It's important to note that while a builder article for "Westerly Marine Inc." was provided, the Westerly Longbow 31 was actually built by Westerly Marine Ltd. of Hampshire, England. This UK-based company was a leading European production builder of fiberglass sailboats throughout the mid-1960s and beyond, known for crafting "good solid spacious cruisers".
The Westerly Longbow 31 began production in 1972, following its initial launch in late 1971 and exhibition at the 1972 London Boat Show. The Longbow emerged from a period when Westerly Marine Ltd. was a significant player in fiberglass boat construction, under the managing directorship of David Sanders. The company's ethos focused on providing sound design and engineering solutions, resulting in boats known for their durability and practical accommodations.
The Longbow 31 shares its hull with other Westerly models such as the Berwick, Pentland, and Renown, forming a family of 31-footers. The Longbow itself is specifically characterized by an aft cockpit and a fin keel, though the broader 31-foot family also offered variations including centre cockpits, bilge keels, and ketch rigs. Laurent Giles, the designer, was celebrated for "ingenious design" and continued a successful theme of creating "good solid spacious cruisers" for Westerly.
Sailing Performance and Handling
The Westerly Longbow 31 is characterized by performance ratios that align with its role as a sturdy cruiser. With a Sail Area to Displacement ratio of approximately 13.3, she is not designed as a light-air flyer but offers steady performance in a range of conditions. Her Ballast to Displacement ratio of around 44.7% indicates a stiff and stable platform, capable of standing up to a good breeze and providing a comfortable motion in a seaway. Furthermore, a Displacement to Length ratio of approximately 268.5 suggests a moderate displacement vessel, striking a balance between light performance-oriented boats and heavier, more traditional cruisers.
Anecdotal accounts frequently highlight the Longbow 31's "excellence of accommodation and handling," noting it as a "fast yacht as well". Owners often describe her as a well-behaved boat that tracks well and feels solid underfoot, reflecting the robust construction and design philosophy of Westerly Marine Ltd.
Accommodations and Layout
The interior of the Westerly Longbow 31 is designed for comfortable cruising, typically configured with two cabins. Many models offer a generous maximum headroom of around 6 feet 3 inches, providing ample standing room for most individuals. The layout generally features a V-berth forward, a head compartment, a main salon with settees that can convert to berths, and a galley. Storage is usually plentiful, catering to the needs of cruisers who spend extended periods aboard. The finish quality is typical of its era, featuring robust fiberglass moldings complemented by traditional wood trim, creating a warm and functional living space.
Owner's Perspectives
Owners of the Westerly Longbow 31 generally speak highly of its solid construction and seaworthy capabilities. Many praise its comfortable motion offshore and its ability to cover significant distances reliably. The spacious interior, especially the noted headroom, is frequently appreciated for enhancing liveaboard comfort. Common strengths highlighted include the boat's forgiving nature, making it suitable for both experienced and less seasoned sailors, and its overall robustness, which has allowed many examples to remain well-loved and actively sailed decades after their launch.
As with any vessel of its age, prospective owners often look for specific considerations, such as the condition of original deck fittings, which may require re-bedding, and the integrity of the fiberglass balsa core deck and hull construction. However, the consistent theme from owner feedback suggests that the Longbow 31 is a highly regarded and enduring cruiser, offering a rewarding sailing experience and a comfortable home on the water for those who appreciate its classic British design.
