Lagoon 400 Buyer's Guide
The Lagoon 400 entered production in 2009 as Lagoon's third-generation cruising catamaran, and a healthy number were sold, with ex-charter examples common on today's brokerage market. For a shopper, the boat presents as a high-volume liveaboard multihull whose comfort and maneuverability outweigh outright sailing performance, and the used fleet reflects that original brief.
Layouts on the Used Market
Charter four-cabin layouts are the more common on the used market, but both three- and four-cabin versions are available. The three-cabin arrangement trades berths for an enormous owner's suite with office and bath, while the four-cabin plan suits charter or family use. Ex-charter examples are common, so buyers should expect higher cycle counts on systems and interiors than a privately owned boat.
Equipment and Common Upgrades
Power and energy systems are where the used 400 fleet is best equipped: chartplotters, solar, inverters, and watermakers are commonly fitted, while lithium batteries, electric winches, and sometimes a generator support extended off-grid stays. Navigation and safety often include autopilot, AIS, radar, and life raft, with dinghy davits and cockpit showers frequently seen. Comfort upgrades such as air conditioning, heating, and freezers appear often, and a few boats carry a code zero or asymmetric spinnaker as owner additions rather than standard kit.
What to Inspect
The sliding door and window latch between saloon and cockpit drew criticism from Cruising World's Boat of the Year judges for being hard to operate, so work it repeatedly at survey. The same judges worried the saloon electrical panel could be reached by children, worth verifying if traveling with family. The significant windage with beam wind in harbor is a real handling factor, so observe the boat under engine with a crosswind if possible. The lack of a step onto the cabin top is a design limitation for mast-access tasks; confirm crew can manage main pouch zipping safely.
Availability and Buyer's Takeaway
The Lagoon 400 regularly appears in the United States, Croatia, Greece, France, Italy, and Malaysia. For a buyer, the checklist is straightforward: confirm layout matches intended use, verify the commonly fitted energy and watermaking gear functions, exercise the saloon latch and electrical panel access, and budget for windage-aware docking practice.
- Choose three- or four-cabin layout by liveaboard vs charter need
- Test saloon door latch and check electrical panel security
- Confirm solar, inverter, watermaker, and autopilot operational
- Plan for beam-wind harbor handling due to tall topsides
