The Cygnus 20 FK is a compact and nimble monohull sailboat, designed by the renowned Canadian maritime architect George Hinterhoeller. Originally introduced in 1963 as the HR 20, it later became known as the Cygnus 20 after a class association was formed in 1965 or 1966. This particular fixed-keel (FK) variant was one of the models built by Skene Boats Ltd., a Canadian manufacturer known for producing accessible fiberglass sailboats. The Cygnus 20 FK is primarily conceived as an ultralight, high-performance daysailer or weekender, offering a lively sailing experience for its size.

The story of the Cygnus 20 FK begins with its designer, George Hinterhoeller, a significant figure in the Canadian sailboat industry who contributed greatly to fiberglass sailboat design, including his notable Shark 24. Hinterhoeller first built the vessel in 1963, naming it the HR 20. The boat's popularity led to the formation of a class association around 1965 or 1966, at which point it was officially renamed the Cygnus class. Boat Notes Production was undertaken by various builders, including Hinterhoeller Yachts Ltd. and Clarkecraft, before the tooling was eventually acquired by Skene Boats Ltd. in Ottawa. 5, 19, Boat Notes

Skene Boats Ltd., founded by Donald Skene in Gloucester, Ontario in 1968, operated during a pivotal era when fiberglass was revolutionizing boat construction. The company embraced this material, focusing on smaller, practical, and accessible sailboats. Although Skene Boats experienced ownership changes in 1970 and 1979 and ultimately ceased operations in 1992, their manufacturing ethos aligned well with the Cygnus's design philosophy of providing a functional vessel for recreational sailing. While the Cygnus 20 was also available in a centerboard version with a lighter displacement, the Cygnus 20 FK specifically features a fixed cast iron fin keel, contributing to its stability.

Sailing Performance and Handling

The Cygnus 20 FK, with its length overall of 20 feet and a waterline length of 17.5 feet, is characterized by its ultralight displacement of 950 pounds. This light build, combined with a fractional sloop rig and a total calculated sail area of 178.14 square feet, positions it as a very high performer for its size. Its design ensures it is stable and stiff under sail, capable of standing up to wind effectively. The boat is designed for responsiveness and agility, making it engaging to sail. While it is stable, its very light displacement and design mean it has a low righting capability if fully capsized, a characteristic common to some ultralight designs. With a theoretical hull speed of 5.61 knots, the Cygnus 20 FK offers brisk performance for a vessel of its dimensions.

Accommodations and Layout

Given its compact size, the Cygnus 20 FK offers basic yet functional accommodations designed primarily for day sailing or simple overnight stays. A notable feature described in its design notes is a "detachable coach roof/cuddy," which facilitates sitting headroom for up to four people, making the boat suitable for camping. Boat Notes While specific details on interior finishes or extensive layouts are limited, its design intent emphasizes practicality and maximizing usable space within its 7-foot beam. Owners typically find a simple, open cabin arrangement, fitting its purpose as an accessible small keelboat for recreational activities.
