The Lagoon 400 was introduced in 2009 as a pivotal bridge between the entry-level Lagoon 380 and the larger blue-water cruisers in the manufacturer’s fleet. Designed by the esteemed naval architects at VPLP Design, the 400 was engineered to maximize volume and comfort without sacrificing the maneuverability required for a couple to handle the vessel alone. Replacing the earlier Lagoon 410, the 400 featured a more modern, angular aesthetic and the signature vertical wrap-around windows that have since become a hallmark of the brand. In 2012, the model underwent a significant interior refresh, rebranded as the Lagoon 400 S2, which focused on softening the interior lines and improving the ergonomics of the living spaces through a collaboration with Nauta Design.

Lagoon 400 Buyer's Guide
The Lagoon 400 was introduced in 2009 as a bridge between the entry-level Lagoon 380 and the larger blue-water models in the brand's fleet. Designed by VPLP and built in France, it replaced the earlier Lagoon 410 with a more modern aesthetic and the signature vertical wrap-around windows that became a Lagoon brand hallmark. A significant interior refresh in 2012 — rebadged as the Lagoon 400 S2 through a Nauta Design collaboration — softened the interior lines and improved living space ergonomics, creating a two-generation market where S2 examples command premiums over early 400 hulls. With a 23'9" beam and 7-foot salon headroom, the boat offers interior volume that rivals many 45-foot monohulls.
What Brokers Highlight
The owner's version — three cabins, entire starboard hull as master suite with island berth, dedicated desk/vanity, and walk-in shower — is the dominant configuration in premium listings. The "4+2" four-cabin charter version adds two forward bow-peak berths for crew or children and appeals to buyers managing charter programs. Brokers frame the owner's version specifically as the liveaboard configuration and price accordingly.
Bleached oak woodwork and custom Corian or brown leather finishes mark S2 interior upgrades. The wrap-around salon sofa, vertical windows, and integration of domestic appliances — 3-burner Eno ovens, washing machines — are called out as evidence of a boat designed around extended habitation rather than weekends.
Off-grid capability defines the premium tier. Solar arrays of 800–1350W on custom stainless arches paired with Epoch or Victron LiFePO4 battery banks (600–920Ah), Victron MultiPlus 3000W inverter/chargers, and Seawater Pro watermakers (40 GPH) are the configuration brokers call "turnkey" for long-term cruising. Starlink Maritime is now appearing as a standard callout in listings targeting remote workers and long-distance cruisers. Square-top mainsails and Harken electric winches (specifically the Harken 46) mark performance-oriented examples.
Yanmar is the near-universal engine choice: 3JH4E/3JH5E (39–40hp) on SD50 or SD60 saildrives is the baseline; 4JH5E (54hp) appears in offshore-configured examples. Raymarine Axiom 12 chartplotters with AIS700 transceivers replacing legacy Raymarine ST series are now the expected electronics upgrade in premium listings.
What to Look For When Buying
Bulkhead structural integrity is the most important inspection item on this model. Documented reports in surveyor circles and owner forums have noted movement in the main structural bulkheads — particularly in 2010–2011 hulls — under heavy offshore load. The "reinforcement of the main transverse bulkhead" appears explicitly as a maintenance callout in several listings from this era. Inspect the tabbing carefully; listen for creaking during sea trial; have a structural surveyor specifically evaluate this area.
Goiot escape hatches: like the Lagoon 380 and 420, the 400 was equipped with these hatches and they were subject to the same adhesive failure safety notice. Verify replacement or bolt-through upgrade documentation before purchase.
Standing rigging on original 400 models has reached the 10-year replacement threshold expected by most offshore insurers. Listings that specifically document new rigging (shrouds, forestay, diamond rigging) are advertising a cost already absorbed. On hulls without this documentation, budget the replacement into the purchase.
Saildrive cones on high-use charter units may show significant wear. Brokers for high-hour listings specifically call out "rebuilt cones" as a value signal. Verify saildrive hours and service history alongside engine hours.
Rudder bearings can wear in silty anchorages or when steering systems aren't regularly lubricated, leading to play or stiffness. Inspect for any looseness in the helm during sea trial.
What Drives Pricing
Supply is moderate and prices have been declining — the 400 is aging into the market where buyers are weighing the cost of lifecycle updates against the purchase price. This creates value opportunities for buyers willing to invest in bulkhead verification, rigging, and saildrive service on hulls that haven't absorbed those costs yet.
Compared to the Lagoon 380, 440, and 450, the 400 occupies a specific window: more interior volume and bridge deck clearance than the 380, roughly comparable to early 440 models, and significantly less expensive than a 450. The S2 is worth a meaningful premium over early 400 hulls for the interior refinements and the additional years of production quality improvements.
The Bottom Line
The Lagoon 400 remains one of the most successful 40-foot catamarans ever built for good reason: it balances interior volume, bridge deck clearance, and brand support infrastructure in a package that remains highly functional for its intended purpose. Bulkhead integrity and escape hatch verification are non-negotiable items in any pre-purchase survey. A well-maintained S2 owner's version with documented rigging replacement and modern electrical systems is a strong offshore cruising value in the current declining-price market.
