The Swan 50 MS (Motor Sailor) stands as a testament to Nautor's Swan's commitment to robust construction and offshore capability, even in designs that prioritize comfortable living. Introduced in 1976, this ketch-rigged cruiser, often referred to as the Nautor 50, was conceived by the legendary American naval architecture firm Sparkman & Stephens. She was designed for discerning owners seeking a yacht capable of serious bluewater voyages, offering a powerful motion and substantial accommodations, rather than outright racing speed. Built by the prestigious Finnish yard, Nautor's Swan, the Swan 50 MS embodies the builder's renowned quality and the timeless design principles of S&S from an era when yachts were crafted to endure the most challenging sea conditions.

History and Design
The journey of the Swan 50 MS began in 1976, marking a period when Nautor's Swan, under the guidance of Pekka Koskenkyla, was solidifying its reputation for high-quality, high-performance fiberglass yachts. G1, G5, G11 With only nine hulls produced, the Swan 50 MS represents a relatively exclusive chapter in the Nautor saga. The design, Sparkman & Stephens hull number 2207, reflects the firm's well-established philosophy for large cruisers of the era: prioritizing seaworthiness, comfortable motion, and robust construction suitable for extended offshore passages. During this time, Nautor's manufacturing ethos was characterized by an "unwavering commitment to excellence," utilizing fiberglass construction to achieve "consistent quality" and "robust construction with spirited sailing capabilities." G1, G5, G11 The "MS" designation, denoting "Motor Sailor," signals a focus on internal volume, protected living spaces, and an emphasis on engine power as a reliable means of propulsion, complementing the ketch rig's versatility. After its production run by Nautor, the molds for this design were later acquired by Siltala Yachts, who built a modified version known as the Nautical 52, continuing the legacy of this sturdy design.
Sailing Performance and Handling
With a length overall of nearly 50 feet, the Swan 50 MS presents as a formidable presence on the water, designed more for powerful cruising than agile performance. Her significant displacement of 51,000 lbs relative to her waterline length results in a very high Displacement to Length ratio of approximately 432. This places her firmly in the category of heavy displacement cruisers, suggesting a yacht built for comfort and stability in a seaway rather than light-air speed. Similarly, her Sail Area to Displacement ratio of around 11.16 indicates that she will require a good breeze to achieve her hull speed of approximately 8.21 knots. She is not a light-air performer but excels when the wind picks up, benefiting from her substantial mass to carry momentum through choppy conditions.
The ballast to displacement ratio of about 0.284, while not exceptionally high, contributes to a stable and predictable motion. Owners frequently describe the Swan 50 MS as a powerful, comfortable offshore cruiser, praising her robust build and ability to handle heavy weather with aplomb. G3, G4 The ketch rig provides excellent flexibility for sail reduction and balancing the helm in various conditions, allowing for efficient sail plans across a wide range of wind strengths. She is known for tracking well and offering a smooth, steady ride, making long passages more enjoyable, though she may require engine assistance in lighter winds to maintain speed. G3, G4
Accommodations and Layout
The interior of the Swan 50 MS, particularly due to its "Motor Sailor" designation, is designed for spaciousness and comfort, reflecting Nautor's dedication to luxurious yet practical living spaces. While specific headroom figures are not available in the provided data, reviews and owner accounts consistently highlight a generous and well-appointed interior. G5, G6 The typical layout often features a raised salon or deckhouse, providing excellent natural light and panoramic views—a hallmark of motor sailor designs. This arrangement typically includes a comfortable seating area, a well-equipped galley, and often a dedicated navigation station. G5, G6
Below decks, the Swan 50 MS generally offers multiple private cabins, commonly including a spacious V-berth or forward cabin, and an aft owner's cabin, often with its own en-suite head. A second head typically serves guests or the main salon. G5, G6 The finish quality is characteristic of Nautor's Swan, with extensive use of high-quality wood, such as teak or mahogany, meticulously crafted into sturdy joinery and trim. Ample storage is provided throughout the vessel for extended cruising, and ventilation is typically well-addressed with numerous opening ports and hatches. The overall impression is one of solid luxury and enduring craftsmanship, designed to provide comfort and functionality during long voyages. G5, G6
Owner's Perspectives
Owners of the Swan 50 MS, or its close derivative the Nautical 52, consistently commend its build quality and exceptional seaworthiness. G7, G8 Many praise its ability to handle challenging offshore conditions with a comfortable and predictable motion, making it a highly regarded choice for long-distance cruising. The versatility of the ketch rig is frequently cited as a significant advantage, allowing for effective sail management in varied wind strengths. G7 The spacious and well-appointed interior is also a strong point, offering a luxurious and livable platform for extended periods aboard. The reliability and accessibility of the robust Perkins engine are often noted as positive features. G7, G8
However, the boat's heavy displacement means it can be sluggish in light airs, often necessitating the use of the engine to maintain passage speeds. G7 As with any vessel of its vintage (produced in the mid-1970s), owners frequently mention the need for ongoing maintenance and potential upgrades to older systems, such as plumbing, wiring, and electronics. G8 While Nautor's construction is generally sound, original deck fittings may occasionally require re-bedding over time to prevent leaks, a common issue for many boats from that era. G8 Despite these typical considerations for older yachts, the collective sentiment is that the Swan 50 MS remains a highly capable and rewarding vessel for those seeking a stout and comfortable bluewater cruiser.
