Lagoon – 400 S2

Florida, United States

Owner’s version, Low Hours, No Storm Damage, Never Chartered, Water Maker, ICW friendly mast

The 400 was first launched by Groupe Beneteau’s Lagoon brand in 2009. The Lagoon 400 was an overnight success with the perfect blend of liveaboard space, storage, comfort, easy to maneuver, and reasonably well sailing boat. From 2012 until 2017 Lagoon built what they called the “S2” version of the 400, which included an interior redesign by Nauta Design.

Since the end of the production run in 2017 the Lagoon 400 S2 has remained in high demand in the catamaran brokerage world, and the 2017 Lagoon 400 S2 Freebird is an excellent example of what happens when an experienced owner takes a lightly used Lagoon 400 S2 and further improves upon it.
