About the Lagoon 421

At 12.61 m the Lagoon 421 offers the space many owners want for long-term cruising or living aboard, while still being manageable by an experienced couple. With a beam of 7.7 m she is very wide for her length (61 %), which gives a stable platform and a lot of interior volume – but check marina berth widths before you buy.

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 421

• Standing rigging older than about ten years is often questioned by insurers – check its age.
• Ask when the saildrive seals were last replaced and check the engines’ service history.
• 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.
