History and Design

The Nautor 50 was brought to life by Nautor's Swan between 1976 and 1978, with a limited production run of just nine hulls. During this era, Nautor, under the vision of Pekka Koskenkyla, was solidifying its reputation for producing high-quality, high-performance sailing yachts that married traditional Finnish boat-building craftsmanship with modern materials like fiberglass, which was used for the Nautor 50's solid hull and deck construction.

The "MS" in Swan 50 MS specifically denotes its motorsailer capabilities, suggesting a design where motor-assisted cruising or extended motoring in calm conditions was as much a consideration as pure sailing. This focus resulted in a vessel known for its robust construction, deep draft (5.58 ft), and substantial displacement, features well-suited for serious offshore work. The legacy of the Nautor 50 continued indirectly when its molds were later acquired by Siltala Yachts, leading to the development of the Nauticat 52, a testament to the enduring quality of its original design.

Sailing Performance and Handling

The Nautor 50's design ratios paint a picture of a heavy, stable, and comfortable cruising platform rather than a light-air racer. With a displacement-to-length ratio of approximately 431, she firmly sits in the category of a heavier, more traditional cruiser, suggesting a smooth motion in a seaway and the ability to carry significant stores for extended voyages. Her sail area-to-displacement ratio of around 15 indicates moderate performance, meaning she is not optimized for very light wind conditions but will certainly perform well once the breeze fills in, particularly with her ketch rig offering versatile sail plans for various conditions. The ballast-to-displacement ratio of approximately 0.286, while not exceptionally high, still contributes to her overall stability and ability to stand up to a decent amount of wind.

Owners and reviewers frequently describe the Nautor 50 as a robust and forgiving yacht, praised for its ease of handling and solid seakindliness, even in challenging conditions. The ketch rig offers flexibility in sail configuration, allowing for balanced performance and easy reefing. Its large, powerful Perkins 115hp engine complements its motorsailer designation, providing ample power for propulsion when sails are not sufficient or when making good time is paramount. The full fin keel and skeg-hung rudder contribute to excellent directional stability, making her a predictable and comfortable boat to steer over long distances.

Accommodations and Layout

The interior of the Nautor 50 is designed for maximum comfort and livability, reflecting its purpose as a long-distance cruiser and motorsailer. Common layouts typically feature a dedicated pilot house, often incorporating an internal helm station, which provides excellent visibility and protection from the elements, a significant advantage for colder climates or foul weather. Below deck, the accommodations are generous, often including a spacious main saloon, a well-appointed galley designed for offshore cooking, and multiple cabins to comfortably house owners and guests.

The finish quality is typical of Nautor's Swan from that era, characterized by superb craftsmanship, extensive use of high-quality wood joinery, and robust fittings built to withstand the rigors of bluewater cruising. Storage is ample throughout the vessel, essential for extended periods at sea. While specific headroom figures are not available, images and reviews suggest comfortable standing room in main living areas. Ventilation would typically be achieved through numerous opening ports and overhead hatches, crucial for comfort in warmer climates. The overall impression is one of a solid, comfortable, and highly functional interior, perfectly suited for extended voyaging.

Owner's Perspectives

Owners of the Nautor 50 (Swan 50 MS) consistently praise its exceptional build quality, comfort, and seaworthiness. The boat is frequently lauded for its robust construction and ability to handle heavy weather with confidence, offering a secure and stable platform for cruising. Many appreciate the combination of sailing capabilities and the powerful engine, which provides reliable propulsion when needed. The spacious and well-appointed interiors are often highlighted, making it a comfortable home for extended periods.

As with any yacht of its vintage, some owners note that ongoing maintenance of original systems, such as plumbing, wiring, and older electronics, can be a recurring consideration. However, the fundamental quality of the Nautor hull and structure is universally respected, making any necessary refits a worthwhile investment. The Nautor 50 is often described as a very capable and forgiving boat, making it a popular choice among those seeking a substantial, comfortable, and reliable yacht for serious cruising.
