Sirena Yachts' 42m flagship enters final outfitting ahead of upcoming launch

15 April 2026 • Written by Dea Jusufi and Emily Dawkins

Turkish yard Sirena Yachts has announced a construction milestone for its 42-metre superyacht and future flagship, which is scheduled for launch in early July. The final outfitting and finishing phase of the new build is now underway, with work progressing simultaneously across multiple areas of the yacht's decks. 

Interior outfitting is ongoing, with furniture installation taking place across the build's living spaces and accommodation, and the hull has entered its final finishing stage. The engine room is also nearing completion, with systems installation at an "advanced stage". 

Described as a "waterborne dream home", Luca Vallebona was selected to create the exterior and layout for the Sirena 42M, while Italian studio Hot Lab is the mind behind the interior spaces. Naval architecture has been developed by Van Oossanen Naval Architects, alongside engineering by Eureka Yachts

Accommodation is across four lower-deck guest cabins, with two VIP cabins featuring transverse beds. While the layout is customisable, the arrangement features an owner's cabin at the bow – a solution designed to provide direct access to a concealed forward patio with lounge chairs and a swing.

"Often, reference is made to large windows as a method to enhance the relationship between the interior and exterior," explained designer Luca Vallebona at the project's first unveiling. "In the case of Sirena, I wanted to take this concept a step further, ensuring not only expansive views of the landscape but also the possibility of physically stepping outside of the usually enclosed interior."

Interiors are Nordic-meets-Mediterranean, incorporating curves, large fillets, and plenty of plants for a relaxed, organic feel. Chosen materials range from natural beech and oak to cotton and chenille for the sofas. This results in a light and desaturated colour range which, according to Hot Lab, emphasises natural light. 

"The effect we wanted to achieve is certainly that of a studied environment rich in detail, but at the same time one that did not become mannerist at all costs," added partner and head of design at Hot Lab, Enrico Lumini. "The lines are essential, almost obvious, yet in their continuous chromatic and material contrast, they find strength and richness." 

Exterior renderings reveal an al fresco dining area on the sundeck and casual sofa seating on the main deck – both providing uninhibited views off the stern. The aft deck houses a large pool with sun loungers, complementary fold-out bulwarks and twin steps leading to a large swim platform. The design also caters to the younger generation's greater affinity for water sports with generous onboard storage for tenders and toys.

The Sirena 42M was unveiled at the 2022 Monaco Yacht Show and is part of a new range that also encompasses 35 and 50-metre models. The project is asking €23,950,000 with Ocean Independence and Northrop & Johnson. 

According to BOATPro, Sirena Yachts currently has six yachts in build, including three Sirena 88 units and the first Sirena 118.
