The Lagoon 400 S2 is essentially the Lagoon 400 but with an overhauled interior design. The 400 S2 is a reworking by two notable naval architects who determined that the 400 was lacking in space, style, and aesthetic appeal.
Sailors interested in the Lagoon series of boats will find the 400 S2 a smartly upgraded vessel that takes into consideration comfort as well as operation.
Accommodations
The Lagoon 400 S2 was designed to create more space for the general living areas and cabins. The design included widening the spaces to the point that the salon and cabins resemble a small apartment more than the below deck of a boat.
This gives the passengers a cozier, more relaxed setting in which to conduct their daily routines, mealtimes, and group gatherings when the weather is not cooperative for outdoor activity.
Interior
The interior was the main focus of the upgrade from the original 400 design, so the most detailed work was done for this part of the boat.
In addition to larger spaces, the interior was also outfitted with modernized flooring and wood paneling, up-to-date furniture designs, and new layouts for furnishings that make the space more livable.
Extra storage was also added for convenience. The 400 S2 can comfortably house up to eight passengers if necessary.
Exterior
The exterior of the 400 S2 was kept nearly identical to the 400. Retained was the square, symmetrical theme of the boat’s outer design, making straight lines and a clean profile.
The deck is kept simple and neat, allowing sailors to move around with ease. The cockpit is on the same level as the salon and is properly protected from the sun’s rays making navigation less demanding.
Lagoon 400 S2 Vs 400
A chief complaint about the Lagoon 400 is that the boat wastes a lot of usable space. Inadequate storage accommodations, dated decorating choices, and cramped living quarters were the norm for the 400. The 400 S2 is most notable for its redesigned interior.
Sailors seeking a more comfortable cruising experience would likely choose the 400 S2, but others, especially sailors accustomed to the old 400 design, may not feel any particular in upgrading to the more modern version.
Lagoon 400 S2 Vs 380
The Lagoon 380 offers plenty of space, nice views, and a straightforward design scheme. It also has the much-lauded bilge pumps installed.
However, the 400 S2 offers better sun protection at the helm, a more powerful motor, increased storage space, and a sleeker design. The 380 is a smaller vessel that requires less fuel but will not accommodate as many passengers as comfortably as the 400 S2.
Why Sail the Lagoon 400S2
- Increased space in cabins and common areas
- Modernized furnishings, paneling, flooring, and cabinetry
- Airy and well-lit below deck (with natural light)
- Ample storage
- The engine is located away from living spaces, making for a quieter cruise
- Sails competently in windy weather and choppy water
In Conclusion
In the 400 S2, the 400 has gone from a serviceable boat design to a comfortable, well-thought-out vessel that takes into account the people on board who will occupy the space.
The thoughtful overhaul was intended to upgrade the interior and add more openness to the layout of the boat. This open feeling creates a better sense of freedom, encouraging relaxation and enjoyment of the trip.
A 400 S2 is not designed for luxury but rather hominess and stability. This vessel is reliable, sturdy, and rarely suffers from machination errors or malfunctions, making it a trustworthy ocean yacht to charter.

There really is a LOT of room in a boat isn’t there? I had no idea, but the photos and in particular the cross section image shows just how spacious this is. Another very well written and extremely appealing article, thanks 🙂

Hi Kerrie,
You welcome and hope to see you soon on board!
Have a great day
I sail a 400s2 just recently demasted for complete new standing rigging and new mechanicals on mast. I motor here in Thailand with 2 40hp yanmars sail huge main at 8 to10 knots consistently I have currently a 120 Genoa loaded but am moveing up to a 150 for more serious pulling power. The boats slow to my likeing but there built strong so I’m not too concerned with over powering her, but I do use safety and common sense , my David’s do not hold the tender high enough to escape the hull vacuumed wave lift so I constantly trying hard,I am a short guy and need a foot step to see over all those elec winches on the face of the helm ,I do love the boat as I’m a live aboard and have done many upgrades I’m not happy with my interior gallyfridge but that’s easy to change out once I go back to Philippines, currentlysailing Thailand at yachthaven marina
Hey Thomas,
Sounds like you’re really enjoying the boat and getting the most out of her. The 400s2 is a strong, honest boat and carries sail well when used with a bit of common sense. Moving up to a 150 should give you some extra punch in lighter winds. She may not be the fastest, but she’s comfortable and forgiving. The davit drag and helm layout are things most liveaboards learn to work around. All in all, it sounds like a great setup and a boat that’s taking good care of you.
