Thanks to McConaghy’s highly efficient production facilities the MC90 can be built in less than 18 months. Her specially controlled vacuum infusion process of E-glass/Epoxy, carbon-hybrid composite foam makes her much lighter than similar length catamarans. Consequently she is strong, safe and immensely stiff. The MC90 will sail at windspeed in light airs. Similar to the last generation of America’s Cup foiling catamarans, the McConaghy 90’s rigidity and full carbon longeron also allow for the elimination of the forward crossbeam, which further lightens this amazing yacht.

Sailing Sensations like a true Thoroughbred Yacht

The McConaghy 90 multihull, like high performance racing yachts, is helmed via twin pedestal steering stations positioned well aft. The elimination of the flybridge further reduces aerodynamic efficiency and weight – and at the same time lowers the stunning profile of this Grand Prix yacht. Expansive glass panels in the hulls and saloon slide open to create an inside/outside living space. The spacious forward cockpit is another key lifestyle defining feature of the MC90.

Stunning Interior with Unlimited Options

Of course, the interior of the MC90 multihull is top class. Consequently the builder only utilizes the finest woods and hardware. McConaghy Boats custom builds every piece of furniture to uncompromising quality standards to the stylish interior design team of Design Unlimited. The timeless interior is constructed using a mix of hand-painted surfaces and lightweight, exotic wood laminates with soft fabric accents. There are a variety of layouts to choose from.

The McConaghy 90 multihull was born from the drawing board of illustrious naval architect Jason Ker. His name is associated with high performance racing yachts and the BAR Racing – British America’s Cup catamaran.
