The McConaghy Waszp is a revolutionary one-design foiling dinghy that transformed the landscape of high-performance sailing by making the "flight" experience accessible to a broader demographic of sailors. Developed by Andrew McDougall—the designer behind the world-beating Mach 2 Moth—and manufactured by McConaghy Boats, the Waszp was conceived as a simpler, more durable, and more affordable alternative to the fragile and expensive International Moth. Unlike the carbon-intensive, developmental Moth class, the Waszp utilizes a strict one-design philosophy, ensuring that racing remains a test of sailor skill rather than a battle of budgets. The boat features a robust hull construction and aluminum foils, which, while heavier than carbon, provide the necessary durability for launching and retrieving from beaches and ramps—a significant hurdle for traditional foiling craft.

Sailing Performance & Handling

The Waszp is engineered to provide the sensation of foiling in a package that is significantly easier to master than a developmental foiling skiff. It typically begins foiling in approximately 7 to 10 knots of true wind speed, depending on the sailor’s weight and technique. The boat utilizes a mechanical "wand" system mounted on the bow, which automatically adjusts the flap on the main foil to maintain a consistent ride height. According to Yachting World, the boat’s handling is characterized by its responsiveness; however, the aluminum foils provide a slightly more dampened and stable feel compared to the twitchy nature of all-carbon foilers.

The rig is unstayed, meaning there are no shrouds or forestay, which simplifies the rigging process and reduces the risk of entanglement during a capsize. Handling the Waszp requires a high degree of core strength and balance, as the sailor must manage the "hiking" moment on the solid wings while precisely controlling the mainsheet and tiller. When flying, the boat generates significant apparent wind, requiring the sailor to bear away and accelerate rapidly. Tracking is surprisingly stable once on the foils, though the transition from "low-riding" to "foiling" mode remains the most challenging technical hurdle for novices.

The Waszp has achieved significant cultural weight in the sailing world through its association with elite-level racing. Most notably, the class is the primary vehicle for the SailGP Inspire program, a global youth racing circuit that runs alongside the professional F50 catamaran events. This partnership has cemented the Waszp’s reputation as the premier stepping stone for young sailors aspiring to professional foiling careers. The boat is also the star of the "Waszp Games," an international championship that emphasizes both high-level competition and a social, inclusive atmosphere, distinguishing it from the often-insular Moth class.

Known Issues & Buyer’s Checklist

When inspecting a pre-owned Waszp, buyers should focus on the mechanical interfaces that facilitate foiling. While the boat is built for durability, the high loads of foiling take a toll on specific components:

  • Foil Alignment and Wear: Check the vertical foils for any play in the trunk. Excessive movement can lead to "foil hum" or instability at high speeds. Inspect the leading edges of the aluminum foils for nicks or "dings" which can cause cavitation and early stalling.
  • Wand Mechanism: The wand and its associated linkage to the main foil flap must move freely. Any grit or salt buildup in the bearings can lead to "over-foiling" (where the boat launches out of the water) or "crashing" (where the foils lose lift abruptly).
  • Wing Hinge Pins: The hiking wings are foldable for transport. Check the hinge points and pins for signs of fatigue or elongation, as these areas support the sailor's full weight during hiking.
  • Sail Condition: Waszp sails are high-tension film sails. Look for permanent creasing or delamination near the batten pockets, as a "blown-out" sail will make it significantly harder to generate the speed required to get onto the foils in light air.

Community & Resources

The Waszp is supported by a robust global infrastructure. The International WASZP Class Association manages the racing calendar and class rules, ensuring the one-design integrity remains intact. Owners also benefit from the "Waszp Hub," a dedicated technical portal that provides setup guides, tuning tips, and a global GPS ranking system where sailors can compare their top speeds and foiling percentages against others worldwide.

The Verdict

The McConaghy Waszp is the definitive entry point for sailors looking to join the foiling revolution without the complexity of a developmental class.

Pros:

  • One-Design Rigor: Ensures long-term value and fair racing where the best sailor wins.
  • Durability: Aluminum foils and robust hull construction allow for beach launching and easier handling.
  • Global Circuit: Unrivaled opportunities for youth and amateur sailors to race on an international stage.
  • Simplified Rigging: The unstayed mast and simple control lines make it possible to go from trailer to water in under 20 minutes.

Cons:

  • Weight: Heavier than a carbon Moth, meaning it requires slightly more wind to begin foiling.
  • Physicality: Requires a high level of fitness and agility to handle the high-speed maneuvers.
  • Learning Curve: While easier than a Moth, it still presents a steep challenge for those transitioning from traditional dinghies.
