Launch in 2026 for the 42-meter Sirena Yachts designed by Luca Vallebona and Hot Lab
The yacht features interiors that represent the idea of a floating house, well-designed, elegant but sober, equipped with advanced technology.

The new 42-meter yacht under construction at the Sirena Yachts shipyard, designed by Italians Luca Vallebona (exterior and interior layout) and Hot Lab (interior design), with naval architecture by Van Oossanen, has passed the hull-superstructure union stage.
Work on the project is progressing according to plan, the shipyard adds, with the 42-meter Sirena Superyacht expected to be launched in 2026.
The Sirena 42M features open entertainment areas, spacious outdoor relaxation areas, and a distinctive master stateroom with private patio and a spacious beach club with fold-down bulwarks.
The model can be highly customized: the owner's suite can be located on the main deck or on the upper deck, which in turn allows for a dedicated dining area in the saloon or a more informal setting, as well as the creation of a guest area forward for fine dining or pure relaxation.
The owner's cabin, the release explains, blends in with the exterior with the sliding door at the bow, integrating all the patio elements—including a pergola, an optional pool, and an organically shaped staircase leading to the upper deck—into the interior design. "As a result, the bow cabin extends its outdoor area, creating a unique feature in today's semi-custom market."
The interior of the main deck is anchored by the aft saloon, which flows almost seamlessly into the aft pool, located a few steps below. Large windows enhance the connection with the outdoors, while the minimal use of side pillars ensures an uninterrupted panoramic view.
The lower deck houses four guest cabins, including two VIP cabins with transverse beds. A partition wall integrated into the wardrobe maximizes space efficiency, while the en-suite bathrooms provide separation from the technical areas aft, such as the garage and engine room, ensuring superior soundproofing. "The interior design skillfully combines curved and straight elements, using large connections and dynamic walls to maintain a balance between clarity and distinctive style."
The version with an extended living area features an aft lounge entirely dedicated to relaxation, as well as two highly customizable spaces.
The Sirena 42M's furnishings are characterized by a fresh, elegant, and innovative style, combining linear and curved geometries with warm, natural materials. The selected materials, such as beech, oak, cotton, and chenille, are combined with titanium-effect metal panels, creating a palette of light colors that reflect the sunlight.
The design blends Nordic style with a more relaxed Mediterranean atmosphere, with interiors that embody the essence of a meticulously designed houseboat, refined yet discreet, technically advanced, and naturally elegant.
