MC90 Cat: McConaghy’s New Sailing Catamaran Series

McConaghy Boats, the builder behind the daring trimaran Adastra and a number of performance sailboats, plans to unveil a high-performance cruising-catamaran series this weekend at the Boot Düsseldorf show. Comprised of three models so far, it has the above-featured MC90 Cat as its largest offering.

The series was conceived with Ker Yacht Design, a previous collaborator. The studio is additionally adept at multi-hull design. Jason Ker, principal of the company, was part of teams penning the design of America’s Cup racers within the past decade.

Multi-hulls are also often praised for their stability, comfort, and low draft, plus room. The MC90 Cat is aimed at buyers who understand these advantages, particularly ones already familiar with catamarans. More specifically, McConaghy states the ideal client is a “performance-oriented keel boat owner looking for added comfort and volume—and a desire for speed!”


Neither McConaghy nor Ker Yacht Design have revealed anticipated performance figures at this juncture. Though, the 4,768-square-foot (443-square-meter) upwind sail area for the MC90 Cat should get people’s attention. So, too, should the basic specifications. The MC90 Cat measures 89’9” (27.4 meters), with an impressive 88’6” (27 meters) of waterline length. The sailing superyacht’s draft will range from just shy of 4 feet to 16’4” (1.2 to 5 meters), too.

As for volume, the MC90 Cat should deliver in spades. Consider that interior headroom is 6’9” (2.1 meters), with beam being a more-than-healthy 40’4” (12.3 meters). Consider, too, that the MC90 Cat has an open-plan arrangement. The seating and dining areas in the cockpit flow easily into the interior relaxation zone. The interior flows outside once again forward, into an ultimate seating area with a view, adjacent to the trampoline.
