Lagoon 380 Review: Two Decades, One Thousand Hulls (2026)

What the Lagoon 380 actually is

The Lagoon 380 is an 11.55 m (37 ft 11 in) cruising catamaran designed by Van Peteghem / Lauriot-Prévost (VPLP Design) and built by Lagoon Catamaran, part of the Beneteau Group, in France. Production ran from 1999 to approximately 2019, making it one of the longest-running models in production catamaran history. Multiple sources describe it as the best-selling cruising catamaran ever built, with roughly 1,000 hulls launched over that two-decade span (as of August 2026). The exact production count is disputed: Wikipedia cites about 1,000, boat-specs.com records 548 for the original 380 alone, and other sources say "over 760." Treat any single figure as approximate.

Hull construction is polyester/vinylester resin with balsa sandwich topsides and solid fibreglass below the waterline. The deck is entirely balsa-cored. Twin mini-keels give a standard draft of just 1.15 m (3 ft 9 in), which opens up anchorages that deeper monohulls or performance cats simply cannot reach.

Two versions: original and S2

From approximately hull #300 onward (c. 2003–2004), Lagoon introduced the S2 variant with 17 improvements: larger hull-side windows, a sliding door for the owner's cabin, improved refrigeration, and more galley counter space. If you're shopping used, the S2 designation matters. It indicates the updated model that ran until the end of production. Available in 3-cabin (owner version) or 4-cabin (charter version) layouts, the 380 accommodates 6 to 12 berths depending on configuration.

The 380's charter pedigree runs deep. It was co-branded and sold as the Moorings Lagoon 380 and became one of the most widely deployed bareboat charter catamarans of its era. That means many used examples have charter miles on them. Budget for a thorough survey, not just a quick walk-through.

The rig is a fractional Bermuda sloop with a deck-stepped aluminium mast, swept diamond spreaders, and a full-battened mainsail. Total upwind sail area ranges from 77 to 82 m² depending on the variant. Twin Volvo Penta or Yanmar diesels (20–29 hp per engine) drive saildrives, with fuel capacity of 200–240 litres and water capacity of 300 litres.

Production ended around 2019. The Lagoon 40 now occupies the entry-level slot in Lagoon's range.

What owners consistently praise

A boat does not become the world's best-selling cruising catamaran without getting a lot of things right. Over two decades and roughly 1,000 hulls, owners return to the same strengths again and again.

Forgiving, confidence-building handling

The Lagoon 380 is a boat that rewards rather than punishes its crew. Toast, skipper of S/V Don Quixote, sailed a 2001 model for approximately six years from Seattle to New Zealand and summed it up: "She's indestructible. A very forgiving boat" (CatamaranSite, approx. 2020). The wide 6.53 m beam, level sailing attitude, and shallow draft (1.15 m standard) make the 380 accessible to families and first-time catamaran owners without sacrificing the ability to cross oceans.

Overbuilt rig and hardware

The standing rigging is not a cost-cut area. One liveaboard owner noted: "Rigging is of high quality stainless steel, beefier than it needs to be" (user 'honeymoon', SailBlogs, 2010-02-04). The fractional rig with swept diamond spreaders is straightforward to maintain, and the full-battened mainsail depowers cleanly when you need to reef. For a production boat in this price class, the rig quality stands out.

Practical engine access

Engines are accessed from the transoms rather than from under the berths, which is the arrangement on many competitors. This makes routine maintenance tasks (oil changes, filter swaps, belt checks) meaningfully easier and also reduces cabin noise intrusion under power.

Shallow-water access

At 1.15 m draft with standard twin keels (approximately 1.20 m with skegs), the 380 reaches anchorages that most 38-foot sailboats cannot. The Bahamas, the ICW, shallow Greek bays, and thin-water Caribbean cruising grounds are all open.

Strong resale and community

The 380 holds its value well on the used market, a notable feat given the sheer number built. Katamarans.com called it out explicitly. The massive production run also means an enormous body of shared knowledge: forum threads, YouTube walkthroughs, parts suppliers, and independent mechanics who know every system. That community is a tangible asset when something breaks.

Capable off-wind sailing

On a beam or broad reach, the 380 is in its element. In the right conditions, speeds of 12 to 13 knots are achievable. Under power, expect 7 to 8 knots at roughly 2,500 RPM. A gennaker option (52 to 85 m² depending on specification) transforms downwind legs for owners willing to invest in the sail and put in the crew work to fly it.

Sailing performance

The Lagoon 380 is not a performance catamaran. Understand that upfront, and you'll either accept the compromise or move on to something with daggerboards.

On a beam or broad reach, the 380 delivers honest, real-world speeds of 12 to 13 knots in favourable conditions, confirmed across multiple owner accounts. Under power, 7 to 8 knots at roughly 2,500 RPM is the standard.

The upwind reality

Upwind in under 10 knots of breeze (Beaufort Force 3 or less), the 380 is slow. Most owners resort to motoring. The twin fixed mini-keels with no daggerboards compromise pointing ability. Wide hulls and low-aspect keels are the structural cause. If your sailing grounds involve regular windward work in light air, think the Aegean in July, factor in diesel costs and patience.

One owner who sailed a 2001 model from Seattle to New Zealand put it plainly: "It's really easy to overload them; they sink down on their water line" (Toast, CatamaranSite, approx. 2020). A loaded cruising 380 carrying a watermaker, solar panels, dinghy, and provisions for a transocean passage sits deeper and sails noticeably worse in light conditions. If you plan to cruise rather than charter, be ruthless about weight.

The standing rigging, as noted above, is a high point. The fractional rig is straightforward, and the full-battened main depowers cleanly when you need to reef.

Weak points and what they cost

Every boat model has a failure pattern. The 380's is well documented across two decades of owner forums. Here are the seven issues that appear repeatedly.

1. Saildrive seal and bellows deterioration

The rubber seals and bellows on the saildrives require inspection every 5–7 years and replacement when deteriorated. Failure risks flooding the hull, and on a catamaran, a flooded hull is a serious emergency. Saildrive oil and zinc anode changes are required every 100 hours per the Yanmar manual. Multiple threads on Cruisers Forum cover SD40/SD50 replacement issues on the 380 specifically. When surveying, this is inspection item number one.

2. Hull flooding risk from saildrive impact

The engines sit under the aft berths with saildrives penetrating the hull. A collision with a submerged object can breach the hull. SAIL Magazine states directly: "Be aware…that this means your hulls may flood if a saildrive collides with an underwater object." Carry bilge-pump redundancy and keep bilge alarms functional.

3. Balsa-cored deck delamination

The entire deck is balsa-cored. Delamination occurs around high-traffic areas: steps, hatches, and the anchor locker. Tap-test these areas during any survey. SAIL Magazine flagged it explicitly: "The deck is all balsa, so watch out for delamination around heavy traffic areas." A Cruisers Forum thread titled "380 S2 Spongy spot on deck" confirms this is a recurring issue, not an isolated case.

4. Overloading and performance degradation

At a light displacement of 7,260 kg (CE figure), the 380 is easily pushed past its design waterline when fitted out for extended cruising. The gap between light-ship weight (roughly 5,900 kg per one source) and loaded displacement (roughly 7,120 kg) shows how quickly provisions, gear, and upgrades accumulate. Strip what you don't need.

5. Poor after-sales service

One hull #838 owner reported in 2018: "Since the acquisition we have faced many problems and a very weak network of assistance" (anonymous owner, YBW Forum, 2018-08-28). A failed Harken electric winch took five months to repair through the authorised dealer. Cracks in cockpit steps were noted as a warranty item. If buying new-ish, verify dealer proximity and parts availability before signing.

6. Hull paint erosion from cleaning products

Owners on SailBlogs report hull paint erosion attributed to deck soap and cleaning products rather than fender rub. Use catamaran-specific, non-abrasive cleaning products and test on an inconspicuous area first.

7. Light-air upwind limitations

Covered in the performance section above, but worth listing here as a structural weakness, not a user error. No daggerboards, wide hulls, low-aspect fixed keels. This is by design, and it won't change with new sails.

Lagoon 380 price: what the market asks

As of August 2026, we found an estimated 60–90 unique listings globally across YachtWorld (26 listings), boats.com (31), Boatshop24 (17), BoatTrader (14+), and European aggregators including Yachtall and Band of Boats. There is significant overlap between platforms, so the true number of individual boats for sale is lower than the raw listing count suggests.

Price Tier	Approx. EUR	Typical Year / Condition
Entry	~€121,000	Early 2000s original 380, charter history, needs work
25th percentile	~€155,000	Early 2000s, private ownership, reasonable condition
75th percentile	~€210,000	2010s S2, well-maintained, some upgrades
Top end	~€262,000	Late-production S2 (2017–2019), upgraded, private use

Prices are converted from USD at approximately 0.92 EUR/USD where listings were in dollars. A premium outlier was listed at approximately €230,000 for a 2014 S2 in Fiji with significant upgrades. The 380 holds its value well on the used market. That's a notable feat given how many were built.

What drives price variation

Three factors dominate: year (S2 vs. original), charter history, and engine hours. An ex-charter boat with 4,000+ engine hours and a tired interior will sit at the bottom of the range. A privately owned 2017 S2 with new saildrive seals and a recent antifoul will command the top. When comparing prices, also consider that a sailing holiday on a chartered catamaran often works out cheaper than an equivalent hotel stay for families, particularly at this price point where the 380's four-cabin layout can sleep a crew of eight.

Budget €5,000–€10,000 for a thorough pre-purchase survey, saildrive inspection, and immediate maintenance items on any example over 10 years old. That number isn't in the asking price.

Who this boat fits / doesn't

It fits

• Couples or families wanting stable coastal cruising: The shallow draft, wide beam (6.53 m), and level sailing make coastal Med or Caribbean cruising comfortable and accessible for non-sailors aboard.
• First-time catamaran buyers: The 380's production volume means an enormous body of shared knowledge, forum threads, YouTube walkthroughs, parts suppliers, that you simply won't find for boutique builders. As one long-term owner put it: "She's indestructible. A very forgiving boat" (Toast, CatamaranSite, approx. 2020).
• Charter operators on a budget: The four-cabin version remains a proven revenue generator with low operating costs and straightforward systems.
• Thin-water cruisers: At 1.15 m draft, the Bahamas, the ICW, and shallow Greek bays are all accessible.

It doesn't fit

• Windward sailors: If your home waters demand regular upwind work in light air (under Force 3), you'll motor more than you sail. A cat with daggerboards or a well-found monohull is a better tool.
• Weight-conscious bluewater cruisers: The 380's light displacement makes it sensitive to loading. Serious offshore provisioning pushes it past its design waterline, degrading performance and safety margins.
• Anyone expecting strong dealer support: The after-sales network has drawn criticism from multiple owners. Be prepared to manage maintenance yourself or build a relationship with independent marine technicians.
• Tall sailors: Cabin headroom is 188 cm (74 in). If you're over 185 cm, try before you buy.

Verdict

The Lagoon 380 earned its best-seller status by being capable at many things and genuinely bad at very few. It sails well enough off the wind, motors efficiently, fits a family, and draws just over a metre. The construction is honest, and the rig is overbuilt in the right places.

"Capable" is still the operative word, though. The upwind performance ceiling is low. The balsa deck demands vigilance. The saildrives require regular maintenance or they become a flooding hazard. The builder's after-sales support has disappointed enough owners to constitute a pattern, not an anecdote.

The decision is fairly clear. Buy a Lagoon 380 if you want a proven, value-retaining coastal cruising catamaran, provided you're willing to inspect the saildrives and deck core before purchase, budget for immediate maintenance, and accept that you'll motor in light air. Look elsewhere if upwind performance matters to you, if you plan to load it with bluewater gear, or if you expect a dealer to solve your problems.

At the current market range of roughly €121,000 to €262,000 (as of August 2026), the sweet spot is a privately owned S2 from the 2008–2015 era at €170,000–€200,000 with documented saildrive service and a clean deck-core survey. That's where the best value-to-condition ratio sits.
