With naval architecture by German Frers, the Sirena 60 represents the next step in an ongoing evolution, a thoughtful refinement grounded in experience and guided by a clear understanding of what has proven successful in previous designs.

Generous hull volume allows for both comfort and practicality, with ample storage and unobstructed sightlines contributing to an open and inviting onboard atmosphere. Her refined hull form ensures a soft, stable ride across a wide range of conditions, offering both an impressive long-range cruising capability and the agility to increase speed when the journey demands it.

The Sirena 60 embodies balance between innovation and tradition, performance and elegance, purpose and pleasure.

YardHallberg Rassy
Year2025

The Hallberg-Rassy 370 new design continues the close collaboration between Frers Naval Architecture and Engineering and Hallberg-Rassy. It combines a modern, efficient hull with the classic proportions and balance.

Positioned between the 340 and 400, the 370 features a spacious aft cockpit with twin wheels and twin rudders for confident handling. The mainsheet system is placed in front of the windscreen, keeping the cockpit clear and functional, while the jib tracks on the cabin roof allow for precise upwind sailing.

The superstructure is equipped with 486 watt solar panels, specially shaped to cover the whole superstructure. The solar panels are fully walkable and feature anti-slip.

The result is a well-balanced yacht that sails easily in all conditions, reflecting Frers’ focus on performance, handling, and practical elegance at sea.

Year2024

We are proud to announce that Dragonfly, the 142.1-metre Lürssen Superyacht Project also known as Ali Baba, is currently undergoing sea trials near Brunsbüttel.
Frers Naval Architecture and Engineering was responsible for the exterior design which features four expansive decks and two dedicated helipads, exemplifying our unwavering commitment to excellence and luxury.

Drawing inspiration from the elegance and functionality of our previously designed 85.2-metre Lürssen yacht Pacific, this new design introduces innovative concepts that set new standards in superyacht design while maintaining the elegant lines which are our trademark.

We are excited as we approach the final stages and look forward to the delivery of this extraordinary vessel very soon.

“The Swan 128 perfectly embodies the Swan concept of the sporty cruiser, a yacht designed for long ocean voyages but also perfectly at ease in major international competitions, without needing to change any of its characteristics.”

The Swan 128, our project No. 1400, represents a milestone in the forty-year collaboration with Nautor. This partnership has flourished over the past decade, resulting in the launch of 13 new yachts—7 of which exceed 80 feet, the threshold distinguishing Swan Yachts from Maxi Swan Yachts.

“The new Swan 51 offers design and practical solutions that make the yacht comfortable and easy to sail from coastal waters to long offshore passages. The Swan 51 also features a mast which has been moved more centrally, further enhancing balance.
Ultimately, like all Swans, the 51 is a no-compromise sailing yacht, a pure sailor, more a sportscar than a limousine. It is designed to be reactive to steer and responsive to sail adjustments, bringing the sensations of sailing to life.”

German Frers 59m Classic Ketch design goes by the name of Maximus.

The construction commenced in 2021 at the renowned Zwartsluis facility located in the Netherlands. Boasting a rich history and unparalleled craftsmanship, Vitters Shipyard is responsible for bringing this exceptional project to life.

Renowned as one of the most influential superyacht builders in the world, Vitters Shipyard has garnered a reputation for its dedication to quality and innovation. Maximus is meant to become a remarkable addition to the global superyacht fleet, showcasing the epitome of luxury and design.

Visit Vitters website for more details and stunning images.

“SY Maximus is a 59 meter ketch designed by Frers Naval Architecture & Engineering and was delivered in December 2023.
She is a real wolf in sheep clothing with her classic hull lines, teak deck houses and sheltered cockpits. A true showcase of classic elegance.

However, below the waterline of maximus, it is all about performance. Twin rudders, lifting keel and optimized wetted surface area will stand for speed. Her sail and deck plan are optimized for competitive racing.

Last March during the St Barths Bucket regatta 2024 she made her debut in the racecourse.”
