Representing a significant era in British boatbuilding, the Berwick 31 is an aft cockpit model, sharing its basic hull design with other successful Westerly models like the Longbow, Pentland, and Renown. This approach allowed Westerly to offer variations on a proven platform, catering to different sailing preferences while maintaining a consistent standard of construction.
History and Design
The Westerly Berwick 31 was in production from 1973 to 1980, with 309 units built during this period. It was conceived as the twin or bilge keel version of the popular Westerly Longbow, a strategic move by Westerly Marine Construction Ltd. to broaden its appeal to sailors seeking reduced draft and the ability to take the ground. The Berwick 31 was also available as a ketch rig, offering further flexibility for various sailing styles.
Laurent Giles, the celebrated naval architect behind the Berwick 31, was known for a design philosophy that emphasized seaworthiness, stability, and comfortable cruising capabilities. The Westerly 31 range, including the Berwick, was described by Yachting World as an "ingenious design" that continued the successful theme of "good solid spacious cruisers" established by Giles and Westerly. During the 1970s, Westerly Marine Construction Ltd. built a strong reputation for producing sturdy fiberglass yachts through a "comprehensive scrutiny of design and construction," focusing on reliable and capable family cruisers with resilient glass fibre hulls. It is important to note that the Berwick 31 was built by Westerly Marine Construction Ltd. of Hampshire, England, a distinct entity from the U.S.-based Westerly Marine Inc.
Sailing Performance and Handling
The Westerly Berwick 31 is characterized by a design geared towards stability and comfortable cruising rather than outright speed. With a Sail Area to Displacement (SA/D) ratio of approximately 14.89, it performs reasonably well across a range of conditions but is not specifically optimized for light air. Its substantial Ballast to Displacement (B/D) ratio of around 0.453 indicates a high degree of stiffness, allowing the boat to stand up well to a breeze and providing a stable platform in a seaway. This high ballast ratio contributes significantly to its reputation for a comfortable motion.
The Displacement to Length (D/L) ratio of approximately 279.68 places the Berwick 31 firmly in the category of a moderately heavy cruiser. This weight class, combined with its twin keel configuration and 3.58 ft maximum draft, contributes to its solid feel and forgiving handling characteristics. Owners generally describe the Berwick 31 as a "capable and forgiving family cruiser" and a "good seaworthy boat" that can be easily single-handed. These characteristics make it a reliable choice for those prioritizing safety and comfort over high-performance racing.
Accommodations and Layout
The interior of the Westerly Berwick 31, while offering practical accommodation for its size, reflects the design philosophy of a robust cruiser from its era. As an aft cockpit model, the interior typically features a layout designed to maximize living space within its just over 30-foot length. The raised coachroof contributes to a decent maximum headroom, often around 6 feet, making the living spaces more comfortable for taller occupants.
While specific layouts can vary, a typical arrangement would include a V-berth forward, a head compartment, a salon with opposing settees that can often convert into additional berths, and a galley area. Storage is usually adequate for extended cruising, and the general finish quality features a blend of fiberglass and wood trim, typical of production yachts of the 1970s. Reviewers note that while the 31ft Westerly yachts offer reasonable accommodation, some may find the older models "rather cramped and spartan" compared to more modern designs. The wide side decks on deck provide safe and easy movement around the boat.
Owner's Perspectives
Owners of the Westerly Berwick 31 consistently praise its solid construction and its ability to handle various sea conditions with a comfortable and reassuring motion. Many appreciate its inherent seaworthiness, making it a trusted vessel for coastal cruising and longer voyages alike. The twin keel design is frequently highlighted as a significant advantage, allowing access to shallow anchorages and the ability to dry out, expanding cruising grounds.
Common maintenance themes among older Westerly models, which may also apply to the Berwick 31, sometimes include issues with the original deck fittings developing leaks, requiring re-bedding. Owners often undertake refits to modernize the interior and systems, ensuring the boat remains a capable and enjoyable cruiser for years to come. The strong community around Westerly yachts, including the Westerly Owners Association, provides a valuable resource for advice, parts, and shared experiences, reflecting the enduring appeal and robust nature of these British-built vessels.
