Windelo 50 Information, Review, Specs

Sailing Performance & Handling

Under sail, the Windelo 50 is a light and responsive machine, benefiting from its modest light displacement of approximately 11.2 tons. With a sail area-to-displacement ratio hovering in the high 30s, it resides firmly in the performance cruising category alongside names like Outremer and Seawind. In sea trials conducted by Sail Magazine, the yacht achieved speeds of 9 knots in 15 knots of true wind at a 60-degree apparent wind angle, demonstrating the efficiency of its slender hulls and deep daggerboards. The daggerboards provide a significant advantage in upwind tracking, allowing the boat to point closer to the wind than fixed-keel competitors.

Handling is defined by the centralized forward cockpit. All lines—including halyards, sheets, and reefing lines—lead to three winches located between the two steering wheels. This allows a solo watch-keeper to manage the entire sail plan without leaving the protection of the cabin house. A notable benefit mentioned in Yachting World (as reviewed by Toby Hodges) is the reduction of motion; because the helm is situated near the yacht's center of gravity, the pitching sensation is significantly diminished compared to traditional aft-helm designs. The electric propulsion system also provides a silent exit from the marina, with the two 20 kW motors providing approximately four hours of range at 5-6 knots on battery power alone before the generator is required.

Interior Comfort & Variations

The Windelo 50’s interior is a study in modularity and open-plan living. Because there is no traditional aft cockpit, the salon extends all the way to the transom, creating a "terrace" feel. The shipyard offers the 50 in three primary configurations: the Adventure, which is a robust version with unpainted basalt surfaces and durable materials; the Yachting, which features high-end finishes and more customization; and the Sport, which utilizes carbon fiber reinforcements to shave approximately 500 kg off the total weight. In newer versions of the model, the "garage-door" style lifting aft bulkhead has been replaced by more conventional sliding glass doors for better sealing and ease of use, according to editorial reviews in Multihulls World.

The hulls are voluminous despite the slender waterline, with the master suite typically occupying the port hull. A standout feature is the panoramic "corner" windows in the aft cabins, which provide nearly 270-degree views from the berth. Headroom remains generous throughout the nacelle and hulls, often exceeding 6'6". The galley is located on the main deck and is integrated with the forward cockpit, allowing the cook and the helmsman to communicate effortlessly. Variations in cabin count range from a three-cabin owner’s version to a four-cabin charter-style layout, with some owners opting to convert a forward cabin into a dedicated office space.

Popular Mentions & Media

The Windelo 50 has gained considerable attention in the nautical press for its environmental focus, earning a nomination as a Sail Magazine Best Boats 2025 Top 10 Nominee. The yacht's capabilities have been proven through high-profile voyages, such as the double Atlantic crossing performed by the hull Hakuna Matata, which reportedly utilized less than 800 liters of diesel for the entire journey by relying on its solar and hydrogeneration systems. More recently, the hull Joule has been featured in technical reviews for its upgraded solar capacity, now totaling nearly 6,000 watts.

Known Issues & Buyer’s Checklist

As a high-tech, semi-custom vessel, the Windelo 50 requires a specific inspection protocol:

• Electric Drive Reliability: The Bellmarine system and its integration with the 48V lithium bank are complex. Potential buyers should verify the firmware status and the health of the high-voltage battery cells, as well as the functionality of the hydrogeneration through the MaxProp propellers.
• Aft Visibility: The forward helm position offers excellent forward sightlines but creates a significant blind spot directly astern. Buyers should ensure that a high-definition aft-camera system is installed and operational to assist with docking.
• Hull Ventilation: Because the side decks and coachroof are often covered in solar panels, the number of traditional overhead deck hatches is limited. Owners on forums have noted that ventilation in the hulls relies heavily on portlights; in tropical climates, the efficiency of the air conditioning system or forced-air ventilation is a critical check.
• Basalt Fiber Repairs: While basalt fiber is resilient, it is less common than standard E-glass. Repairs require specific knowledge of the resin-to-fiber ratios used by the yard. A structural survey should look for any delamination or impact damage that may require specialized composite work.

Community & Resources

The primary resource for technical data and factory updates is the official Windelo Catamaran website. There is a growing community of owners who coordinate via private groups, often sharing data on energy consumption and system optimization. The shipyard maintains a direct relationship with its small fleet, often implementing feedback from current owners (such as the transition from the "garage" door to sliding doors) into new builds.

The Verdict

The Windelo 50 is a bold departure from the status quo, appealing to sailors who prioritize sustainability and innovative ergonomics over traditional aesthetics.

Pros:

• Exceptional energy autonomy via massive solar and hydrogeneration arrays.
• Superior protection and comfort for the watch-keeper in the enclosed forward cockpit.
• Lightweight, sustainable basalt construction offers excellent performance-to-displacement.
• Highly modular interior with panoramic views from aft cabins.

Cons:

• Significant learning curve for docking due to restricted visibility aft.
• Complexity of hybrid electric systems may challenge traditional marine mechanics.
• Higher initial purchase price compared to mass-produced 50-foot catamarans.
