Nautor Swan

Nautor Swan was founded in 1966 by Pekka Koskenkyla in Pietarsaari, Finland. The hundreds of years of Finnish boat building history, combined with the unforgiving landscape around the small town of Pietarsaari, where temperatures can fall to -30º C in the depths of winter and the sea can be frozen for up to five months of the year, inspired the vision of the founder to start the production of high-quality and high-performing sailing yachts, made for the those, like him, who had the passion for cruising and racing in full contact with the water and nature.

In the 80’s, Nautor Swan entered a new era with the appointment of German Frers as designer, who has since been responsible for the design of all Swan yachts, maintaining in their design that vital balance of competent racers, comfort and beauty. Over 700 yachts have been produced on the design of Frers, including his first Swan, the “Swan 51” in 1981, which was then followed by great successes, such as the “Swan 46 I and II” between 1983 and 1997; the “Swan 53” in 1986; the “new Swan 44” in 1985; the “new Swan 36” in 1988; the “new Swan 48” in 1995; to end up with the current models, including the Swan 54, Swan 60, Swan 66, Swan 80, Swan 95, Swan 105 and Swan 115, the new flagship of the SwanLine.

Today, Nautor Swan with close to half a century of heritage, is the leader in the luxury sailing yacht market and is globally recognised as the producer of exquisitely crafted yachts, capable of offering the perfect balance of style and performance.

The collaboration between German Frers Naval Architecture and Engineering and Sirena Marine has resulted in a series of remarkable designs since 2015, encompassing both sailboats and motor yachts.

Under this collaboration, German Frers has produced seven designs that showcase a harmonious blend of aesthetics, functionality, and performance. Each design is a testament to the meticulous attention to detail and the pursuit of excellence that define us.

Our collaboration has led to the creation of sailboats and motor yachts that embody the values of both entities. These vessels not only reflect the technical expertise and design acumen of German Frers but also incorporate Sirena Marine’s commitment to quality craftsmanship and brand development on a global scale.

Together, German Frers and Sirena Marine continue to push the boundaries of yacht design.
