Lagoon 500 Buyer's Guide
The Lagoon 500 is a 51-foot cruising catamaran from the third generation of the marque, conceived for luxury ocean cruising in either private-ownership or charter service. On the brokerage market used Lagoon 500s present as a luxury ocean cruiser, and the documented layouts and known issues below should frame any inspection.
Layouts on the Used Market
Charter four-cabin layouts are the more common on the used market, but both are available; ex-charter examples are common. The builder offered three interior arrangements: the charter version mirrors the port hull's two staterooms with private heads in the starboard hull but adds a small crew cabin opposite the pantry, while the owner's version with skipper keeps a forward cabin and devotes the rest of the starboard hull to a larger stateroom, and the plain owner's version gives the owner the entire starboard hull. In every layout the port hull holds a forward and aft stateroom each with a private head plus the pantry, the galley is up but stepped down to meet seated head height, and a nav station with duplicate engine controls sits to starboard.
Equipment and Common Upgrades
Solar, bimini, autopilot, chartplotter, air conditioning, inverter, watermaker, and radar are commonly fitted. Often-seen additions include lithium batteries, electric winches, AIS, Starlink, freezer, washing machine, and life raft. Less commonly seen are cockpit shower, swim platform, asymmetric spinnaker, furling main, hot water, dinghy davits, teak decks, heating, gennaker, and hardtop. The boat as reviewed carried no bimini over the flybridge, only a spray dodger, though the builder states a bimini with windshield was standard, and the builder's dealers recommended the electric option for primary winches and the mainsheet/traveler winch.
What to Inspect
The most safety-relevant documented issue is the U.S. standards conflict on propane storage, where the propane locker is inside a larger compartment. The builder describes the bottles as stored in a ventilated, sealed, and waterproof locker with a ventilation drain running directly out to under the bridgedeck, but the as-installed arrangement still runs afoul of U.S. standards propane locker is inside a larger compartment. Also verify the flying-bridge sightlines: from the elevated bridge it was impossible to see rapidly approaching hazards behind the jib, with the genoa clear window as the only sightline aid. Check the main electrical panel on the aft bulkhead in the saloon and confirm the aft-facing cockpit seat hinges up on gas springs for access, and inspect the separate engine compartments entered via hatches at the top of the transom steps.
Availability and Buyer's Takeaway
Typical markets are France, United States, Greece, Thailand, Martinique, and Virgin Islands, U.S. A used Lagoon 500 should be checked for: charter versus owner layout and condition from ex-charter service; propane locker compliance with U.S. standards if intended for U.S. use; flying-bridge blind spot behind the jib and genoa window integrity; electric winch and bimini standard fitment versus advertised; and hull payload and machinery-space access via sunning cockpit and transom-step hatches.
