The Windelo 50 is a 15.24-metre eco sailing catamaran from the innovative French builder Windelo, founded in 2019 with a mission to create environmentally responsible blue-water cruisers. The 50 serves as the entry point to the Windelo range, offering the brand’s full suite of sustainable technologies in its most accessible package.nnConstructed using proprietary basalt fibre and recycled PET/PVC foam sandwich, the Windelo 50 represents a radical departure from conventional fibreglass construction. This eco-conscious hull technology delivers comparable structural performance while significantly reducing environmental impact throughout the vessel’s lifecycle.nnThe hybrid propulsion system features twin 20 kW electric motors powered by a 1,120 Ah battery bank at 48 volts (53.8 kWh total capacity), supplemented by a 17.9 kW generator and 500-litre fuel tank for extended range. Solar panels, hydro-generation from the propellers, and optional wind turbines continuously replenish the batteries, enabling extended periods of emission-free sailing and manoeuvring.nnNaval architects Barreau and Neuman have created a hull form optimised for performance under sail, with a generous 7.95-metre beam providing stability and spacious living areas. Retractable daggerboards deliver a draft range from 1.03 metres to 2.32 metres, balancing shallow-water access with windward sailing efficiency.nnThe Windelo 50 accommodates up to 12 day guests across 4 cabins plus a skipper berth, with CE Category A certification for ocean passages. Available in three versions — Adventure for ocean autonomy, Yachting for comfort and quiet electric cruising, and Sport for performance — prices start from EUR 1,195,000 excluding VAT.

Her hulls are drawn for speed rather than show.
Windelo chose a short, low slung platform with a nacelle set well clear of the water, the kind of profile usually reserved for performance catamarans rather than cruising ones. There is no conventional cockpit; a sheltered passageway links the two hulls, closed off by a bathing platform that lifts at sea and lowers at anchor to open onto the water. Forward, the helm station sits at the foot of the mast, giving clear sightlines to the sails and a sliding window that turns it into an enclosed, quiet space when needed. Large windows run through the saloon and galley, and a tilting door across the stern lets the whole living space open directly onto the aft platform.
Beneath the eco credentials sits a genuinely integrated power system.
Twin 20 kW electric motors, drawing on a 1,120 amp hour lithium bank at 48 volts, drive the Windelo 50 in near silence at low speed, and the yard’s own figures put her electric only cruising at around 5 knots even once the batteries have been drawn down. A diesel generator of just under 18 kilowatts sits in reserve, with a second available as an option, while roughly 3,000 watts of deck mounted solar and in water hydro-generation keep the bank charged underway. Basalt fibre and a foam core made from recycled PET and PVC bottles form the hull laminate, a sandwich construction chosen for a lower environmental footprint without giving up structural performance.
Four cabins, eight berths, and a saloon designed to disappear into the outdoors.
The accommodation plan is flexible rather than fixed: Windelo builds the four cabin layout to each owner’s brief, and every aft cabin takes a corner porthole for natural light and a sense of the sea outside. The saloon sits forward of the cockpit rather than apart from it, its windows and tilting stern door opening the whole space to the platform behind. A dedicated office nook off the helm gives a private spot to work underway. Finish throughout favours light, practical materials over heavy joinery, in keeping with a yacht built to carry her comfort without carrying excess weight.
At anchor, the Windelo 50 turns her stern into a terrace.
Lower the aft platform and raise the tilting saloon door, and the boundary between cockpit and interior disappears entirely. The result is one continuous living space running from the saloon table to the water, large enough for a proper outdoor table and happy to host twelve guests by day. Side windows in the saloon and galley open outward rather than simply glazing the view, so the breeze moves through rather than around the cabin. It is a deliberately informal arrangement, built for owners who want the boat to work as hard at anchor as she does under sail between anchorages.
Her autonomy comes from the sun and the sea, not the fuel dock.
Solar panels across the coachroof, hydro-generation from the propellers while sailing, and an optional wind turbine all feed the 1,120 amp hour battery bank, with the standard generator stepping in only when needed. CE Category A certification signs off her suitability for open ocean passages, and her 500 litre fuel tank gives the generator plenty of reserve for longer crossings without sun or wind. Retractable daggerboards let her draught shrink to 1.03 metres for shallow anchorages, then extend to 2.32 metres when pointing upwind matters more than access.
