McConaghy has long been recognized for building some of the world’s most advanced racing sailboats. Today, that same precision and innovation are driving their entry into the power catamaran segment—offering vessels that blend cutting-edge materials, luxury comfort, and serious performance.
Focused on carbon fiber construction, intelligent design, and bespoke interiors, the McConaghy power catamaran lineup brings a fresh, modern edge to the luxury yacht world. This article explores every detail of the McConaghy power catamaran lineup—from design philosophy and technical specifications to onboard technology and pricing.
Overview of the McConaghy Power Catamaran
McConaghy’s power catamarans are a bold departure from conventional luxury multihulls. They are designed to deliver minimal resistance through the water, reduced noise, and an exceptional level of customization.
Initially recognized for their sailboats and racing craft, McConaghy applied their composite mastery and hydrodynamic expertise to develop a range of power catamarans that are fast, efficient, and remarkably stable. These vessels combine elegant aesthetics with naval architecture optimized for performance, stability, and luxury.
What sets McConaghy apart is its aggressive focus on carbon fiber construction and engineering intelligence, a legacy inherited from decades of building America’s Cup and Volvo Ocean Race yachts.

All models feature spacious decks, flybridge options, and generous interior layouts that can be tailored to suit a variety of uses—from private yachts to commercial charters.
Revolutionary Construction & Materials
Carbon Fiber Monocoque Hull
A defining characteristic of McConaghy power catamarans is the use of carbon fiber monocoque construction. Unlike traditional multihulls that use segmented, stitched hulls with separate internal frames, McConaghy molds its hulls and decks as a single carbon fiber shell. This results in:
- Increased structural integrity
- Reduced weight for better performance
- Higher resistance to torsional stress
This method mirrors the construction of high-performance racing yachts, giving McConaghy vessels their unmatched rigidity and responsiveness on the water.
Stabilization Systems
McConaghy catamarans are built with active stabilization systems that ensure smooth motion even at high speeds or in rough sea conditions. Their wide beam and shallow draft contribute to inherent stability, but additional tech like Seakeeper gyroscopic stabilizers or interceptors can be integrated to virtually eliminate roll.
Deck Innovations
A hallmark of the McConaghy design ethos is a focus on usability and ergonomics. All deck areas are crafted to maximize space efficiency, safety, and luxury:
- Flush deck transitions
- Hydraulic swim platforms
- Fold-down bulwarks that transform into sun terraces
- Integrated tender garages and water toy storage
These innovations ensure that guests enjoy seamless indoor-outdoor flow and direct access to the water.
Powertrain & Sustainability
Propulsion Options
McConaghy offers various propulsion packages depending on the owner’s cruising needs, from twin diesel engines for long-range power to hybrid-electric options for eco-conscious travelers. High-speed configurations with Volvo IPS or Cummins systems are also available for those prioritizing performance.
Efficiency Metrics
Lightweight construction and sleek hull geometry translate to better fuel economy and extended range. The MC63, for example, achieves remarkable efficiency at cruising speeds—requiring significantly less fuel than comparable monohulls.
Acoustic Engineering
Beyond performance and economy, McConaghy designs with comfort in mind. The carbon hulls are acoustically engineered to minimize vibration and sound propagation throughout the yacht, creating a quiet onboard atmosphere whether anchored or underway.
