About the Lagoon 51

At 15.6 m the Lagoon 51 is a large cruising catamaran with room for guests and extended voyages. Boats of this size often have electric winches and more systems aboard. Her beam of 8.1 m is typical for a cruising catamaran of this length.

Lagoon is a French builder and part of Groupe Beneteau. It is the world’s best-selling catamaran brand, and most of its sailing models are designed by VPLP. Because Lagoons are a staple of charter fleets, there is a large choice of used boats.

Buying a used Lagoon 51

• As a current model she can be ordered new; demo boats and nearly-new boats with remaining warranty are worth looking for.
• Inspect both hulls, keels and rudders for grounding damage and check the bridgedeck for cracks.
• Many Lagoon boats come out of charter fleets. Ask for the full maintenance log and read our guide Ex-charter or owner’s version?.
• Always commission an independent survey with a haul-out – see our buying checklist.
