A Sustainable Approach to Modern Yachting The LEEN 56 and LEEN 72 are hybrid trimarans designed to balance luxury, performance, and sustainability. These vessels are ideal for long-range voyages, equipped with sophisticated propulsion systems that maximize efficiency while minimizing environmental impact. The trimarans feature two **Bellmarine DriveMaster 20WEVO** electric motors in the LEEN 72 and two **DriveMaster 15W** motors in the LEEN 56, each with liquid cooling for optimal performance. These motors are highly reliable and designed to deliver a smooth and quiet navigation experience, making them a perfect choice for the modern eco-conscious sailor. What sets these systems apart is their ability to offer silent, emission-free propulsion while maintaining robust performance. The electric motors provide enough power for cruising at speeds of up to 7 knots, ensuring both vessels operate efficiently and responsibly. The electric systems also allow for quiet maneuvering in harbors, making docking and navigating tight spaces more comfortable for sailors Innovation in Hybrid Propulsion The LEEN trimarans are equipped with a unique hybrid propulsion system, with electric motors mounted on the outer hulls and a thermal engine in the central hull. This layout is designed to optimize the vessel’s performance in various conditions. The combination of electric and thermal propulsion gives sailors the flexibility to switch between power sources based on their needs. When sailing in calm waters or approaching a quiet anchorage, the electric motors can operate independently for a silent, emission-free journey. However, for longer distances and higher speeds, the central thermal engine provides the necessary power while maintaining fuel efficiency. The hybrid configuration is supported by a robust energy system, including a 48V lithium battery pack , which ensures continuous operation even on longer voyages. The efficient energy storage and delivery systems on board allow the trimarans to achieve impressive autonomy, making them suitable for extended cruising without frequent fuel stops. This combination of electric and hybrid technology not only extends the range of the vessels but also significantly reduces their carbon footprint, positioning the LEEN 56 and 72 as one among them examples of sustainable luxury yachts Transfluid and Bellmarine: Leaders in Electric and Hybrid Boating With over a decade of experience in developing marine propulsion solutions, Transfluid and its Bellmarine brand have earned a reputation for reliability and innovation.
