Americas Cup Pedigree Yacht.

The McConaghy 55 Multihull was designed from the ground up by Jason Ker and his team highly experienced sailors, engineers and designers at Ker Yacht Design & Engineering. Jason has been heavily involved in multiple Americas Cups including the most recent edition in catamarans. The builder, Mark Evans and his team at McConaghy Boats are responsible for some of the most high tech racing machines and luxury superyachts in the world built for some of the most demanding customers and conditions.

Overview of the McConaghy 55 multihull

The MC55 (formerly known as the MC52) has many improvements over the older model. The boat now has a larger cockpit with outside lounge seating as well as a forward cockpit which is accessible via the main salon. She sails close to windspeed, which means she can approach cruising speeds which are very close to the True Wind. Thanks to a meticulous control of weight owner’s will experience sailing unlike on any other catamaran. Sailing in utmost luxury at double digit speeds, effortlessly and safely.

Unlike many other high-performance catamarans – the MC55 has been designed and engineered with safety as its core parameter. Potentially hazardous daggerboards which could create a hull breach have been avoided and replaced by a simple but highly effective push-button centerboard system – a first in this luxury multihull market segment. In the retracted position the centerboard is completely flush with the hull, yet full deployed a high aspect draft of nearly 9’ rivals the most efficient windward foils. In case of striking an underwater object, the centerboards will automatically raise and avoid damage to the hull structure. Thanks to her specially controlled vacuum infusion process of pressed panels of E-glass/Epoxy, carbon-hybrid composite foam construction the McConaghy 55 multihull is much lighter than similar length catamarans, yet she is luxurious, safe and immensely stiff. Like the last generation of America’s Cup foiling catamarans which are so strong and light that they do not need a fwd. crossbeam, the McConaghy 55’s stiffness and full carbon longeron also allow for this elimination of the forward crossbeam, which further lightens this amazing yacht.

Performance Sailing to the Next Level

The McConaghy 55 multihull is a true luxury Grand Prix style yacht and has a multitude of innovative features, such as a completely opening, all glass aft salon doors and giant sliding side salon windows. This means that most of the time, even in pouring rain you can enjoy an “open” platform with full protection from the elements. The MC55 is also the only high-speed catamaran with a highly efficient flybridge, which provides not only a perfect social gathering space, but also lets the helmsman fully control this thoroughbred from one single control station.

Interior Design to match the MC55 Performance

Of course, the interior of the MC55 is top class and only the finest woods and hardware are used throughout. All joinery is custom built and finished to McConaghy Boats uncompromising high-quality standards under the expert guidance of the interior design team of Design Unlimited. The modern 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.

Detailed Engineering like no other Multihull

From the advanced DC-switching system which you can control from your I-pad to the four standard electric radial winches on the flybridge the MC55 is a push button, no-compromise yacht. The McConaghy 55 catamaran is built in the same production facility, by the same passionate craftsmen using the techniques employed on the worlds most advanced super-maxis and hardcore racing yachts. This means the attention to weight control (the enemy of fast cats), detail and engineering is like in no other yard. This performance cruising catamaran is the perfect blend of luxury and high tech. Think next-gen fighter jet meets a New York style luxury loft apartment.
