MCCONAGHY UNVEILS LUXURIOUS MC115 MULTIHULL YACHT

The McConaghy MC115 is a 35-meter flagship catamaran from Australian builder McConaghy Boats, designed to close the gap between the production multihull market and the superyacht sector through an enclosed flybridge, a six-stateroom layout and advanced composite construction.

What is the McConaghy MC115?

McConaghy has competed in high-performance racing and production boat categories for decades, and the MC115 is the largest model in its MC Multihulls range. At 115 feet, it is sized for serious offshore cruising and charter use, but its design priorities are comfort and usability rather than pure speed. The enclosed flybridge is the defining architectural move: positioned directly under the mast, it provides an all-weather helm station and commanding views while freeing the main deck for social space.

Layout and accommodation

The MC115 accommodates two owners and up to 10 guests across six ensuite staterooms. The master suite is placed forward of the saloon and connects directly to a private exterior lounge and a Jacuzzi on the foredeck. The galley is positioned below deck to keep the main deck entirely dedicated to living and social space, a superyacht-influenced decision that significantly improves the onboard experience. A hydraulic beach club platform at the stern and an extensive aft deck add further usable outdoor area. Separate crew accommodation for four keeps owner and crew circulation independent.

Performance and construction

The MC115 is built using advanced composite materials throughout, keeping displacement low and structural rigidity high. With a true wind speed of 20 knots at 100 degrees apparent, the yacht is capable of 21 knots, figures that are strong for a vessel of this size and purpose. Twin 370 hp inboards handle motoring passages. The hull beam of 41 feet delivers the stability typical of a cat platform while providing generous interior volume across both hulls and the bridge deck.

The case for a multihull flagship

The MC115 addresses a genuine gap in the market. Multihulls of this size with superyacht-grade interiors and an enclosed flybridge are rare, and McConaghy's racing heritage means the structural engineering is unusually rigorous for a cruising boat.
