The Kirby 36 represents a sophisticated intersection of high-performance naval architecture and meticulous Canadian craftsmanship. Launched in 1983 by Scorpio Yachts under the direction of Haydn Gozzard, the vessel was designed by the legendary Bruce Kirby, best known for the ubiquitous Laser and several America’s Cup challengers. The Kirby 36 was conceived as a 3/4-tonner during the peak of the IOR (International Offshore Rule) era, yet it was constructed with a level of interior refinement and structural integrity often absent in pure racing machines of that period. Built in Exeter, Ontario, the boat appealed to a specific demographic of sailors who demanded a vessel capable of winning club trophies on Saturday while providing a comfortable platform for family cruising on Sunday.

Sailing Performance & Handling

The Kirby 36 is defined by the "slippery" hull form characteristic of Bruce Kirby’s designs. It features a moderately deep fin keel and a high-aspect spade rudder, which together provide exceptional lift and responsiveness. While many IOR-influenced designs from the early 1980s suffer from "death rolls" or heavy weather helm due to pinched sterns, Kirby’s approach was more balanced. The boat tracks with surprising stability for a performance-oriented hull, a trait often attributed to Kirby’s ability to optimize the distribution of displacement.

Under sail, the masthead sloop rig is powerful, requiring a proactive crew to manage the large overlapping genoas typical of the era. In light air, the Kirby 36 is remarkably lively, easily out-sailing contemporary "condo-marans" and heavy displacement cruisers. When the wind freshens, the boat remains stiff, though it rewards early reefing to maintain its optimal heel angle. According to technical insights often shared within the Gozzard Yachts heritage community—the successor to Scorpio Yachts—the build quality provided by Haydn Gozzard ensured that the hull remained rigid under high rig tension, a critical factor in maintaining the boat's performance profile over decades of use.

Interior Comfort & Variations

Unlike many of its contemporaries that utilized stripped-out "galley-slav" interiors to save weight for racing, the Kirby 36 benefited from Scorpio Yachts' commitment to joinery. Haydn Gozzard’s influence is evident in the clever use of space and the high-quality wood finishes, typically featuring warm teaks or lighter ash. The layout is traditional yet functional, featuring a forward V-berth, a central salon with settees that double as sea berths, and a dedicated navigation station.

One of the most notable variations of this hull involves the specific interior appointments requested by early owners. While the hull remained a performance constant, some units were finished with more substantial cabinetry and amenities for extended coastal cruising, while others were kept minimalist for competitive racing. The boat's 11.5-foot beam allows for a surprisingly airy salon, and the headroom is generous for a vessel with such a sleek, low-profile coachroof. The craftsmanship of Scorpio Yachts ensured that even after forty years, the interior of a well-maintained Kirby 36 feels more like a custom yacht than a production boat.

Known Issues & Buyer’s Checklist

Prospective buyers of a Kirby 36 should focus on the specific structural areas common to high-performance boats of the 1980s. While Scorpio Yachts utilized robust layup schedules, the following areas require scrutiny:

  • Deck Core Integrity: Like many boats of this era, the Kirby 36 uses balsa-coring in the decks for weight savings and stiffness. Buyers should use a moisture meter or perform a percussion test around stanchion bases, chainplates, and the mast step to check for delamination or rot caused by hardware leaks.
  • Keel Bolt and Sump Inspection: Given its racing pedigree, some Kirby 36s may have experienced "hard groundings." It is essential to inspect the keel-to-hull joint for "smiles" or stress cracking in the fiberglass sump area.
  • Mast Step Compression: The mast is keel-stepped, and the structural block at the base should be inspected for any signs of compression or corrosion, particularly if the boat has been raced hard with high shroud tension.
  • Rudder Bearings: The spade rudder is under significant load; any "play" or vibration in the helm often points to worn rudder post bushings or bearings that may require replacement to restore the boat’s signature steering sensitivity.

Community & Resources

Owners of the Kirby 36 often find common ground with the broader community of Bruce Kirby design enthusiasts and Gozzard owners. While Scorpio Yachts was a relatively low-volume builder, technical support and historical context are frequently facilitated through Gozzard Yachts, which continues to provide a bridge to Haydn Gozzard’s early manufacturing legacy. Additionally, because Bruce Kirby’s designs—including the Kirby 25 and 30—were so prevalent in North American racing, technical knowledge regarding his rig tuning and hull shapes is widely available through regional PHRF (Performance Handicap Racing Fleet) associations.

The Verdict

The Kirby 36 is a rare "sleeper" in the brokerage market—a boat that offers the pedigree of a world-class designer and the build quality of a boutique Canadian yard. It is an ideal choice for the sailor who refuses to sacrifice the joy of a fast, responsive helm for the sake of interior volume.

Pros:

  • Exceptional Pedigree: A genuine Bruce Kirby design built by the respected Haydn Gozzard.
  • Versatile Performance: Equally at home on a racecourse or a weekend cruise.
  • High-Quality Joinery: Interior finishes far exceed the standards of typical 1980s production racers.

Cons:

  • Low Production Volume: Finding a well-maintained example can be difficult due to limited numbers built.
  • Age-Related Maintenance: Cored decks and IOR-era rigging require diligent inspection and potential investment.
  • Crew Requirements: The large masthead sail plan is most easily managed with an experienced crew in heavy weather.
