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

Cruising on board the LEEN 51 promises to be a real pleasure. Thanks to its two electric motors in 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 draught ensure smooth and comfortable navigation, even in more challenging conditions. Additionally, the LEEN 51 is equipped with an indoor steering station in addition to the outdoor helm located on the flybridge, providing great steering flexibility. At anchor, the 2500W solar panels ensure comfortable and responsible autonomy. Maintenance is also effortless, with a spacious technical compartment (inspired by the NEEL 51) allowing for easy maintenance of this hybrid trimaran.

On the LEEN 51, the flybridge features a spacious surface of over 65 square meters, offering a welcoming space for guests. A large table is available for convivial meals, while sunbeds allow for relaxation during 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 safety during your movements on board the boat. You can move around with peace of mind, appreciating the available space to move comfortably. The trampolines allow you to enjoy pleasant moments of relaxation on comfortable sunbeds.

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.
