Sirena 42M Debuts as the New Flagship for Sirena Superyachts

Making her global debut at the Monaco Yacht Show, the Sirena 42M marks an ambitious new chapter for Sirena Superyachts. As the flagship opening of a new three-model series from the Turkish shipyard, this four-deck steel and aluminium launch combines progressive naval architecture by Van Oossanen with timeless exterior lines from Luca Vallebona and sophisticated interior styling by Hot Lab.

Vallebona’s design centers on an extraordinary two-deck private owner’s sanctuary at the bow. A glass-lined main deck patio, complete with a shady pergola and lush real greenery, connects directly to the full-beam master suite. 

An elegant wood and metal staircase winds upward to an upper private terrace framed by wraparound dark glass, creating an outdoor retreat rarely seen on yachts of this class.

Alfresco living defines the remaining exterior spaces, starting at the waterside beach club. Shallow steps cascade down to a glass-backed pool integrated into the transom, flanked by fold-down wings that expand the area into a 71-square-meter beach club. 

Up top, the versatile sun deck offers a forward triple sunbed behind a curved glass windscreen, a shaded bar and dining area beneath a black hardtop, and flexible deck space for freestanding furniture.

Inside, Hot Lab brings an organic, water-inspired motif to life through fluid lines and exceptional Italian craftsmanship. Curved wooden walls mimic flowing fabric against panels of buttery Italian limestone and walnut parquet with seabed-contoured carpets. 

The main saloon features floor-to-ceiling glass and bouclé seating with rich green accents, while the main lobby’s sculpted marble and ceiling light evoke ripples from a water drop. Beyond the master suite, four lower-deck guest cabins accommodate up to 11 guests, complemented by an exceptionally finished guest-grade galley and quarters for nine crew.

Powered by twin MAN V12 engines, the fast-displacement hull exceeded expectations during sea trials, topping out at 16 knots. At a 10-knot cruise, her 46,000-liter fuel capacity delivers an impressive 4,600-nautical-mile transoceanic range, offering an ideal blend of long-range efficiency and high-end luxury.
