The Turkish shipyard Sirena Yachts is making great progress in the construction of its largest model to date. The 42-metre flagship is currently being painted and the hull and superstructure are almost complete. Launch and seatrials are planned for mid-2026.

The Turkish shipyard Sirena Yachts has published the latest pictures of the construction progress of its largest model to date: the Sirena Superyachts 42M. The flagship is currently in the painting phase, with the hull and superstructure nearing completion. At the same time, the installation of the main systems, including the engines, is underway. At the same time, the carpentry work and interior fittings are progressing. The launch and sea trials are planned for mid-2026. A look at the Sirena 60.

International design

The Sirena Superyachts 42M was designed by the Italian duo Luca Vallebona (exterior and interior layouts) and Hot Lab (interior design). Both are part of the Viken Group. The Dutch studio Van Oossanen is responsible for the construction and has equipped the yacht with a highly efficient Fast Displacement Hull Form (FDHF).

This hull shape ensures efficiency and comfort at both high and low speeds. The interior volume of 433 GT is one of the largest in the 40 to 45 metre length range, and the values show an excellent ratio of space to length.

A journey from room to room

Other innovations on board the 42M superyacht include the Tier III-compliant propulsion systems, the hybrid-capable architecture for reduced emissions and silent operation, modern vibration and noise insulation and the use of environmentally friendly materials.

The designers describe the design of the Sirena Superyachts 42M as an "architectural journey". The concept invites passengers to experience the ship through textures and light, with each transition between areas having its own design rhythm - for a decelerated life on board and a deep connection to the sea.

The highlights of the Sirena 42M

Special features of the Sirena Superyachts 42M include the spacious master cabin with private patio, large outdoor terraces and the beach club with practical lowerable side walls. The layout of the Sirena Superyachts 42M models can be customised to suit the preferences of their future owners.

Example: The owner's suite can be located on either the main or upper deck, which allows for different configurations, such as a separate formal dining area in the saloon. There is also the option of creating an additional guest area in the bow for upscale dining or relaxation.
