Sirena Yachts has shown the Sirena 118, the new flagship of its range, at the Cannes Yachting Festival, where it was among the largest boats on display. The yacht measures 36 metres overall, with a 7.8-metre beam and a gross tonnage of 279GT.

Naval architecture comes from German Frers, continuing his work with the Turkish yard, while the exterior lines were developed by Sirena's in-house design team and the interiors by Cor D. Rover. The hull is glass fibre, with carbon fibre in the upper decks and resin-infusion construction, used to reduce weight and maintenance requirements.

Standard power is a pair of 1,550hp MAN diesels, giving a cruising speed of 10 knots and a top speed of 16 knots. An optional package of two 1,990hp MAN V12 engines raises the top speed to 18 knots. The design team used CFD analysis on the hull geometry and removed the need for propeller tunnels by shaping the afterbody to reduce turbulence.

"We are exceedingly proud to be able to show the first Sirena 118, IKIGAI, at this year's Cannes Yachting Festival," said Cagin Genc, CEO of Sirena Marine. "Working with our own in-house design team and some of the best-known names in the business, we have delivered a yacht that stretches the advantages of composite construction well into the realm of superyachting."

"The result is an elegant, strong, reliable and seaworthy motor yacht, capable of travelling the world in comfort and safety," said Frers. "She represents a successful balance between performance and a smooth, comfortable ride, including when motoring upwind in challenging sea conditions."

The aft deck holds a lounge with sofas, linked by double opening doors to a salon with full-height windows. The owner's suite occupies the forward section of the main deck and opens directly onto the foredeck terrace. In the optional Owner Split configuration it connects by its own spiral staircase to a private office and lounge on the deck below, where a fold-down sea balcony faces the water. There are six guest cabins in total including the master, for up to 12 people, with accommodation for up to five crew in three cabins. The upper deck has a lounge and an aft terrace, with a sundeck above that can be laid out to each owner's specification.

The first hull, IKIGAI, has been extensively customised. Cor D. Rover's guiding principle for the interior was, in his words, "home, sea, home": the designer worked from the theme of exploration while keeping the spaces domestic in character.

"The design is built around exploration, the people who went first, went deeper, went higher, and the world they moved through to get there," said Rover. "Its shapes, colours and materials are drawn from the vessels and instruments of that world: riveted hulls, aircraft fuselage, vintage navy portholes, ship's compasses - reworked here into something that still feels warm and lived-in rather than literal. It's an interior about curiosity, movement, and the will to keep going."

In the salon, the ceiling is made of pressed leaves set between multiple layers of milk glass and backlit by natural light. Decorative surfaces use peacock feathers, and there are seashells in the counter tops. The spiral staircase between the owner's cabin and the private lounge below incorporates a two-storey vintage mirror: with the fold-down balcony open, the waves are visible from the bedroom above by reflection. The lower space is finished in a deep green wallcovering.

The palette runs to moss green, burgundy and mustard, with furniture sourced internationally and finishes that pick up natural materials or the effect of age. The owner also specified a large dining table in the upper deck lounge and, on the sundeck, an al fresco bar with seating under the carbon fibre hard-top.

"For us, this is precisely where the uniqueness of the Sirena 118 lies: the platform enables owners and designers to take bold colours, unconventional materials and bespoke details beyond pure visual expression and transform them into a real, functional and liveable interior," said Genc. "Each yacht can have a character of its own, yet every one remains part of the same design story - resulting in a boat conceived entirely around its owner."
