The McConaghy MC75 JACK is light weight, eco-friendly luxury performance cruising catamaran. The progressive design features an appealing flybridge extending aft which creates a sweeping, sleek look.

Performing with an effortless grace even in light airs, the McConaghy MC75 JACK provides smooth sailing prowess with stability and enviable speed. Weighing half the weight of many of her contemporaries she can sail in sub 10 knots however, in 20kts of wind with a code zero flying the MC75 can reach 21knots of boat speed.

The McConaghy MC75 JACK features a large saloon lounge with a dining area and walk-around bar, a spacious aft deck with sofas and al fresco dining space, and cushioned foredeck area. The sophisticated environment offers a fantastic visual connection with the sea. Fully retractable sliding side windows and floor-to-ceiling glass create the perception of freedom, with an infinite amount of visual space and an enhanced, symbiotic relationship between inside and out. Within, internal volume has been maximised and every space configured with a distinct purpose in a layout that dispels all preconceptions of yacht interiors.
