2004–2010 · designed by Marc Van Peteghem and Vincent Lauriot-Prévost (VPLP) · built by Lagoon / Construction Navale Bordeaux
Production cruising catamaran whose raised flybridge helm and forward cockpit separate sailing and social spaces. The design offers substantial accommodation, but the buyer should trial communication, movement and visibility between helm and cockpit with the intended crew.
Check this first — The 2006 owner's manual documents different mast and sail arrangements. Identify the installed rig, layout and optional machinery before applying air-draft or load figures. This guide covers the 2004–2010 generation preceding the 450; the exact last 440 hull date is not established here, so check HIN and build documentation on boundary-year listings.
This is a general read on the Lagoon 440 class — informed background, not a verdict on any individual boat. Condition, refit history, and how a particular hull was sailed and stored matter far more than class reputation. Use it to know what to look for; for a read on a specific listing, run a free FairKeel report on that boat.

Trial communication between helm and cockpit, safe movement and visibility. Ask the rigger to examine control leads and attachments, including any altered bimini or enclosure.
Have both steering paths, rudder-stock interfaces and play checked. Demonstrate the emergency tiller and identify any furniture or storage obstructing access.
Request each engine and drive's identification, service history and loaded test. Confirm the fitted machinery rather than interpreting the manual's maximum permitted power as actual engine output.
Ask the surveyor to trace water paths, previous flooding evidence and changes to compartments. Test pumps and isolation points in both hulls.
Reconcile the builder plate, manuals and later equipment list. Check installation quality and carrying capacity before accepting a fully equipped description as a benefit.
This guide is the class. A report is that hull. Paste the listing you're looking at and FairKeel grades every claim in it against what's known about the Lagoon 440 — where the evidence is thin, the red flags worth a second look, the costs likely to land in your first season, and whether the boat suits the plans you describe in a few short questions.
It won't read the photos or put a number on the boat — that's the $249 Deep-Dive, and for the real answer, a surveyor. It will tell you when a Deep-Dive isn't worth buying. Free, no account, usually a minute or two.
