Two Molabo ISCAD V50 motors, 48 VDC, 100 kW combined. Four WhisperPower prismatic LiFePO4 modules. 9 knots draws 12 kW, 16 knots draws 50 kW. Two 8 kW genverters and 2 kW of solar (4 kW optional) extend the range. Range is speed-dependent: 40 nm at 8 knots, 28 nm at 10 knots, at 90% depth of discharge — figures from the builder, August 2026. Builder's 2026 brochure.
What a buyer should know
Light, shallow and quiet
The Earthling E-40 Power Catamaran's trick is weight. Four tonnes on a 12 m platform is remarkably light for a power catamaran, which is why twin 50 kW drives are enough for a 10–12 knot cruise; a conventional cat of this length would need several times the power. A 0.70 m draft opens up lagoons and thin-water anchorages, and the 2 kW solar array, also feeding water heating, points at the real proposition: silent, low-consumption cruising with meaningful autonomy at anchor.
Be clear about what it is
John McGettigan at Earthling gave us the battery capacity directly on 2026-07-30: 44 kWh, published at the back of the yard’s own 2026 brochure. An electric-only range at a stated cruising speed is still not published, and on a 12 m catamaran that is the figure that decides a passage. For a boat sold on the strength of long passages, that is the figure that matters most, and its absence should be the first item on your list of questions. The availability of compact DC generators as range extenders gives the honest answer in outline: this is a hybrid, not a pure-electric passagemaker.
The delivery-voyage story also deserves scrutiny. Published accounts indicate the E-40 travelled from New Zealand to Italy as cargo, with its own passage being the Mediterranean leg to Barcelona — impressive, but not an ocean crossing under its own power.
At €495,000 for 12 m with modest accommodation, this costs well above a comparable diesel powercat. You are buying silence and solar autonomy, and should want them badly.
