2026 McConaghy MC100

The McConaghy MC100 is a 100-foot catamaran built for extended cruising with genuine sailing capability combined with superyacht-level comfort. At 40 feet of beam, the design delivers substantial interior volume and social spaces while maintaining the performance characteristics the MC line is known for.

The layout includes five cabins, providing accommodation for family and guests. The catamaran hull form offers shallow draft and fuel efficiency, powered by twin diesel engines. The design philosophy balances active sailing performance with the refinement and amenities expected in larger yachts, avoiding the compromises often found in comparable monohulls.

This is a new build from McConaghy, built to the exacting standards of their multihull program. The MC100 represents the upper tier of the MC series, scaled to offer considerably more space and entertaining areas than smaller models while retaining the seaworthiness and efficiency that define the brand.
