The LEEN 51 follows the path of the LEEN range with models (LEEN 56, LEEN 72) in terms of elegance, performance, comfort, autonomy, safety and comfortable sea voyages.

The LEEN 51 hybrid trimaran: adventure at full power

This LEEN 51 is much more than a motorboat. Designed by sailors, this trimaran is a hybrid boat, a true concentration of power and dynamism. Equipped with a Volvo Penta engine from 450 to 600 HP, this trimaran can reach a speed of 20 knots. In addition, its consumption of only 2 liters per mile at 10 knots is a true guarantee of reason and responsibility. Compared to other motor boats, whether monohulls or catamarans, the LEEN 51 consumes between two and four times less. With her standard electric motors, she can leave port in silence and enjoy pristine anchorages without emitting any pollution.

The cruising experience reinvented

Sailing aboard promises to be a real pleasure. Thanks to its two electric motors on each float, its maneuverability is exceptional, making it easy to pilot whether you are an experienced sailor or a beginner. Its considerable clearance and low draft ensure a smooth and comfortable ride, even in the most difficult conditions. In addition, the NEW is equipped with an interior steering station in addition to the exterior helm station located on the flybridge, providing great steering flexibility. At anchor, the 2500W solar panels ensure a comfortable and responsible autonomy. Maintenance is also easy, with a spacious technical compartment (inspired by the NEEL 51) that allows for easy maintenance of this hybrid trimaran.

The Flybridge, an oasis of well-being

In the LEEN 51, the flybridge has a large area of more than 65 square meters, offering a cozy space for guests. A large table is available for pleasant meals, while the sun loungers allow you to relax during the anchorage. A fully equipped outdoor kitchen (plancha, refrigerator, etc.) allows you to prepare delicious meals while enjoying the panoramic view. The generously wide side decks offer optimal security during your movements on board the boat. You can move with ease, assessing the space available to move comfortably. The trampolines allow you to enjoy pleasant moments of relaxation in comfortable loungers.

Brightness and elegance: enjoy the warm atmosphere

The interior layout of the LEEN 51 is unique in the world. With its main deck owner’s cabin, it offers an unmatched level of comfort and livability. You will benefit from twice as much living space compared to an equivalent-sized monohull. This trimaran offers 4 double cabins, each with its own shower and toilet, providing total independence and privacy to all occupants. The layout adopts proven design elements, with access to the floats from the inside and a pleasant living space offering a 270-degree panoramic view of the horizon. Moreover, the spacious and functional kitchen, as well as the intensely bright saloon, bring a touch of warmth and conviviality to the interior of the boat. Lastly, in the cockpit, you can accommodate up to 12 guests around the table, for friendly moments with family or friends.
