The UK X One-Design (XOD), a classic day racer designed by Alfred Westmacott in 1909, embodies a century-long tradition of competitive, strict one-design sailing. With an overall length of just over 20 feet, this iconic keelboat was originally commissioned by the Motor Yacht Club (now the Royal Motor Yacht Club) and has since fostered a passionate community, particularly around the Solent region. Known for its sensitive handling and balanced performance, the XOD provides thrilling boat-for-boat racing, appealing to a wide range of sailors from enthusiastic amateurs to seasoned professionals. While its initial design featured a gaff rig and a centerboard, the class has evolved to incorporate modern rigs and construction techniques, ensuring its continued relevance and competitiveness while honoring its rich heritage 2, notes.

InfoView listings

The genesis of the X One-Design dates back to 1909, when Alfred Westmacott, then Managing Director of Woodnutts Boatyard on the Isle of Wight, conceived the design. The original vision was for a gaff-rigged keelboat featuring a centerboard, setting the stage for a class dedicated to fair and equal competition. Production of the XOD has spanned decades, with records indicating that over 200 boats have been built, some as recently as 1994, underscoring the enduring appeal and robust class management 8, notes.

Over its extensive production run, the XOD class has demonstrated a remarkable adaptability. While maintaining its core one-design principles, the class association has thoughtfully permitted the adoption of modern rigs and building techniques. This evolution is reflected in the current fractional sloop rig, a departure from the original gaff rig, which allows for continued competitive racing while ensuring that older boats remain viable contenders [2,. Contemporary builders such as David Heritage Racing Yachts, renowned for their expertise in high-performance racing yachts and one-design classes, have played a role in the continued production and meticulous upkeep of XODs. Their commitment to precision and optimizing boats for racing aligns perfectly with the XOD's competitive spirit 5, 6, Builder Article.

Sailing Performance and Handling

Despite its compact size, the X One-Design is celebrated for its engaging sailing characteristics. Described as a "sensitive, well balanced and very enjoyable boat," it excels in providing pure racing pleasure. The XOD is characterized by a relatively heavy displacement for its length, requiring deep and powerful sails to navigate the often-choppy waters of the Solent. This weight contributes to a stable platform, allowing the boat to stand up to stronger winds, a critical attribute for its primary role as a racing keelboat.

Handling an XOD demands careful attention and skill. Owners note that the boat requires "careful tuning to achieve optimum performance," making it a "challenging" but rewarding vessel to sail, especially in tidal conditions. Its one-design nature ensures that success on the racecourse is predominantly a testament to the crew's skill and tuning prowess, rather than equipment disparities. The XOD's performance is not about outright speed in all conditions but about close, competitive racing and the nuances of helm feel and trim.

Accommodations and Layout

Given its design as a 20.68-foot day racing keelboat, the X One-Design prioritizes performance and on-deck functionality over extensive interior accommodations. The indicates that there is no specified maximum headroom, reinforcing the expectation of a minimalist internal layout. The primary focus of the XOD's design is its spacious and efficient cockpit, allowing for active crew movement and optimal sail handling during races. Any interior space would typically be limited to a basic cuddy cabin, providing rudimentary shelter for gear or brief respite rather than comfortable cruising amenities. Details on specific interior arrangements, such as galleys or dedicated berths, are not widely documented, as these features are not central to the boat's racing purpose.

Owner's Perspectives

The X One-Design boasts a vibrant and dedicated owner community, particularly active in the Solent area, with fleets competing in Hamble, Itchenor, Lymington, Poole/Parkstone, and Yarmouth. Owners consistently laud the "unbeatable" appeal of racing an XOD, citing the well-supported racing programs and the close, boat-for-boat competition that defines the class. The strict one-design rules are highly valued, ensuring that skill and tactical prowess are the deciding factors in regattas, rather than technological advantage.

Commonly praised attributes include the XOD's solid construction and its ability to remain competitive even after many decades, a testament to its original design and the class association's management. Owners appreciate the class's success in balancing traditional design elements with modern advancements, keeping the boats relevant without compromising their fundamental character. While maintenance costs can vary depending on whether work is self-performed or contracted to a boatyard, owners generally find the XOD to offer competitive and "hassle-free racing". The involvement of specialized builders like David Heritage Racing Yachts in modern builds and refurbishments further underpins the class's reputation for quality and performance, with their boats often achieving significant racing success.
