Gdańsk-based Conrad Shipyard has delivered the latest superyacht from its C144s series to the client. The series represents Conrad’s line of luxury superyachts built in Poland. One of the earlier vessels in the series, now known as Ace, is the largest yacht of its type ever constructed in the country. The newly delivered yacht, named Miss Leen, is the third hull in the series.

Miss Leen measures 44.5 metres in length, 8.7 metres in beam, and has a draught of 2.6 metres. She has been registered under the Cayman Islands flag. The owner has not been publicly disclosed; however, Equasis lists Grande Maritime Services from the Cayman Islands as the registered owner, with Monaco-based Y.CO acting as commercial manager. The yacht was delivered to her owner in November and is currently stationed in the United Kingdom.

Naval architecture for the vessel was provided by Diana Yacht Design. Exterior deck spaces were designed by Nauta Yachts, while Reymond Langton Design was responsible for the interiors.

As with her predecessors Ace and Extra Time, Miss Leen features a full-displacement steel hull and aluminium superstructure. She has been conceived for long-range cruising. The yacht boasts a large beach club with direct water access, multiple saloons with dining areas, and a deck-level swimming pool. Additional amenities include bars and an al fresco cinema. Accommodation is provided for up to 10 guests in five cabins, including an owner’s suite with panoramic windows. The crew of nine are accommodated separately, with a dedicated captain’s cabin located on the bridge deck.

Propulsion is provided by twin Caterpillar C18 engines, each rated at 680 hp, enabling a maximum speed of 14.3 knots and a cruising speed of 11 knots. The vessel has a range of 4,500 nautical miles at 10 knots. Miss Leen also features a garage for a tender up to 7 metres, two full-size jet skis, and several seabobs. Construction of the yacht began in mid-2023 under the working title Project Moonlight. According to Boat International, Conrad Shipyard is already building another milestone vessel – Poland’s first 42-metre sailing yacht, which will also be the first flybridge sailing yacht of this size in the country. Meanwhile, a listing for the fourth hull of the C144s series has been live on YachtBuyer since July 2025, with completion expected in 2027. The asking price for this yacht is €32 million.
