Design Brief & Intent
The core mission of the Hawksbill 24 was to provide a safe, affordable, and highly capable weekend cruiser for young families and shorthanded sailors. In the early 1980s, UK coastal sailing was defined by highly tidal drying harbors and mud-berths, making twin-keeled boats highly prized. However, many existing twin-keelers of the era were notoriously slow and prone to excessive leeway. Tucker’s brief was to create a boat that could stand upright on its own bottom on a receding tide while offering the spirited performance of a modern, fractional-rigged sloop.
Constructed in solid fiberglass (GRP), the Hawksbill 24 was built to a utilitarian standard. The interior joinery relied on a practical combination of molded fiberglass liners and marine plywood bulkheads. Rather than trying to emulate the heavy, dark teak interiors of larger luxury yachts, Yacht Haven kept the accommodation bright, open, and lightweight. It targeted buyers who prioritized functional seaworthiness and structural integrity over expensive cosmetic embellishments.
Layout & Configurations
Measuring 24.25 feet overall with a modest beam of 7.64 feet, the Hawksbill 24 utilizes its dimensions to maximize interior space. The deck configuration features a clean, low-profile coachroof that still allows for a respectable headroom of five feet, seven inches below. The interior is laid out in a classic four-berth configuration. This includes a V-berth in the forward cabin, which can be closed off with a curtain, and twin single settee berths in the main salon flanking a central companionway. A compact galley slide-out and an enclosed marine heads compartment made the boat significantly more liveable for weekend cruising than the smaller 18-to-20-foot pocket cruisers of the previous decade.
The underbody configuration is the defining engineering choice of the Hawksbill 24. While officially classified as a twin-keel or bilge-keeler, many owners refer to it as a triple-keeled boat. This is due to a shallow, molded central stub keel or skeg that runs along the centerline between two asymmetrical steel bilge plates. This arrangement allows the boat to draw only two and a half feet of water, facilitating entry into shallow creeks and allowing the hull to sit perfectly level on sand or soft mud during tidal cycles. The rig is a fractional sloop, which uses a larger mainsail and a smaller headsail, allowing for easier sail handling and precise control when tacking.
Sailing Performance & Handling
On the water, the sailing dynamics of the Hawksbill 24 are directly influenced by its design ratios. With a displacement of 2,756 pounds, the boat carries 1,000 pounds of ballast, yielding a robust ballast-to-displacement ratio of 36.47 percent. This high ballast ratio provides a strong righting moment, ensuring the boat stays relatively stiff and resists excessive heeling in moderate breezes. This directly compensates for the shorter leverage of its twin-keel configuration.
The displacement-to-length ratio of 166.19 places the Hawksbill 24 in the light-to-moderate displacement category. This indicates an easily driven hull that accelerates quickly in light airs. Combined with a powerful sail area-to-displacement ratio of 18.39, the boat is lively and responsive. It escapes the sluggish, sticky feeling common to older, heavier bilge-keelers. The fractional rig keeps the headsail small, making the boat exceptionally easy to manage single-handed.
However, its motion in a seaway is characterized by a low comfort ratio of 13.56. The motion is quick and snappy, meaning the crew will feel the waves and chop far more than they would on a heavier, traditional displacement boat. Additionally, the capsize screening ratio of 2.18 is above the traditional offshore threshold of 2.0. This confirms that while the Hawksbill 24 is an exceptional, stiff coastal and estuary cruiser, it is not designed to withstand massive breaking seas or the extreme rolling conditions of ocean passages. Like most bilge-keelers, it also exhibits slightly more leeway when sailing close-hauled than a deep fin-keel counterpart.
Known Issues & Triage
Decades after production began, several model-specific structural and mechanical vulnerabilities have emerged that require careful inspection and triage.
- Bilge Keel Flexing and GRP Fatigue: The high physical stresses placed on the hull-to-keel joints—particularly from decades of resting on the hard or drying out on uneven ground—can lead to localized flexing. The GRP laminate at the aft end of the bilge keel housings is a known stress point. Over time, this area can exhibit stress crazing, structural distortion, or hairline cracking. Triage requires a thorough inspection of the internal bilge floors and backing plates, and many owners choose to reinforce these areas with additional fiberglass laminations and heavy backing pads.
- Deck Core Wetness and Delamination: The deck structure of the Hawksbill 24 utilizes a plywood or balsa sandwich core to save weight. After forty years, the bedding compounds around the stanchion bases, chainplates, and the mast tabernacle inevitably dry out and fail, allowing freshwater intrusion. This leads to rot and localized deck softness. Suspect areas must be sounded with a plastic hammer, and soft spots must be drilled, dried, and either epoxy-injected or entirely recored.
- The Vire Petrol Engine: The original factory-installed auxiliary was a single-cylinder, six-horsepower Vire two-stroke petrol engine. While compact, these engines are now highly temperamental and difficult to maintain. Sourcing replacement parts is a major challenge, and the raw-water cooling passages are prone to severe salt buildup and corrosion, which can lead to overheating and head gasket failure.
- Hull-to-Deck Joint and Rubbing Strakes: The wooden rubbing strakes are fastened through the hull-to-deck joint. If the wood rots or the fasteners loosen, water can weep into the cabin sides, damaging the interior headliners and plywood cabinetry.
Modernization & Upgrades
Many surviving Hawksbill 24 hulls have undergone significant modernization, particularly regarding propulsion and electrical systems.
- Engine Conversions: Because of the unreliability of the original Vire petrol engines, the most common upgrade is a complete propulsion swap. Some owners refit the boat with a compact, single-cylinder diesel engine, such as a Yanmar 1GM10 or a Beta Marine 10, though this requires modifying the fiberglass engine beds 5. Alternatively, many owners opt for a simpler, more cost-effective solution by sealing the propeller shaft log, removing the inboard entirely, and installing a modern, long-shaft four-stroke outboard motor on a heavy-duty, adjustable transom bracket.
- Electrical System Simplification: The original wiring on these boats was minimalist and often utilized glass-fuse panels that are now prone to corrosion. Modern refits typically involve rewiring the vessel with marine-grade tinned wire and a consolidated DC breaker panel. Integrating a small, lightweight LiFePO4 battery paired with a low-profile solar panel on the coachroof provides ample power for LED lighting, a VHF radio, and modern tablet-based navigation tools without the need for a heavy engine alternator.
Market Snapshot & Economics
On the brokerage market, the Hawksbill 24 is classified as an entry-level pocket cruiser. Because of its limited production run, it is relatively scarce compared to mass-produced contemporaries like the Westerly Centaur or the Hunter Duette, but it frequently commands a loyal following in the UK and Northern European coastal markets.
Financially, the Hawksbill 24 is traded as a high-value, low-cost project boat. The economics of purchasing one hinge almost entirely on the state of the engine. Buying a boat with a non-functioning Vire petrol inboard and intending to professionally install a brand-new diesel engine is rarely economically viable, as the cost of the engine and installation can easily exceed the total market value of the boat. The most sensible economic path is to look for examples that have already been converted to reliable outboard power or those with a recently serviced, modern diesel auxiliary.
The Verdict
The Hawksbill 24 is an exceptionally clever, well-proportioned pocket cruiser that punches well above its weight. Thanks to Robert Tucker's design expertise, the boat balances the structural and practical advantages of a beachable bilge-keeler with a light-displacement hull form that is genuinely rewarding to sail in light-to-moderate conditions. While its quick motion in a seaway and lack of headroom limit its appeal for serious offshore voyaging, it remains an outstanding and economical choice for coastal exploration, estuary hopping, and single-handed weekend cruising.
