Lagoon 421 Owner Version – 2010 | Air Conditioning | Generator | Watermaker | One Owner
This Lagoon 421 Owner Version represents an excellent opportunity to acquire one of Lagoon's most successful cruising catamarans, designed for comfortable long-distance cruising and liveaboard living.
Built in 2010, commissioned in January 2011, privately owned since new by the same owner, this sought-after 3-cabin/3-head owner's layout offers significantly more comfort, storage, and privacy than the more common charter configurations.
The yacht is exceptionally well-equipped for extended cruising, featuring air conditioning, heating, a generator, a watermaker, electric winches, AIS, radar, and upgraded electronics. The spacious saloon, large galley and generous owner's accommodation make her ideal for couples, families or liveaboard sailors looking for a capable and comfortable cruising platform.
The Lagoon 421 remains highly regarded for her outstanding balance of interior volume, seaworthiness and ease of handling. Wide side decks, a protected cockpit and excellent visibility from the helm contribute to safe and enjoyable cruising in a wide variety of conditions.

Accommodations
With an approximate length of 12.61 meters, the Lagoon 421 offers an optimised layout with 3 double cabins and 3 bathrooms, providing privacy and comfort for both family use and extended cruising trips. Its interior configuration maximises natural light through large panoramic windows, creating a sense of spaciousness that is superior to what is typical for its class. Each cabin has its own bathroom, guaranteeing comfort at all times.
Its interior layout offers a practical kitchen, a bright living room with panoramic views and multiple indoor and outdoor relaxation areas.
Thanks to its generator, air conditioning and water maker, the Lagoon 421 is prepared for long stays at sea with maximum comfort.
Equipment
Onboard comfort: ONAN 11KVA generator, 44,000 BTU air conditioning, desalinator, ice maker, and inverter.
Nav Equipment: Raymarine E-12W Display advanced electronics, 48MN Radar, 4KW Radome, remote-controlled autopilot, AIS 250, VHF 55E USA and steering joystick.
Electric winch for davits and easy access to the sea.
Sails and Sail Handling: Mainsail, spinnaker and furling genoa, complemented by an electric winch system that makes sail handling easy and efficient, enhancing comfort and reducing effort while sailing.
Raymarine internal helm joystick installed at the chart table (currently not operational and requiring diagnosis).
The yacht was originally built for the US market and therefore features 110V domestic outlets and American-style sockets. She is, however, currently operating in Europe and is connected to 220V shore power via a transformer/converter system. The arrangement works correctly, although buyers should be aware that replacing domestic appliances and converting the vessel entirely to European specification may require additional investment if desired.

Great Service, Great People
Helped me through the process.
I would go through them again in a future purchase.
The Multihull Company made the process of buying our boat easy and predictable. Both our agent (Francisco Montaner) and Andrew Holland communicated well and educated/informed us of each step in the process. I highly recommend The Multihull Company for those shopping for a catamaran!
Chuck at The Multihull Company is the real deal.
He helped us find our Lagoon 40 after genuinely listening to what we needed, not just what he had to sell. He let us visit the boat multiple times, answered every question honestly, and helped us make a confident decision on a major purchase.
What impressed us most was the post-sale support. Once the paperwork was signed, Chuck was still picking up the phone, offering referrals, and helping us work through the early stages of liveaboard life. That kind of follow-through is rare.
If you are looking for a multihull and want someone who knows the boats and actually cares about the outcome, Chuck is the person to call.
We just purchased a 2025 Nautitech 44 Open with The Multihull Company. The process of getting here has been great, and we could not have asked for a better agent. We worked with Conor, whom we met at the 2025 Cannes Boat Show. We started our search for a cruising catamaran in Florida at the beginning of the year. We spent a couple of months looking at different boats/models within our price range and quickly narrowed it down to what really mattered to us, in part thanks to the wealth of knowledge and expertise our broker provided. When we found a perfect match in Montenegro, Conor and The Multihull Company did not hesitate to continue supporting us and to lead the efforts from start to finish with great care and transparency. Communication and support have been outstanding throughout this entire process. Conor, in particular, showed great compassion and care, going above and beyond to ensure that no stone was left unturned and that we would be able to safely and happily sail off into our big adventure.
A sale well handled. No inflated expectations and an honest opinion throughout. Highly recommended.
Successful relationships cannot exist without it. At The Multihull Company we base every relationship on a firm commitment to earning and retaining our client’s trust.
Advice of any kind is valuable only when grounded in hard-won expertise. It too, must be trustworthy. Trust and expertise define the heart and soul of The Multihull Company. We are a team of skilled professionals who thrive on providing expert, trustworthy advice and service to catamaran and trimaran sailors around the globe.
