French shipyard Océan Développement introduced a brand-new yachting concept with the unveiling of the MODX 70.
In a world that’s constantly seeking innovative technologies for sustainable alternatives, Océan Développement’s MODX 70 is a pleasure catamaran solely reliant on renewable energy, completely eradicating the need for fossil fuels. Known for specializing in ocean racing, Océan Développement aims to achieve full autonomy and zero carbon emissions during operation. This goal was met by carefully selecting materials and implementing advanced technologies and systems.
Performance sailing and renewable energy management
Performance sailing and renewable energy management The MODX 70 design integrates performance sailing expertise and renewable energy management within the yachting industry, creating a catamaran suitable for both coastal cruising and offshore adventures. Led by Océan Développement, in partnership with VPLP design, the project involved collaborations with specialized technology partners in the bio-composites industry, renewable energy mix, and electric propulsion engines.
The future of yachting: high performance and sustainability The 70-foot catamaran MODX 70 features two automated propulsion systems with inflatable wings on retractable masts and an electric motor system with variable pitch propellers for hydrogeneration. This process uses electromagnetic induction to generate electricity, providing up to 35% of the energy mix. The 21.33m hull can comfortably accommodate 8-10 guests and up to 3 crew members. This innovative yacht results from 10 years of experience in sustainability, accessibility, and performance. Designed to thrive in challenging sailing conditions, the MODX 70 ensures the ultimate cruising experience for its onboard adventurers.
Layout: Three configurations available The MODX 70 aims to inspire a new generation of boat design with its hybrid wing-electric motor, offering 100 miles autonomy (2 x 40 kW), 70 sq.m of solar panels, and a 230-kWh battery bank. These features ensure noise-free navigation. The sleek yacht is available in three colors: Iceberg, Linen, and Pearl Grey, with customizable interior designs using bio-sourced materials. Owners can choose from three configurations:
- Owner: Personalized layout based on the owner’s tastes, with optional extras including logistical and maintenance support and remote technical assistance.
- Eco-charter: Balances private use and charter operation, with all running and maintenance costs covered, and year-round crew support.
- Eco-expedition: Designed for owners and corporations dedicated to ocean preservation, combining eco-charter elements with involvement in scientific eco-expeditions.
Aeroforce: an automated and retractable wing system
A standout feature of the MODX 70 is its wing system utilizing inflatable envelope technology for airfoil shapes and wing retractability. Patented technical fabrics ensure the envelope remains airtight and rigid. This wing technology enhances aeronautical performance, with a controllable flap expanding the range of acceptable wind conditions. The carbon fibre mast is telescopic and motorised, allowing it to rise as the wing inflates and retract completely into the hull. The seamless mast and wing movements are automated, contributing to system accessibility and propulsion performance.
The MODX 70 combines the pleasure of assisted sailing with the comfort and security of a motor yacht. The ultra-lightweight elements result from extensive research and expertise by the VPLP firm, with a building process incorporating bio-sourced materials.
Aeroforce: an advanced and retractable wing system
One of the most captivating features of the MODX 70 is its wing system. The use of inflatable envelope technology is crucial for creating airfoil shapes while allowing for wing retraction. The technical fabrics used in this system are patented to ensure the envelope stays both airtight and rigid, even under low pressure.
The primary aim of this cutting-edge wing technology is to provide the aeronautical performance of thick airfoil profiles, a key component for the yacht’s ecosystem. By incorporating a controllable flap, the range of wind conditions that the boat can handle significantly increases. The carbon fiber mast is both telescopic and motorized, designed to automatically rise as the wing inflates and retract completely into the hull. The deflated wing is housed by the balestron rig and can be customized to meet the specific needs of the vessel.
The smooth movement of the mast and wing is fully automated and mechanized, enhancing system accessibility and propulsion performance. The MODX 70 blends the enjoyment of assisted sailing with the comfort and security of a motor yacht. The ultra-lightweight components of the MODX 70 are the result of extensive research and expertise by the VPLP firm, using a practical building process that includes bio-sourced materials.
An eco-friendly yachting experience
For centuries, wind has been the main source of energy for water travel. Over time, fossil fuel engines replaced wind power due to their high output, but they are highly damaging to the environment. Today, people are becoming more aware of their impact and seeking alternative methods to reduce their carbon footprint. Yacht designers have returned to wind power, creating more sustainable yachts that avoid fossil fuels.
The MODX 70 is designed to be the first yacht to self-generate energy, enabling endless travel with zero CO2 emissions—ideal for the eco-conscious adventurer. The team behind the MODX 70 sourced bio-derived materials like linen fiber, cork (a CO2 positive material), 38% bio-sourced epoxy resin, and PET foam with 30% recycled content. These materials were sourced locally and regionally in France, minimizing the environmental impact of production.
The ultimate goal was to create a yacht that operates entirely without fossil fuels, focusing on reducing carbon emissions throughout the yacht’s life cycle and production cycle. Achieving this required innovative technologies and a strong commitment from both the crew and passengers to make a difference.
A catamaran with a purpose
To combat increasing plastic pollution in our oceans, the MODX 70 team partnered with ‘Race for Water’, a non-profit organization dedicated to cleaning up oceans, lakes, and rivers, spreading their vital message. Additionally, the MODX 70 received the i-Nov7 prize in the sustainable and smart mobility category. The i-Nov Innovation Competition, funded by the French State through the France 2030 Plan, aims to support the rapid emergence of companies with the potential to become world leaders in their fields.
