. At 6 knots, consumption drops to levels that can be sustained by solar alone.
KiteSail Emergency Propulsion
For true ocean-crossing capability, the Class 6 Power eSolar can be equipped with an emergency KiteSail system. If you exhaust your battery reserves and solar isn't enough, deploy the kite to harness wind power.
The kite flies at altitude where winds are stronger and more consistent, pulling the catamaran at 4-6 knots while simultaneously regenerating your battery bank through the electric motors operating as generators.
This redundancy makes Trans-Pacific passages feasible for the adventurous owner who wants complete energy independence.

Electric Propulsion Options
Multiple configurations to match your cruising style and range requirements.
Pod Drives
2× 20kW
Compact, efficient pod drives for maximum range. Perfect for cruisers who prioritize silent operation and fuel independence.
Saildrive Electric
2× 30kW
Recommended. Balance of performance and efficiency. Excellent for coastal and inter-island cruising with occasional longer passages.
RIM 360° Pods
2× 40kW
Maximum power and maneuverability with 360-degree rotating pods. Ideal for owners who need more speed or challenging marina conditions.
Spine Concept
The patented Wave Piercing central hull with 32-layer carbon beam creates exceptional seakeeping and reduced energy consumption.
Wave Piercing Design
The central spine pierces through waves rather than riding over them, dramatically reducing hobby-horsing and improving comfort. In rough conditions, you'll feel the difference immediately.
Reduced Resistance
The spine's fine entry and wave-piercing bow reduce energy consumption, making the eSolar configuration viable. Less resistance means more range from every kilowatt-hour.
Enhanced Security
The 32-layer carbon beam provides exceptional structural integrity. Even in the event of hull damage, the spine maintains vessel integrity and buoyancy for safe passage.
Interior & Accommodation
44m² of living space on the bridge deck — a floating apartment with panoramic sea views.
The open-plan saloon flows seamlessly between galley, navigation station, and cockpit. Floor-to-ceiling windows create an airy, light-filled living space with 360° views.

Genesis
The Class 6 concept was born from a collaboration between Dan Levy and legendary offshore sailor Laurent Bourgnon. Both shared a vision: create the most efficient, seaworthy catamaran platform possible.
The eSolar variant takes this vision further — proving that long-range ocean cruising can be achieved with minimal environmental impact. The lightweight construction, efficient hull form, and integrated solar harvesting make sustainable ocean voyaging a reality.
Think Green. The eSolar represents the future of responsible ocean cruising.
