Sirena 138' 5'' 42
Sirena Yachts has begun construction on its first 42-meter superyacht and future flagship. Originally unveiled in 2022 at the Monaco Yacht Show, the Sirena 42 is part of a new superyacht series that also includes 35- and 50-meter models.
She is offered exclusively for sale in the Americas with Northrop & Johnson at an asking price of €23,950,000, with delivery scheduled for the third quarter of 2026.
The new Sirena superyacht line is being built in steel and aluminum at the shipyard’s Istanbul facility. Her striking exterior is designed by acclaimed Italian designer Luca Vallebona, while the naval architecture is by the renowned Dutch firm Van Oossanen Naval Architects. The interior, fully customizable to the owner’s preferences, offers a variety of layout options — including the possibility of placing the owner’s suite on either the main or upper deck. This flexibility allows for a dedicated formal dining area in the main salon or a more casual configuration, as well as the option to create a guest lounge or entertainment space forward.
Guest accommodations are located on the lower deck, with four staterooms including two VIP suites featuring transverse beds. The suggested layout also places the owner’s suite forward with direct access to a private patio — an innovative feature that connects the interior to the outdoors, offering sweeping views and the rare ability to step directly outside from the suite.
The 42-meter’s flexible design ensures every yacht can be tailored to the individual owner’s lifestyle. Whether prioritizing formal entertaining spaces, private retreats, or open social areas, the layout options are designed to deliver a completely bespoke experience.
