Meet our first viable concept. The 6 meter Hydrogen fuel cell electric foiling RIB. This boat is the fifth iteration, and she promises;
Electric propulsion
Electric propulsion
Electric boat propulsion is revolutionizing the maritime industry by offering a sustainable and eco-friendly alternative to traditional fuel-powered systems. Utilizing electric motors and batteries, electric boat propulsion significantly reduces emissions, noise, and environmental impact, making it an attractive choice for both recreational and commercial vessels. This technology not only contributes to cleaner waterways but also aligns with the global shift towards renewable energy solutions, marking a crucial step forward in the quest for more environmentally responsible maritime transportation.
Hydrogen powered
Hydrogen powered
The adoption of hydrogen as a power source for boats represents a promising frontier in maritime innovation. Hydrogen fuel cells, when used in boat propulsion, produce electricity through a clean chemical reaction between hydrogen and oxygen, emitting only water vapor as a byproduct. This emission-free characteristic addresses environmental concerns associated with traditional marine fuels, making hydrogen a sustainable alternative for reducing carbon footprints in maritime transportation. The versatility of hydrogen further enhances its appeal, offering the potential for extended range and quicker refueling compared to battery-powered systems. As efforts intensify to decarbonize the shipping industry, integrating hydrogen into boat propulsion emerges as a compelling and environmentally conscious solution for a more sustainable maritime future.
Hydrofoil flying boat
Hydrofoil flying boat
Hydrofoils have emerged as a cutting-edge technology in boat design, transforming conventional maritime dynamics. These specialized wings or foils, mounted beneath the waterline, lift the boat above the surface as it gains speed, reducing drag and increasing overall efficiency. The use of hydrofoils enables boats to achieve higher speeds with reduced fuel consumption, providing an eco-friendly alternative for both recreational and commercial vessels. This innovative approach not only enhances performance but also contributes to a smoother and more comfortable ride, minimizing the impact of waves. As hydrofoil technology continues to evolve, it holds the promise of revolutionizing maritime transportation by improving speed, fuel efficiency, and overall sustainability.
Foil optimized hull
Foil optimized hull
Our cutting-edge boat hull, meticulously optimized for hydrofoiling, represents a breakthrough in maritime design, embodying a synthesis of aerodynamics and hydrodynamics. Crafted with precision, the hull features a sleek and hydrodynamic profile, minimizing resistance and facilitating effortless lift as the boat accelerates. The integration of advanced hydrofoil technology further enhances performance, providing unparalleled stability and efficiency. Our optimized hull design ensures a seamless transition into hydrofoiling mode, delivering an exhilarating and eco-friendly experience. This innovation not only redefines the boundaries of maritime engineering but also sets a new standard for high-performance vessels, emphasizing speed, agility, and sustainability in the realm of hydrofoil-equipped boats.
Sustainable composite hull
Sustainable composite hull
Our boat hulls, constructed from sustainable or lightweight composites, epitomize a commitment to environmental consciousness and technological advancement. By incorporating innovative materials derived from sustainable sources or employing lightweight composites, we have successfully reduced the ecological footprint of our vessels while enhancing overall performance. These advanced materials not only contribute to the durability and strength of the hull but also result in a significant reduction in weight, optimizing fuel efficiency and maneuverability. As we navigate towards a more sustainable future, our boats exemplify the harmonious integration of cutting-edge technology and ecological responsibility, ensuring a seamless and exhilarating maritime experience with minimal impact on the environment.
up to 325 NM (600 km) range!
On a single fill up! The two high pressure hydrogen tanks will be able to carry 560 kWh energy in total, at 700 bar. This is good for 10 hours at 32 knots foiling cruising speed.
Maritime sustainability consultancy
Hydrogen electric boats are the result of an intensive study towards the possibilities to make boats per-emission. We gained much knowledge in the field of sustainable boats and zero-emission operation, which we love to share!
