The Westerly 21 is a compact yet capable twin-keel cruising sailboat, designed by the renowned naval architect Laurent Giles and built by Westerly Marine Construction Ltd. in the United Kingdom. Produced for a brief period between 1977 and 1979, with only 53 units constructed, she quickly earned a reputation as a robust and surprisingly nimble small cruiser, appealing to those seeking a solid and secure vessel for coastal and estuary sailing. Her design prioritizes stability and ease of handling, making her a popular choice among entry-level sailors and those appreciating the practical advantages of a bilge keel configuration.

The Westerly 21 entered production in 1977, serving as an updated iteration of the earlier Warwick 21 model. This evolution saw several enhancements, including new windows, a Perspex sliding companionway hatch, and a notably smart, all-wood interior, which distinguished it from its predecessor. Naval architect Laurent Giles, known for his prolific career designing a wide array of sailing yachts since 1927, applied his philosophy of well-conceived and robust small boat design to the Westerly 21.

Westerly Marine Construction Ltd. (UK), the builder, was a dominant force in the British leisure yachting industry during the 1970s and 1980s, lauded for its commitment to quality GRP manufacturing. Their ethos centered on producing durable, family-friendly cruising sailboats that were built to last, a characteristic clearly evident in the Westerly 21. The boat was also notably offered as a kit, providing a more accessible entry point for some owners.

Sailing Performance and Handling

Despite her relatively "boxy shape" and the inherent characteristics of her twin (or bilge) keel design, the Westerly 21 offers "astonishing" sailing performance for a vessel of her size. This impressive capability is largely attributed to a combination of her long waterline and a comparatively tall rig. Owners consistently describe the Westerly 21 as a "most capable little boat" and a "very safe/stiff small cruiser," offering a secure and predictable motion in a seaway. The twin keel configuration provides excellent directional stability and the practical benefit of allowing the boat to dry out upright on mud berths or tidal grids, significantly expanding cruising possibilities.

Accommodations and Layout

For a sailboat just over 21 feet in length, the Westerly 21 boasts a surprisingly accommodating interior, characterized by its "smart all wood interior" finish. The layout is designed to maximize living space, offering four berths suitable for weekend cruising or extended trips for a couple. Inside, the main cabin typically features a settee berth on one side, ingeniously extending under the cockpit to provide a generous sleeping area, complemented by a quarter berth. The galley is equipped with practical amenities for its size, often including a two-burner Origo meths stove for cooking. While specific headroom details can vary, some owners report around 5 feet 9 inches in the main cabin, which is commendable for a boat of this class. The head, often a basic porta-potty or marine toilet, is typically situated in the forward cabin, sometimes discreetly located beneath the double berth. This efficient arrangement, which included an L-shaped starboard saloon berth, provided a practical and comfortable environment for its crew.

Owner's Perspectives

Owners of the Westerly 21 consistently praise the vessel for its solid construction, echoing Westerly Yachts' broader reputation for building robust boats that stand the test of time. Many appreciate its ability to serve as a very safe and stiff small cruiser, inspiring confidence in various conditions. However, some recurring points of discussion among owners include the potential for freshwater ingress around the engine hatch, an area that may require attention on older models. Additionally, there are anecdotal mentions of some owners "beefing up" the keels, suggesting that while generally robust, certain aspects might benefit from reinforcement over time. The active Westerly Owners Association forums serve as a valuable resource for specific knowledge and support among the community.
