It carries a 41 kWh battery and a 40 kW motor for a top speed of 12 knots, sleeps six across three cabins, and has a solar roof intended to extend range under way. At 2,900 kg it is exceptionally light for a ten-metre catamaran with accommodation. It won a Gussies Electric Boat Award in 2025 and the Cannes Innovation Route in 2025, and is a Motor Boat of the Year 2026 finalist.

Range is propeller-dependent: the builder confirms ~80 nm (10 h at 8 kn) with the long-range propeller in favourable summer conditions, the rooftop solar assisting — shorter with other propellers. Inboard and outboard configurations are offered. Confirmed by Philippe Raynaud (CEO) by email, 2026-08-11.
What a buyer should know
Who it suits
The M.10 Plaisance is a slow-cruising liveaboard for two couples or a family, aimed at sheltered water, coastal hops and protected marine areas where combustion boats are restricted or unwelcome. Three cabins and six berths on a 9.95 m hull is a genuinely useful amount of accommodation, and the twelve-knot ceiling tells you the intended rhythm: this boat is for going somewhere pleasant slowly, not for covering distance.
The weight is the story
Two thousand nine hundred kilograms for a ten-metre catamaran with three cabins is remarkably light — many comparable cruising cats of this length carry two or three times that. Light weight is what makes 40 kW enough and what makes the solar roof meaningful rather than decorative, since a light hull at 5 knots may draw little enough for solar generation to offset a real share of it. It is also the figure most worth verifying at survey, because it implies construction choices that a buyer should understand before committing.
Honest caveats
The 41 kWh pack against a 40 kW motor means roughly an hour at full output; this boat lives at low speed by design, and a buyer who does not accept that will be unhappy. More importantly, Millikan's own pages give conflicting range claims — over 100 nautical miles in one place and 80 nautical miles at 8 knots in another — so we have left range blank rather than pick one. Get a single written figure, with the speed and battery configuration it assumes, before you rely on it. No price is published, and the yard is only a few years old.
Written from the builder’s published specifications and the wider market, not from testing the boat ourselves. Always confirm figures with the manufacturer before committing.
