The world feels very far away aboard JACK. No deadlines. No noise. No compromise. Just horizon, silence, and the unmistakable feeling that life is finally being lived properly.

The McConaghy MC75 JACK is not simply another luxury catamaran. She is a rare collision of superyacht comfort, advanced carbon engineering, and genuine offshore performance. Built entirely in carbon composite by McConaghy Boats and designed by the renowned Ker Yacht Design studio, JACK delivers something very few yachts ever achieve: breathtaking speed without sacrificing absolute refinement. This is the kind of yacht that changes plans. The kind that convinces owners of large motor yachts to reconsider everything they thought they wanted from life on the water.

At anchor, JACK feels like a private waterfront penthouse suspended above crystal-clear water. Expansive glazing, retractable side windows, and a beautifully restrained interior create an atmosphere that is calm, architectural, and effortlessly luxurious. Every space has been designed to connect you with the ocean, not separate you from it. Under sail, she becomes something else entirely. Lightweight carbon construction, hydraulic centreboards, and race-bred hull design allow JACK to move with extraordinary efficiency and composure. She is capable of exceeding 21 knots under sail while remaining remarkably stable, quiet, and comfortable for guests onboard. Her pedigree is not theoretical either. JACK claimed both Line Honours and Multihull Class victory in the 2024 ARC Transatlantic, covering over 3,100 nautical miles with speed and ease.

Yet perhaps the most impressive thing about JACK is not the performance. It is the freedom. The freedom to disappear into the islands for months at a time. To wake up in complete silence powered by solar energy and advanced 48V onboard systems. To entertain family and friends in total comfort without marinas, crowds, or schedules dictating the experience. This is luxury without excess. Performance without aggression. Adventure without hardship.

For the buyer who has already experienced the predictable world of conventional yachting, JACK offers something far more compelling.
- A complete escape.
- A new pace of life.
- And the ability to simply cast off and leave the rest behind.
