The Dragonfly 36, produced by the acclaimed Danish yard Quorning Boats, represents a pinnacle of the "Swing Wing" trimaran concept. Designed by Børge and Jens Quorning, this model—often identified interchangeably with the Dragonfly 35 in various markets due to its 10.68-meter hull length—is engineered for sailors who refuse to choose between the blistering speed of a multihull and the slip-accessibility of a monohull. The vessel is defined by its ability to retract its massive outriggers (amas) using a sophisticated geometry that does not require the stays to be loosened, allowing it to transform from a beam of over 8 meters to a manageable 3.85 meters for docking. According to the official Dragonfly 35 technical overview, this system has been refined over decades to ensure structural rigidity while under sail, making it one of the few high-performance multihulls capable of utilizing standard marina berths.

Sailing Performance & Handling

The sailing characteristics of the Dragonfly 36 are defined by its high power-to-weight ratio and the stability inherent in its three-point footprint. Unlike monohulls that dissipate energy through heeling, the Dragonfly 36 converts wind pressure into immediate forward motion. In a test by Sail Magazine, the boat demonstrated an ability to consistently sail at 10 to 15 knots in moderate breezes, with the "Ultimate" version—which features a taller carbon fiber mast and larger sail area—capable of exceeding 20 knots in ideal conditions.

The handling is noted for being remarkably light; the balanced kick-up rudder provides feedback more akin to a high-end dinghy than a 36-foot cruiser. Because the boat uses a retractable centerboard, it can navigate exceptionally shallow waters, drawing only 0.55 meters when the board and rudder are raised. On the wind, the narrow central hull and deep centerboard allow it to point as high as many performance monohulls, though it truly excels on a reach where the wave-piercing design of the amas reduces drag and prevents the "hobby-horsing" motion common in shorter multihulls.

Interior Comfort & Variations

Inside, the Dragonfly 36 utilizes the central hull’s volume with Danish precision, offering a level of woodworking and finish rarely seen in performance-oriented multihulls. The layout typically features a V-berth in the bow, a central salon with a folding table, a functional galley, and a surprisingly spacious aft cabin tucked under the cockpit. The interior is often finished in light woods like maple or teak to maximize the sense of space within the narrow 10-foot beam of the main hull.

The model is generally offered in two primary variants: the "Touring" and the "Ultimate." The Touring version is optimized for family cruising with an aluminum mast and a more forgiving sail plan. The Ultimate version targets the regatta circuit and speed enthusiasts, utilizing a carbon mast, high-tech laminate sails, and a deeper centerboard for enhanced lift. A notable sibling is the larger Dragonfly 40, which evolved from the 36/35 lineage, and the older Dragonfly 1200, which offers more interior volume but lacks the same agility.

The Dragonfly 36 (and its 35 counterpart) gained significant international acclaim when it was named the European Yacht of the Year in the multihull category. It has also been featured extensively in "Yachting World" and "Die Yacht" as a benchmark for folding trimaran technology. The model is a frequent sight in prestigious multihull regattas such as the Round the Island Race and the Silverrudder Challenge, where its ability to sail fast in light winds and maintain high average speeds in heavy weather is frequently documented.

Known Issues & Buyer’s Checklist

Prospective buyers of a pre-owned Dragonfly 36 should prioritize the inspection of the folding mechanism and the structural integrity of the beams.

  • Swing-Wing Bushings: The stainless steel pins and nylon bushings that facilitate the folding movement are subject to wear. Any "play" or knocking sounds while under sail can indicate that these components require replacement to maintain structural rigidity.
  • Beam-to-Hull Attachments: High-load points where the composite beams join the amas and the central hull should be checked for stress cracks or crazing in the gelcoat, which may suggest the boat has been pushed beyond its design limits in heavy seas.
  • Centerboard Trunk: Given its ability to beach, the centerboard and its trunk should be inspected for impact damage or debris-induced scarring that can hinder the lifting mechanism.
  • Stay Tensioners: The unique folding system relies on specific tensioning of the stays. Ensure the previous owner has maintained the specialized turnbuckles and that the rigging has been professionally tuned to prevent mast pumping.

Community & Resources

Owners and enthusiasts often congregate around the Dragonfly User Group, a long-standing technical resource and association dedicated to the maintenance and promotion of Quorning-built trimarans. This group provides a repository of technical manuals and peer-to-peer advice on everything from folding-hinge lubrication to sail trim optimizations.

The Verdict

The Dragonfly 36 is an elite-tier trimaran that offers a unique combination of speed, shallow-draft versatility, and high-quality craftsmanship. It remains one of the few vessels that can realistically transition from a transatlantic crossing to a shallow-water anchorage or a standard marina slip.

Pros:

  • Exceptional speed and acceleration, frequently outperforming 50-foot monohulls.
  • The "Swing Wing" system is the gold standard for folding multihulls, offering unparalleled docking flexibility.
  • High-end Danish interior construction provides a luxury feel rare in the multihull market.
  • Retractable appendages allow for beaching and exploring thin-water areas.

Cons:

  • Significantly higher purchase price and maintenance cost than comparable-length monohulls.
  • Interior volume is limited by the narrow central hull, making it feel smaller than a 36-foot monohull.
  • The folding mechanism requires consistent maintenance and specific technical knowledge.
