Monte Carlo, Monaco — 23 September 2026 · world premiere at the Monaco Yacht Show.
Sirena's first superyacht makes its world debut at Port Hercule, already sold, and is the largest yacht the Turkish yard has built.
Sold before her world debut
Sirena announced the sale of the 42M weeks before her world debut at the Monaco Yacht Show. The yard calls her its largest and most ambitious project to date. The sale was concluded directly by Sirena Marine through its in-house commercial team.
Informality over rigid tradition
Sirena says the 42M was created for owners who value informality over rigid tradition, bringing space, light and freedom into one architectural experience. Mullion-free windows and interconnected living areas dissolve the boundaries between interior, exterior and sea. With its side balconies deployed, the beach club grows from about 61 to 71 square metres — 657 to 764 square feet.
A secret garden at sea
The Owner's Suite sits closer to midship for comfort under way and opens onto a secluded forward patio through full-height sliding glass doors. A custom pergola, a suspended chair, greenery and geometric ceramic surfaces give the patio the feel of a private Mediterranean garden at sea.
Four thousand miles at ten knots
The fast-displacement hull was developed by Van Oossanen for stability and a sea-kindly ride with efficient long-range cruising. Sirena gives her a range of 4,000 nautical miles at 10 knots and a maximum speed of 16 knots.
“We now look forward to presenting our flagship to the international yachting community at the Monaco Yacht Show, where she will make her highly anticipated world debut.”
