This 2020 Lagoon 46 is a three-cabin owner's version catamaran built on a fiberglass hull. Twin 114 hp Yanmar diesel engines power the boat, which spans 45 feet in length and 26.8 feet across the beam. The three-cabin layout dedicates the entire starboard hull to a full-beam owner's suite with desk and sofa, while the port hull houses two guest cabins. All three cabins include private heads. The boat features multi-zone reverse cycle air conditioning throughout the salon and sleeping areas.
The salon and galley open to the cockpit via panoramic windows, creating a unified indoor-outdoor living space. A flybridge helm station overlooks the water and includes lounge seating. The expansive cockpit features a dining table and refrigeration, while forward a signature Lagoon foredeck lounge offers additional seating and sunbathing. Twin aft swim platforms provide easy water access, and the interior includes substantial storage for extended cruising.
Recent 2024 upgrades represent over $49,000 in work. The electronics suite includes new Garmin Zeus plotters with autopilot, AIS, and radar mirrored at both the helm and nav station. Power independence comes from a 2,200-watt solar array, 2,400 amp-hour lithium battery bank, and Onan 13.5 kW generator. The electrical system received a complete overhaul with new Victron Cerbo GX unit and inverter. Three new Dometic air conditioning units were installed, and complete new upholstery and cushions were fitted throughout. The hull received a protective PPE wrap with new graphics, new bottom paint, and underwater lighting. Both Yanjem engines underwent full service, along with the generator, sail drives, and rigging.
Spring 2025 brought replacement of the flybridge enclosure and installation of a custom lazy bag. The solar charger controller was replaced in late 2025, and the generator battery and bilge float switch were serviced. All maintenance records are available. The boat has never been chartered and was maintained as a private owner's vessel.
