Lagoon 500 Buyer's Guide
Shopping the brokerage market for a Lagoon 500 means considering a 51-foot third-generation Lagoon catamaran built between 2005 and 2012, a flybridge cruiser conceived for private ownership or charter. These boats carry a 28-foot beam, twin fixed keels drawing 4 feet 7 inches, and a light displacement near 38,800 pounds, with 254 gallons each of fuel and water. The used fleet splits between charter four-cabin layouts and owner-oriented plans, and ex-charter examples are common on the market.
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 charter version places a small crew cabin in the starboard hull opposite the pantry while keeping four guest staterooms with private heads, whereas the owner's versions devote the starboard hull to a single large stateroom or a forward cabin plus expanded owner's suite. All plans keep the galley up and stepped down, a port-hull pantry, and a sheltered aft cockpit separated from the flying bridge by three hatches.
Equipment and Common Upgrades
Well-equipped examples commonly carry solar, autopilot, chartplotter, radar, air conditioning, inverter, watermaker, electric winches, and a bimini, forming the core power, navigation, and comfort package most buyers should expect. Often-seen additions include lithium batteries, AIS, Starlink, a freezer, washing machine, and a life raft, which extend off-grid endurance and safety. Less common owner upgrades run toward a furling main, asymmetric spinnaker, dinghy davits, and teak decks. For a cruising buyer, the consequential clusters are energy (solar, lithium, inverter, generator in the bridgedeck) and sail handling (electric primaries, furling main), since they determine whether the boat is ready for independent voyaging without immediate refit spend.
What to Inspect
From the elevated flying bridge, it was impossible to see rapidly approaching hazards behind the jib, so confirm the genoa carries its clear viewing window and that the helm sightlines are acceptable for your waters. The 500 runs afoul of United States standards regarding propane storage because the propane locker is inside a larger compartment, so inspect how the locker is integrated and vented before committing to a United States berth. Check the gas-spring assisted cockpit seat access to the aft electrical panel and the transom-step hatches to the isolated engine compartments for smooth operation, and verify the generator space forward of the mast is reachable and dry.
Availability and Buyer's Takeaway
Typical markets for the Lagoon 500 are France, the United States, Greece, Thailand, Martinique, and Spain. For a buyer, the practical checklist is: confirm layout (charter vs. owner) matches intended use; verify electric winches and sail-handling upgrades are present; inspect propane locker compliance and bridge sightlines; test generator and electrical panel access; and weigh ex-charter wear against owner-version privacy.
