Lagoon 400 S2

After seeing over 260 boats built in three years, the Lagoon 400 (launched in 2009) has found a new lease of life through Nauta Design’s work on the boat’s interior fittings. Suggestions received from owners have enabled Lagoon to produce a boat that is even more welcoming, with a greater level of comfort, and resolutely modern: the result is the Lagoon 400 S2, a nod to its famous predecessors, the Lagoon 410 S2 and 380 S2.

Like its predecessors, the Lagoon 400 S2 is designed for coastal or ocean cruises. It can comfortably accommodate 8 with its 3 or 4 double cabins, elegantly fitted, spacious interior, and her cockpit and salon on the same level.

Space and comfort

  • Luxurious and modern with its Alpi® grey oak finished cabinets, and Milano laminate flooring.
  • Even more spacious with the redesigned layout of the salon.
  • High level of comfort with widened double berths in owner and guest cabins.
  • In the owner version, an impressive suite rarely found on catamarans of this size, featuring double cabin, couch, and desk.


  • infusion-moulding for increased weight saving (important for a catamaran), an optimal structure, and greater protection for the environment and shipbuilders
  • interior woodwork in Alpi® reconstituted wood, a sustainable source
  • vertical glazing for better protection against the sun and optimal space and height below deck
  • gull-wing bridge deck for greater comfort in heavy seas
  • wide choice of layouts including 3 or 4 cabins and 2, 3 or 4 washrooms
  • VPLP design: performance under sail guaranteed!

Above deck

  • rigid bimini flush with the coachroof for cleaner lines and better protection against the sun
  • easy and safe movement around rear deck
  • transom platforms for easy and safe boarding
  • cockpit and saloon are on the same level
  • Direct communication from the helm position to the cockpit

Below deck

  • plenty of natural light in saloon and cabins (large hull windows)
  • excellent ventilation in all parts of the boat
  • large owner’s cabin with plenty of stowage
  • galley located between cockpit and saloon
  • forward cabins include double bed that converts into twin beds
  • engine compartments are far from the living areas and perfectly insulated


« The Lagoon 400 is a true sailboat. During our trial in Chesapeake Bay, the fact of having two hulls with a pretty powerful combination of sails (gennaker and mainsail), allowed us to reach 5.2 knots reaching in 7-knots of wind.  »
Cruising World, USA – March 2010

« When we set off in the Lagoon 400, a south-westerly wind gusting to 30 knots was blowing over Chesapeake Bay (…). The boat thrived in these conditions under mainsail with one reef and jib, sailing at 7 knots or more, at an angle of 35-40° (apparent) from a 25-knot wind. »
Sail Magazine, USA- January 2010

« In a rapidly freshening breeze (…) of up to 25 knots, we maintained a speed of 8.5 to 9 knots, sailing at 55° from true wind, with the fin keels working perfectly to counter leeway.  »
