Designed by experts and enthusiasts, the new LEEN-TRIMARANS range brings together all the qualities of power yachts designed for demanding owners: elegance, performance, comfort, great
autonomy, safety and remarkable sea passage.  A subsidiary of NEEL Trimarans founded in 2009, the LEEN range has modern and refined lines to ensure a unique and timeless look.  The NEEL Trimaran group is now the world’s leading designer and manufacturer in its field.

Created at the initiative of a team of professionals boasting over 40 years of experience in shipbuilding, offshore racing and long-distance sailing, the NEEL Trimaran group’s expertise is the result of the skill and strong commitment of the people who work there.

The company fosters a healthy R&D culture and this is confirmed by a whole array of international prizes awarded to its boats. (European Yacht of the Year 2018, Multihull of the Year 2018, Best Boat of the Year 2020, victory of the ARC+ 2019…).

• 30 models are produced each year under the expert hands of 120 employees.
• The firm’s projected turnover for 2020 is €20 million
• It has a share capital of €3 million

A Banque de France listing of G3 proves the company is financially sound and trusted within the financial community.

NEEL TRIMARANS has complete faith in the nautical capacity of the trimaran, be it powered by sails or an engine. It has already proven that, on high seas, there is no safer vessel.

The hydrodynamic resistance of its narrow hulls is extremely low.
Trimaran engines are of moderate size, by necessity, and very economical in fuel.

These vessels also have the advantage of being very stable out at sea. For cruising on high seas, a trimaran with an engine simply makes sense. This is why NEEL TRIMARANS decided to develop a motor-powered range too.

Introducing LEEN, the mirror image of NEEL!

LEEN Hybrid Explorer Trimarans

The LEEN Hybrid Explorer range of motor trimarans inherits all the renowned marine qualities of the NEEL and benefits from the same trimaran-building expertise.

These luxury vessels built for life at sea combine high-sea cruising standards with onboard comfort, autonomy and performance.

Pleasure-boaters are seeking to push out the boundaries thanks to yachts offering maximum self-sufficiency, performance, comfort and reliability. This is the ideal trimaran in which to embark on an expedition (transatlantic autonomy) or cruise off the coast.

LEEN Architects

Bernard Nivelt is considered to be one of the best naval architects of his time. He has designed many cruising vessels and high-performance racing trimarans.

Pierre Frutschi, an architect who qualified at the University of Geneva, is also a yachtsman and a reputed naval designer. He specialises in large-scale “one-off” models of between 40 and 100 feet, as well as mass-produced ranges.

Bernard Nivelt and Pierre Frutschi have known each other for a long time and now work together to achieve some great successes. NEEL-TRIMARANS called upon this brilliant duo, without hesitation and in total confidence, to design the company’s new range of engine-powered trimarans.

Production Methods

The expertise of NEEL-TRIMARANS is based on attention to detail, a sense of creativity, and industrial rigour.

The company has developed and tested its manufacturing techniques: assembly of composite panels infused on marble and assembled in a shaper. This method is particularly well adapted to the production of long, narrow, bilge hulls.

The structure of the deck and hulls is vacuum-infused, a procedure which ensures maximum weight, better composite quality and low environmental impact.

These production methods have been tried and tested, the costs are controlled and the quality is guaranteed.

Hybrid Engine

LEEN Trimarans are fitted with a heavy-duty, hybrid engine. This comprises a central heat engine and two electric side pods (beneath the hulls). The diesel engine is the main source of propulsion.

The electric pods are used:
• Coupled with the diesel engine during port manoeuvres (thus replacing the bow thruster), or
• As a silent electric engine to move off discreetly, or
• As a back-up engine when coupled with a generator.

With its cruising speed of 12 knots, it is possible to travel up to 300 nautical miles per day. Depending on the engine model chosen, a maximum speed of 15 to 18 knots can be obtained.

At cruising speed, the LEEN consumes less than 2 litres per nautical mile.


The staff of NEEL-TRIMARANS have been involved for a long time in the development of renewable energies, notably with the launch in 2018 of the NEEL 51 NOOS with its hybrid engine. So it is only natural that space is left onboard for solar panels and that the materials and equipment are selected and tested for reliability and longevity in order to limit the risk of built-in obsolescence.

The first LEEN has been sold to a client who already owns a NEEL 51. He is convinced that the trimaran is the best-performing and most suitable boat for long-distance sailing expeditions. This buyer particularly appreciates the uniqueness and innovating spirit of NEEL-TRIMARANS.
