55 McConaghy 2026 Boat for Sale

The McConaghy MC55 is engineered for high-performance sailing, featuring an advanced carbon fiber mast and optimized rigging to maximize both speed and efficiency. Designed for effortless sail handling, this yacht incorporates cutting-edge sail technology to enhance cruising capabilities while ensuring ease of use for sailors of all experience levels.

Carbon Fiber Mast & Park Avenue Boom

At the heart of the MC55’s performance is its lightweight carbon fiber mast, which significantly reduces weight aloft, enhancing stability, speed, and handling. The Park Avenue boom allows for easy mainsail stowage and management, reducing effort when reefing or lowering the sail.

Precision Rigging & Sail Handling

The MC55 is equipped with high-performance standing and running rigging, ensuring optimal sail shape and control. The Reckmann electric furlers provide seamless deployment of headsails, while Harken electric winches offer precise control, even under high loads.

Versatile Sail Plan for Any Condition

The MC55 features a powerful upwind sail area of 150m², ensuring exceptional performance in light and moderate winds. The yacht’s fractional rig setup supports a variety of sails, including:

When fully deployed to 3.75m, the centerboards enhance upwind sailing efficiency, improving lift and reducing leeway.

Efficient, Safe, and Effortless Sailing
