E-40 Power Catamaran

Designed around efficiency, resilience and simple operation, the E40 combines quiet electric propulsion with the flexibility of hybrid range extension for longer passages.

Easy Pace, Easy Control

Efficient twin hulls and large, slow-turning propellers provide smooth acceleration, precise manoeuvring in marinas and relaxed cruising at passage speeds.

One Screen, Total Oversight

Earthling’s E-THOS system brings propulsion, battery storage, charging, solar generation and onboard energy use together in a single helm interface, making it easier to understand and manage the boat’s energy systems.

Hybrid When It Helps

Two 8.5 kW DC generator-chargers provide additional range when required, allowing longer itineraries without relying solely on the battery bank while keeping fuel use and noise to a minimum.

Light, Strong, Efficient

Based on Alan Carwardine’s Stealth 36 powercat hull form, the E40’s slender hulls minimise drag and allow efficient cruising at 10–12 knots with relatively modest power, applying the same efficiency principles that make sailing catamarans so effective.

Proven in the real world
The E40 has been built, commissioned and extensively operated at sea, including long-distance Mediterranean cruising, and independently sea-trialled by specialist marine media.

SEE THE E40 IN FRANCE THIS SEPTEMBER
