Overview
The E-40 Power Catamaran is like 'sailing without sails' — a 12-metre electric powercat built for quiet passages, easy marina handling, and practical hybrid range. Twin 50 kW electric drives, a refined Stealth-lineage platform of around 3.5–3.6 tonnes, and automated energy management make 10–12-knot cruising feel unhurried. Compact DC generator-chargers sustain speed on extended passages without depleting the battery bank, while a 2 kW rooftop solar array continuously replenishes charge in sunlight.
What sets it apart
This boat is all about sustainability and resilience at sea, with energy efficiency central to achieving both. It represents an eminently practical fusion of pure electric and hybrid technologies.
Easy Pace, Easy Control
Efficient twin hulls and large, slow-turning props give smooth acceleration, precise manoeuvring in marinas, and a calm ride at passage speeds.
One Screen, Total Oversight
E-THOS, a customised intelligent system, integrates propulsion, storage, charging, solar, and hotel loads into a single helm interface, making planning and energy decisions intuitive.
Hybrid When It Helps
Two 8.5 kW DC genverters hold 10 knots without depleting charge, extending itineraries while keeping sound and fuel use low.
Light, Strong, Efficient
Based on Alan Carwardine's Stealth 36 powercat hull form, the E-40's slender hulls minimise drag and enable efficient cruising at 10–12 knots with modest power — the same principle that makes sailing catamarans fast.
