A direct successor to the M.9 prototype, the M.10 electro-solar catamaran from Millikan Boats marks an industrial milestone in the development of clean, silent and autonomous yachting. Designed on the basis of feedback from the professional operation of the M.9, this production model focuses on the reliability of the electro-solar system, optimization of on-board living space and adaptability to family use.
Development based on over 500 nautical miles of intensive testing
The M.10 is a direct descendant of the M.9 "Aurora", Millikan Boats' first electro-solar catamaran. Used in the summer of 2024 during a voyage from Port Camargue to Cannes, the M.9 demonstrated its ability to sail autonomously, including in sustained weather conditions. Built in Caen, this prototype served as the basis for all structural and energy choices for the M.10, which now benefits from in-depth feedback, particularly in professional use.
A hull designed for energy efficiency and stability
The M.10 is based on a 10 x 3.40 m catamaran platform. The hulls have been redesigned using navigation data from the M.9 to maximize water penetration and reduce fuel consumption. The bow beam has been reinforced, integrating an electric windlass and chain hoist.
Energy capacity increased to 41 kWh for extended sailing
The M.10 integrates two 20 kW electric motors and a set of LFP batteries in optimized modules. On-board solar power now reaches 6 kWp, thanks to ten SUNPOWER Maxeon panels on the roof and two deployable side wings equipped with double-sided panels. Solar yield has been increased by 20% thanks to the reverberation of light on water, capitalizing on observations made with the M.9.
An organization designed for extended autonomous cruises
The interior space has been reworked to offer greater habitability than the prototype. Two double cabins, a convertible saloon, a full bathroom and a functional galley provide comfortable accommodation for up to seven people.
All the equipment is solar-powered, including the electric griddle, 120-liter fridge and water heater.
Redesigned ergonomics to facilitate short-handed piloting
Central control, two Garmin screens and an energy monitoring interface provide real-time readouts of production and consumption flows. A second screen displays solar and autonomy data. A map table completes the installation, with 220V power supply and 4G connectivity via Wi-Fi terminal.
A controlled move upmarket after a period of small-scale development
Manufacturing of the M.10 is based on high-precision molds and a numerically-controlled process, ensuring part repeatability and a high level of finish. The transition from prototype to series production has been designed to preserve the qualities observed on the M.9.
Complementary propulsion to extend navigation zones
Like the M.9, the M.10 can be fitted with a kite wing with dedicated fittings. This option makes it possible to switch off the motors while maintaining solar production, or to move closer to a shelter in the event of a breakdown.
With the M.10, Millikan Boats offers a mature version of a field-proven concept. By integrating the lessons learned from the M.9, particularly in terms of robustness and energy management, the shipyard is targeting a clientele of pleasure boaters and professionals who appreciate autonomy, silence and energy efficiency.
