LAGOON 421

Remarks :

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 and 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.
