Sailing maxi catamarans are large multihull sailing yachts, typically 60 feet and above, used for private cruising, long-distance passage-making, and luxury charter. The twin-hull configuration provides beam, stability, and interior volume that comparable monohulls cannot match at the same length.
The wide platform allows for expansive saloon layouts, multiple cockpit zones, flybridge levels on larger builds, and en-suite cabin arrangements in each hull. Stability at rest and under sail is a significant advantage for guests unaccustomed to monohull heel angles. The trade-off is marina access: beam commonly exceeds 10 metres on 60-foot-plus cats, requiring catamaran-friendly berths and attracting higher harbour fees. Downwind sailing performance is strong; windward efficiency is lower than comparable monohulls.
Hull construction is typically fibreglass or carbon composite, with foam or Nomex core sandwich panels used on performance-oriented builds. Daggerboards are specified on cruising-racing designs to improve upwind performance. Auxiliary propulsion consists of twin diesel engines — one per hull — which also provide excellent manoeuvrability under power. Charter-optimised maxi cats typically carry four to six double cabins; owner-focused builds may sacrifice guest capacity for owner suite volume and crew quarters.
