Westerly GK 24 Information, Review, Specs

Sailing Performance & Handling

The GK 24 is a product of early IOR design philosophy, characterized by a generous beam (9' 2") relative to its overall length and a pinched stern. This geometry makes for a stiff, powerful boat when sailing upwind, though it requires active trimming to prevent excessive weather helm in heavy gusts. With a displacement-to-length ratio that leans toward the light-displacement end of the spectrum for its era, the boat is notoriously "twitchy" and responsive, rewarding a crew that pays attention to sail shape.

The model was offered with two distinct rig configurations: a 7/8 fractional rig and a masthead rig. The fractional version is widely considered the "sailor’s choice," offering better control over mast bend and mainsail flattening, which is essential for racing. According to technical data maintained by the Westerly Owners Association, the boat’s deep fin keel (drawing 4' 11") provides excellent lift, allowing it to point higher than many of its more cruising-oriented contemporaries. While a twin-keel version was produced for those in drying harbors, it sacrifices a significant degree of the windward performance that defines the GK 24’s identity. In a breeze, the boat is surprisingly sea-kindly for a 24-footer, though its light weight means it can be "lively" in a chop.

Interior Comfort & Variations

For a boat designed with a primary focus on racing, the interior of the GK 24 is surprisingly functional, if somewhat spartan. The layout is a classic four-berth arrangement: a V-berth in the forepeak and two settee berths in the main saloon. Because the boat was built during a transitional period for Westerly, two distinct interior finishes exist. The "Racing" version featured a stripped-back, weight-conscious interior with basic moldings, while the "Cruising" variant included more wood trim and additional stowage.

Headroom is limited—approximately 5' 8"—which is common for a Quarter Tonner but can feel cramped during extended stays. The galley is rudimentary, typically consisting of a two-burner stove and a small sink located near the companionway for ventilation. The "head" is usually a marine toilet situated under the V-berth, a common compromise in 24-footers of this vintage. Sibling models built on the same racing ethos include the larger GK 29 and the rare GK 33, both of which applied the same Laurent Giles design principles to larger platforms.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a GK 24 with a focus on its structural integrity and mechanical age, as many of these boats have been campaigned hard in club racing.

• Deck Compression: A common issue occurs at the mast step. Over years of high rig tension, the deck core can compress or the internal support post can settle, leading to "crazing" in the gelcoat around the mast foot.
• Keel-to-Hull Joint: Given its deep fin keel and racing history, the "Westerly Smile"—a crack at the leading edge of the keel-to-hull joint—is a frequent find. While often superficial, it can indicate loose keel bolts or past groundings.
• Headlining "Sagg": Like many British boats of the 70s and 80s, the foam-backed vinyl headlining is prone to catastrophic failure. The foam disintegrates over time, causing the fabric to sag and leave a sticky residue.
• Original Engines: Many GK 24s were originally fitted with the single-cylinder Bukh 10 or Yanmar 1GM. These engines are now reaching the end of their service life; buyers should check for signs of heavy smoking or cooling passage blockage due to salt buildup.

Community & Resources

The GK 24 benefits from one of the most robust owner support networks in the world. The Westerly Owners Association is an invaluable resource, providing access to original brochures, technical specifications, and a community of owners who have documented nearly every possible repair for this specific hull. Additionally, because the boat was a Laurent Giles design, the Laurent Giles Archive maintains high-quality digital copies of the original lines and construction drawings for those undertaking major restorations.

The Verdict

The Westerly GK 24 is an exceptional value for the sailor who prioritizes performance and handling over standing headroom and "floating cottage" amenities. It remains a competitive club racer and a capable coastal hopper for those who appreciate a boat with pedigree and spirit.

Pros:

• Excellent windward performance and responsiveness.
• Very affordable entry point into the world of performance sailing.
• Exceptional community support and technical documentation.
• Stronger build quality than many pure-racing Quarter Tonners.

Cons:

• Limited headroom and cramped interior for four adults.
• "Twitchy" handling requires constant attention in heavy weather.
• Likely to require cosmetic interior updates (headlining).
• The IOR-influenced "pinched" stern can make for an uncomfortable motion downwind in a following sea.
