Designed by Luca Vallebona with interiors by Hot Lab, naval architecture by Van Oossanen Naval Architects, and engineering by Eureka Yachts, the Sirena 42M marks the yard’s most advanced project to date.
Interior and Exterior Works Enter Final Phase
With the Sirena yacht now in its most advanced phase, work is progressing simultaneously across multiple areas of the yacht. Interior outfitting has moved into a decisive stage, with furniture installation underway across all decks as accommodation spaces begin to take their final shape.
On the exterior, the hull has reached one of its last major milestones before launch. The final primer has been applied, with the surface now undergoing sanding, inspection, and preparation ahead of topcoat application. This stage is critical in defining the finished appearance of the superyacht for sale, bringing together the clean lines and proportions established earlier in the build.
Technical installation is also approaching completion, with the engine room now around 85 percent finished. The main engine and key propulsion components have already been installed, with alignment work and chockfast pouring currently underway to ensure precision ahead of commissioning.
High-Volume Flagship with Flexible Layout
At approximately 433GT, the Sirena 42M stands among the highest-volume yachts in its class. The platform is built around Van Oossanen’s Fast Displacement Hull Form, developed to deliver efficiency across a wide speed range while maintaining stability and usable interior space.
The design builds on an approach first outlined when the yacht for sale was unveiled, where spatial flow and connection to the sea were central to the layout. Exterior and general arrangement by Vallebona are paired with Hot Lab’s interior concept, which draws on natural materials, curved forms, and a restrained palette to create a calm onboard environment.
The layout remains adaptable, with configurations that include a main or upper deck master suite, four guest cabins on the lower deck, and two VIP cabins designed to maximize beam.
Outdoor areas are equally central to the concept, with a large aft deck pool, fold-down bulwarks extending the beach club, and a forward owner’s patio that introduces private exterior space rarely seen in this segment.
The first Sirena 42M superyacht is listed for sale on YachtBuyer and is currently asking €23,950,000.
On Schedule for Summer 2026 Launch
The latest construction update confirms that the motor yacht for sale remains on schedule for its planned summer 2026 debut. With outfitting, system integration, and exterior finishing now underway, the yacht is entering the final stretch before launch and subsequent sea trials.
As Sirena Marine prepares to deliver its largest yacht to date, the 42M represents a step into the 40-meter-plus segment, building on the yard’s existing range while introducing a more complex, globally collaborative project.
According to YachtBuyer MarketWatch, the world's largest yacht database in the world, Sirena currently has 4 yachts either in build or on order. This includes multiple units of the Sirena 118.
