Yacht description

Amazing, fast catamaran designed by Jason Ker

The MC50 might be the smallest multihull in the McConaghy range, but this cat is no kitten.  The MC50 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.  

As with all McConaghy Multihulls, the MC50 has dual helm positions on the flybridge, allowing for the greatest sight lines 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.

There are two accommodation arrangements offered as standard; 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. This specific MC 50 is a 3 cabin version.

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 MC50’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.

The boat is fully loaded with systems:

  • 100% Carbon rig from Axxon
  • B&G navigation with helmet screens.
  • A/C cold/hot.
