The Achilles 24 is a seminal example of the British "pocket cruiser" era, bridging the gap between a performance day-racer and a coastal voyager. Born from the board of Oliver Lee and refined by Chris Butler of Butler Mouldings Ltd., the yacht was originally envisioned as a more habitable evolution of the Ajax 23 racing keelboat. Launched in 1968, it became one of the most successful small GRP yachts in the United Kingdom, with over 600 hulls produced before production ceased. Its reputation is built on a narrow, sleek hull form that prioritizes sailing efficiency over the high-volume, beamier interior layouts that began to dominate the market in later decades. The model was produced in both fin-keel and twin-keel (bilge) configurations, with the former being highly prized for its competitive edge in club racing.

Sailing Performance & Handling
The Achilles 24 is frequently described as a "sailor's boat" because of its responsiveness and balance. With a narrow beam of just 7' 1" and a low-profile coachroof, the boat presents very little windage, allowing it to excel in upwind work. According to technical data maintained by the Achilles Yacht Owners Association, the boat handles with the nimbleness of a large dinghy, remaining light on the helm even when pushed.
The fin-keel version is particularly noted for its ability to point high into the wind, a trait inherited from its Ajax 23 ancestry. While the twin-keel variant offers the practical advantage of drying out in tidal harbors, it sacrifices a marginal amount of speed and tacking precision. In terms of sea-kindliness, the Achilles 24 is remarkably "stiff" for its size. Its Displacement/Length ratio suggests a boat that sits "in" the water rather than "on" it, providing a secure, predictable motion in a seaway that belies its 24-foot length.
Interior Comfort & Variations
Inside, the Achilles 24 reflects the design constraints of a hull optimized for speed and aesthetics rather than maximum living volume. The interior offers sitting headroom only, which may be a deterrent for those seeking a "floating cottage." However, the layout is remarkably efficient. Most models feature a four-berth arrangement consisting of two settee berths in the main saloon and a double V-berth in the forepeak.
The boat was offered in two primary deck configurations: the standard "Coachroof" model and the "Flush Deck" version. The Coachroof model provides slightly more perceived volume and light in the cabin, whereas the Flush Deck version—favored by racers—offers an unobstructed working platform and a sleeker profile. Interior joinery was typically functional, utilizing GRP moldings with teak or mahogany trim. While the galley and head (usually a chemical toilet or a small marine head under the V-berth) are rudimentary, they are sufficient for coastal hop-scotching and weekend cruising.
Popular Mentions & Media
The Achilles 24 achieved legendary status in the long-distance sailing community through the exploits of sailor Roger Taylor. His heavily modified Achilles 24, Mingming, became famous through his books and documentaries detailing his solo voyages into the high Arctic and his participation in the Jester Challenge. Taylor’s choice of the Achilles 24 for such extreme conditions stands as a definitive testament to the hull’s structural integrity and offshore capability, proving that the model's "fast cruiser-racer" label was well-earned.
Known Issues & Buyer’s Checklist
Prospective buyers of an Achilles 24 should focus on several age-related technical areas common to 1970s GRP construction:
- Deck Delamination: The deck is a sandwich construction. It is vital to check for "sponginess" or soft spots, particularly around the mast step and the forestay attachment point, which can indicate a compromised balsa or foam core.
- Chainplate Reinforcement: On early models, the chainplates (where the shrouds attach to the hull) should be inspected for signs of stress crazing in the gelcoat or movement in the bulkheads.
- Keel Bolts: For fin-keel versions, a thorough inspection of the keel-to-hull joint and the internal backing plates is necessary to ensure no significant rust or movement has occurred over the decades.
- Window Gaskets: The original acrylic windows were often set in rubber seals that perish over time; many owners have since replaced these with modern bolted and sealed units to prevent cabin leaks.
- Osmosis: As with most early GRP boats from the Butler Mouldings era, hull blistering is a possibility. While rarely structural, it is a significant factor in valuation and maintenance planning.
Community & Resources
The model is supported by a robust and active community. The Achilles Yacht Owners Association is the primary resource for technical manuals, original brochures, and a registry of hulls. This association is instrumental in keeping the class alive, organizing rallies, and providing a knowledge base for DIY restorations.
The Verdict
The Achilles 24 remains a premier choice for the purist sailor who values performance and seaworthiness over standing headroom. It is an affordable, "proper" yacht that can transition from club racing on Saturday to cross-channel cruising on Sunday.
- Pros:
- Exceptional upwind performance and pointing ability.
- Proven offshore durability and structural integrity.
- Low maintenance costs due to simple systems and modest size.
- Strong active owner association for technical support.
- Cons:
- Very limited interior headroom (sitting only).
- Narrow beam results in a more cramped cabin compared to modern 24-footers.
- Standard aging issues common to GRP yachts from the 1970s.
