The A Scow stands as the undisputed flagship of the inland lake racing world, a 38-foot marvel of engineering that blends 19th-century hull concepts with 21st-century materials. Often referred to as the "Queen of the Inland Lakes," the model is defined by its massive sail area and a flat-bottomed, scow-shaped hull that allows it to plane at incredible speeds even in moderate breeze. Originally conceived in the late 1800s, the design has been refined over decades by builders like Johnson Boat Works and eventually Melges Performance Sailboats, which brought the class into the modern era with carbon fiber components and asymmetrical spinnakers. Unlike traditional keelboats that rely on deep draft for stability, the A Scow utilizes a wide beam and twin retractable leeboards, making it uniquely suited for the shallow, shifting winds of freshwater lakes in the American Midwest.

Sailing Performance & Handling

The sailing characteristics of an A Scow are closer to a high-performance dinghy than a traditional 30-plus-foot yacht. Because of its flat hull and lack of a weighted keel, the boat is designed to be sailed at a significant angle of heel—typically around 20 to 25 degrees—which reduces the wetted surface area and allows the hull to "slice" through the water on its narrow edge. This creates a sensation of flight, particularly when the boat begins to plane. Editorial tests from Sailing World highlight the boat's responsiveness, noting that it can easily reach speeds exceeding 25 knots under the right conditions.

Handling is a choreographed team effort requiring a crew of six to seven. The dual-rudder system ensures that at high heel angles, at least one rudder remains fully submerged and effective. The transition from symmetrical to asymmetrical spinnakers, supported by the Melges "E-Z Launch" system, revolutionized the boat's downwind performance, making it faster and more manageable for amateur crews while maintaining its reputation as one of the fastest monohulls in the world.

The A Scow’s cultural footprint is deeply embedded in the history of the Inland Lake Yachting Association (ILYA). It is the centerpiece of the legendary "A-Invitational" and the ILYA Championship, events that draw the world’s top professional sailors to the lakes of Wisconsin and Minnesota. The boat has been featured extensively in sailing media as a pinnacle of performance, often compared to Volvo Ocean Race boats in terms of its power-to-weight ratio. High-profile sailors, including Buddy Melges himself, have used the A Scow as a training ground for America’s Cup and Olympic campaigns, cementing its status as a premier developmental platform.

Known Issues & Buyer’s Checklist

Prospective owners of an A Scow, particularly older hull versions, should focus on structural integrity and the evolution of the rigging.

  • Hull Stiffness: Early fiberglass models or those that have seen heavy racing may exhibit "oil-canning" or flex in the hull. Stiffness is paramount for maintaining the rig tension required to keep the forestay tight.
  • Leeboard Trunks: The twin leeboard trunks are under immense lateral load. Inspect for stress cracks or water intrusion in the core around the trunk mounts.
  • Rigging Loads: The A Scow uses a highly tuned rig. Check the chainplates and the mast step for signs of compression or fatigue, as the tension required for the modern square-top mainsail is significant.
  • Hardware Modernization: Older boats (pre-2000s) may still have hardware configurations for symmetrical spinnakers. Converting these to the modern asymmetrical setup is a common but expensive upgrade that involves installing a carbon bowsprit and modifying the deck layout.

Community & Resources

The A Scow community is one of the most dedicated in sailing, centered around the National Class A Scow Association (NCASA). This organization governs the class rules, ensuring that even as technology evolves, the fleet remains competitive and the one-design nature is preserved. Technical support and replacement parts are primarily sourced through Melges Performance Sailboats, which remains the primary steward of the design’s modern evolution.

The Verdict

The A Scow is not a boat for the casual cruiser; it is a specialized racing machine that demands high physical effort and technical skill. It offers a level of raw speed and excitement that few other monohulls can match, particularly in the context of lake racing.

Pros:

  • Exhilarating speed and early-planing capabilities.
  • Deeply established racing circuit with high-level competition.
  • The "E-Z Launch" spinnaker system makes the massive sail area manageable.
  • Strong resale value within the inland racing community.

Cons:

  • Requires a large, skilled crew of 6–7 people.
  • Limited to inland lake environments; not suitable for heavy offshore chop.
  • High maintenance requirements due to the extreme loads on the rig and hull.
  • Zero interior amenities or comfort features.
