Transfluid - Bellmarine

Lanscape

Transfluid hybrid systems represent an innovative and sustainable solution for the propulsion of boats used by maritime high schools and for oceanographic boats. These technologies are particularly relevant in countries such as France, Norway, Spain and Denmark, where the attention to sustainability and protection of the marine ecosystem is particularly felt. In this article we will explore the characteristics of Transfluid hybrid systems, their use in various countries, and the benefits they bring to the study of marine fauna and flora.

Transfluid Hybrid Systems
Transfluid is a leading manufacturer of hybrid propulsion systems for boats. These systems combine internal combustion engines with electric motors, offering a versatile and efficient solution. The main features of Transfluid hybrid systems include:

– Reduction of Emissions: Electric motors significantly reduce emissions of CO2 and other pollutants, helping to protect the marine environment.
– Energy Efficiency: The combination of engines allows for optimization of fuel consumption, improving overall energy efficiency.
– Operational Flexibility: Vessels can operate in electric mode in sensitive or protected areas, and switch to combustion engine when necessary.
– Silence: Electric motors are much quieter than traditional combustion engines, reducing noise pollution and minimizing the impact on marine fauna.

Marine Hybrid Transmission
The HTM700 marine hybrid module allows you to navigate at normal cruising speed with the traditional internal combustion engine; furthermore it allows the use of the vessel in protected areas with zero-emission navigation and in ports or marinas, where silence and reduced pollution are highly appreciated characteristics. While sailing close to the coast, the silent propulsion enhances the landscape and when you are at anchor you do not need to have the engine running to use the on-board services. Thanks to these characteristics, the tranquility of the surrounding environment is not affected.

Navigation with the hybrid module allows different modes of use: in Electric mode you can navigate at low speeds without emissions; in Diesel mode you navigate by fully exploiting the power of the combustion engine, being able to decide whether or not to activate the battery charging function simply by operating a button on the dashboard. The Booster option allows you to add that of the electric motor to the power supplied by the combustion engine, not only at maximum power but above all in the transitional phase, where it is possible to optimize the rotation speed by intervening with the electric motor for small accelerations or for variations in speed.

The use of the HTM700 marine hybrid transmission system is suitable both for the creation of new boat models and for the transformation of existing ones. This allows you to have a modern and eco-sustainable boat, without having to replace it. This type of solution is suitable, among other things, for a series of activities in which comfort is important and the speed required is not extreme: non-displacement or semi-planing pleasure boats, boats for the transport of goods and passengers, for river tourism, for rental, fishing, rescue. This solution will be increasingly indispensable for navigating in protected areas, or for being able to navigate in full respect of nature and the surrounding area.

LEEN 56 TRIMARANS

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. The **DriveMaster** range of motors, including those used in the LEEN 56 and 72, has been widely adopted in both professional and leisure boating sectors worldwide. Known for their low maintenance requirements, energy efficiency, and compact design, Bellmarine motors have become a preferred choice for shipyards and boat builders looking to integrate green technologies into their fleets.

This expertise has made Transfluid and Bellmarine trusted partners, whose focus on eco-friendly and high-performance vessels aligns perfectly with Transfluid's mission to bring cutting-edge hybrid propulsion solutions to the maritime industry. The collaboration between these industry leaders showcases how advanced electric propulsion can enhance both the sustainability and performance of modern yachts.

A New Standard for Hybrid Yachts

The LEEN 56 and LEEN 72 set a new standard in the luxury yacht market by demonstrating that sustainability and performance can coexist. The hybrid propulsion systems provided by Transfluid and Bellmarine enable these trimarans to offer a unique sailing experience, combining the tranquility of electric navigation with the power and range of a thermal engine. As more yacht builders embrace eco-friendly technologies, the success of these hybrid trimarans signals a promising future for sustainable boating.
