Sirena Marine will present its first 42.23m steel-and-aluminium superyacht at Monaco Yacht Show 2026, marking the public world premiere of the 433 GT flagship.
Sirena Yachts will stage the world premiere of its first Sirena Superyachts 42M at the Monaco Yacht Show 2026. The 42.23-metre yacht is the Turkish builder’s first steel superyacht and represents a major expansion beyond its established composite production models.
The Monaco Yacht Show’s official conference programme lists a dedicated Sirena Superyachts 42M world-premiere press conference for 23 September. The yacht was launched in July after completing final outfitting at Sirena Marine’s Yalova facilities.
The 42M has a Grade A steel hull and aluminium superstructure, with exterior design by Luca Vallebona, interior styling by Hot Lab and naval architecture by Van Oossanen Naval Architects. Detailed engineering is by Eureka Yachts.
Official builder specifications give an overall length of 42.23 metres, an 8.8-metre beam and a volume of approximately 433 GT. Accommodation is arranged for up to 10 guests in five cabins, supported by accommodation for up to nine crew.
One of the defining features is the forward owner’s patio, conceived as a private open-air extension of the owner’s suite. The main deck connects strongly with the aft exterior areas, while the beach club uses opening bulwarks to increase usable waterside space.
Sirena quotes a cruising speed of 10 knots, a maximum speed of 15 knots and a range of approximately 4,000 nautical miles at 10 knots. The yacht is powered by twin MAN engines rated at 1,450hp each.
The world premiere gives brokers, owners and the wider industry their first opportunity to assess the finished yacht against the renderings and construction updates released during the build. It is also an important test of Sirena Marine’s move into the larger steel-yacht sector.
The dedicated Monaco presentation is scheduled for 16:00 on 23 September. Superyacht Guide already carries the yacht in the fleet database and will update its record as further confirmed delivery and technical information becomes public.
