Full Carbon. Optimal Performance.
The MC55 performance catamaran might be the smallest multihull in the MC Multihull range, but this cat is no kitten. The MC55 not only benefits from McConaghy’s vast experience building performance boats but also from a carefully considered use of carbon, that sees her precise hull forms achieve an optimum strength to weight ratio.
Key Highlights
Full Carbon Construction
Vacuum infused carbon hull, deck and structure built with Carbon and Corecell panels for exceptional lightweight strength and rigidity.
Hydraulic Centreboards
Two articulating composite centreboards, hydraulically deployed with three preset positions, adjustable from 1.3m retracted to 3.7m fully deployed.
Integrated Solar & 50kWh Battery
4.5kW solar panels integrated into the coachroof, paired with a 50kWh battery system and full Victron energy management.
Mc1 Spars Mast & Rigging
Carbon fibre mast and V-boom with 150m² upwind sail area. Square top mainsail and self-tacking furling jib, both in North Sails 3Di OCEAN 700.
Complete Navigation Suite
Dual 12" touchscreen chartplotters, dome radar, GPS, VHF and Madintech autopilot - a complete navigation package fitted as standard.
The full carbon MC55 redefines the cruising experience by bringing the helm indoors. With twin internal helm stations, you can command in absolute comfort, remaining completely shielded from the weather while maintaining superior visibility for difficult in-port manoeuvres. Designed for ease of use, her integrated push-button short-handed sailing capabilities make her remarkably simple to handle, even for those new to the world of multihulls.
There are two accommodation layouts to choose from; a four-cabin layout (all en suite) or a three-cabin layout, which allows for a large master suite, complete with private study, in the starboard hull.
The wide saloon offers a versatile and spacious living area that, with large windows running the full length of the hulls and fully retractable glass doors to aft, is exceptionally light and provides fantastic views. The galley is arranged open-plan to this area, which creates an apartment-like feel and is particularly well suited to socialising and family living.
Exterior
The MC55 makes an immediate impression with its full carbon hull and deck, finished in high-gloss two-pack polyurethane and built for both speed and endurance. The expansive aft deck features port and starboard settees, an electric barbecue, wet bar and hydraulic swim platform, while the forward cockpit offers a sheltered second social space. Integrated 4.5kW solar panels sit flush in the coachroof, and hydraulic centreboards retract cleanly into the hull for uncluttered performance at every point of sail.
Interior
Step inside and the MC55 delivers a level of finish rarely seen in performance multihulls. Honeycomb-core joinery panels, lightweight timber laminate and soft fabric liners create a refined, modern feel throughout. The galley centres around a generous island with Corian type countertops and twin 160L Isotherm fridge and freezer drawers, while twin forward helm stations keep the crew connected to the action. The starboard hull is dedicated to the owner’s stateroom, with a private lounge, dressing room and ensuite, and the port hull offers two additional guest cabins with their own bathroom.
