Overview - MC50 Globally Impressive

Powerful yet easy to manage under sail, the MC55 is the latest addition to the McConaghy Multihulls range. An extremely luxurious finish comes as standard and enhancements to the aft deck give a larger area for socializing, space for watersports toys and additional systems.

The MC55 not only benefits from McConaghy’s vast experience building performance boats but also from a carefully considered use of carbon, that sees her precise hull forms achieve an optimum strength to weight ratio.

Interior - Your apartment on the water

There are two accommodation layouts to choose from; a four-cabin layout (all en suite) or a three-cabin layout, which allows for a large master suite, complete with private study, in the starboard hull.

The wide saloon offers a versatile and spacious living area that, with large windows running the full length of the hulls and fully retractable glass doors to aft, is exceptionally light and provides fantastic views. The galley is arranged open-plan to this area, which creates an apartment-like feel and is particularly well suited to socialising and family living.

The MC55’s interior styling comes from Design Unlimited, an award-winning studio with extensive experience in both large custom yachts and the production sector. Their attention to detail and innovative storage solutions allow living space to be maximised, with the client able to choose from an array of customisable options and a choice of three main interior colour schemes.

Exterior - Speed, Safety and Comfort

As with all McConaghy Multihulls, the MC55 has dual helm positions on the flybridge, allowing for the greatest sightlines forward as well as an elevated position that aids more difficult in-port manoeuvres – making her an ideal choice for those new to multihull cruising.

Descend the stairway from the flybridge to a spacious cockpit with plenty of seating and sun lounging space for rest and relaxation. Select the optional hydraulic swim platform and create your own private terrace with easy access to the water for swimming and water sports.
