Sirena Marine has entered the superyacht market with the debut of its 42-meter flagship, the Sirena 42M, at the 2026 Monaco Yacht Show. This new yacht is the first in a line that will expand to include 35-meter and 50-meter models, setting a new scale for the Turkish shipyard’s ambitions.
The Sirena 42M’s exterior and layout are the work of Milan-based designer Luca Vallebona, while the interiors come from Italian studio Hot Lab, part of the Viken Group. Naval architecture was developed by Van Oossanen Naval Architects, drawing on their experience with efficient, fast-displacement hulls. The result is a vessel with approximately 433GT of interior volume, built for extended periods at sea and a focus on comfort and versatility.
The 42M includes a two-deck private terrace for the owner, with a private retreat at the bow and a continuation above with sculpted sofas beneath wraparound glazing. The foredeck’s private terrace is open to the sky and framed by glass, directly connected to the full-beam owner’s suite via sliding doors. Freestanding armchairs, a pergola, and living plants create the sense of a secluded garden. The suite itself includes an office, dressing room, and en-suite bathroom. Above, the owner’s sanctuary continues with sculpted sofas tucked beneath wraparound dark glazing, providing privacy across two decks.
Inside, glass dominates the main saloon, with floor-to-ceiling windows and full opening aft doors. Solid wood walls, crafted to evoke flowing fabric, contrast with Italian limestone panels. The ceiling features swirling patterns of light from backlit wooden panels, a motif repeated in the carpets and walnut parquet flooring. Curved edges and rounded bouclé sofas add to the sense of softness throughout the yacht’s interiors. In the main lobby, a ripple effect is created by three-dimensional marble flooring and pendant lighting.
Accommodation is arranged for up to 11 guests in four en suite cabins on the lower deck, including two VIP doubles and two convertible twins. Ample storage, large hull windows, and a sculpted lobby contribute to a homely atmosphere.
The beach club is designed to extend waterside living, with a cascade of shallow steps leading to the swim platform. Fold-down wings expand the space to 71 square meters, and a glass-backed pool becomes a focal point for relaxation. The sundeck above is a flexible space, with a triple sun lounger, bar, dining area, and the option for an open-air gym, cinema, or hot tub.
Sirena Marine CEO Çağın Genç described the yacht as “a major milestone for the shipyard and the result of years of experience, investment and determination from our entire team.”
Powered by MAN V12-1450 engines, the Sirena 42M reaches a top speed of 16 knots and cruises at 10 knots. A 46,000-liter tankage provides a transoceanic range of 4,600 nautical miles. The yacht also includes a tender garage for a 5.65-meter tender and features such as stabilizers, air-conditioning, and a hydraulic swim platform.
The magazine has also looked at Kitson Yachts’ earlier Admiral superyacht project.
The Sirena 42M debuted at the Monaco Yacht Show as the first in a new line that will also include 35-meter and 50-meter models.
