Lagoon 420 Catamaran “IrieMystic”.
Exceptionally maintained, turnkey cruising catamaran.
“IrieMystic” is a beautifully maintained Lagoon 420 cruising catamaran that has been meticulously cared for by a conscientious private owner. The vessel has never been chartered and has benefited from an exceptional maintenance routine including weekly washes and professional waxing every quarter, keeping the hulls and topsides in outstanding cosmetic condition.
Designed by the renowned naval architects VPLP and built by Lagoon in France, the Lagoon 420 is widely respected for its stability, expansive beam, and comfortable offshore cruising capability. With her wide beam and spacious layout, this catamaran offers exceptional living space, panoramic salon views, and safe, stable sailing performance.
Powered by twin diesel engines, IrieMystic delivers strong performance under power and excellent maneuverability when docking. The engines have been consistently serviced and maintained, ensuring reliability for coastal cruising or extended offshore passages. An onboard generator provides power for the vessel’s systems and house loads.
The sailing setup is capable and easy to manage. The sail plan and deck layout allow sails to be handled easily from the cockpit, making the boat comfortable to operate even with a small crew.
Below deck, the Lagoon 420 provides an exceptionally comfortable interior that rivals much larger yachts. The salon is bright and airy with large panoramic windows and a spacious seating area ideal for relaxing or entertaining. The galley is well equipped for cruising, and additional onboard comforts include laundry facilities and ample hot water.
The owner’s suite has been upgraded with a custom oversized master berth that provides enhanced comfort compared to the standard layout. Air conditioning throughout the vessel ensures comfortable temperatures in all cabins and living spaces.
For extended cruising independence, the boat is equipped with a watermaker and a robust electrical system with solar charging, battery banks, an inverter, and shore power capability.
Navigation electronics include chartplotter, radar, autopilot, depth and speed instruments, and communications equipment, providing reliable navigation and connectivity whether cruising the coast or island hopping.
The cockpit area is spacious and well designed for outdoor living, with a dining area, shade protection, and easy access to the swim platforms. Some additional recent upgrades include new Highfield 310cl tender with 20 hp yamaha, New North Sail Jib, New bottom Paint and Sail drive service.
