2027 McConaghy Boats MC75

Experience the MC75: Effortless Elegance on the Water

McConaghy MC75 Catamaran - Semi-Custom 

(Power CAT Also Available)

Sail with unparalleled grace, even in light winds, aboard the MC75, where stability meets remarkable speed. In 20 knots of wind at a 110-degree true wind angle, the MC75 can achieve an impressive 21 knots with a code zero sail, ensuring smooth sailing in any condition.

Step inside the MC75 to discover an interior that exudes an apartment-like ambiance, beautifully designed with an architectural flair. This sophisticated space offers breathtaking views of the sea, thoughtfully incorporating all essential amenities in a way that is both aesthetic and functional.

The fully retractable windows and floor-to-ceiling glass enhance the sense of freedom, creating a seamless connection between the interior and the great outdoors. Every corner of the MC75 has been designed with intent, maximizing internal volume and redefining yacht interiors.

The open-plan layout can be customized to reflect your unique style, with bespoke furnishings that prioritize convenience, versatility, and designer aesthetics. 

Enjoy the expansive saloon lounge, featuring a dining area and walk-around bar, or relax on the spacious aft deck with comfortable sofas and al fresco dining options. For sun-seekers, cushioned sun pads await you forward of the superstructure. The MC75 accommodates five luxurious seaward-facing en suite berths, along with a crew cabin conveniently located next to the galley in the port hull.

Set sail in style and comfort with the MC75, where every journey becomes a memorable experience.
