Lagoon 380

1999–2019 · designed by Marc Van Peteghem and Vincent Lauriot-Prévost (VPLP) · built by Lagoon

Compact cruising catamaran offering separate sleeping hulls, a shared saloon and cockpit, and three- or four-cabin accommodation. Its practical appeal is living space within a sub-12-metre length; evaluate that space against the buyer's berth, load and maintenance plans.

Check this first — Includes the 380 family and later S2, Club and Premium labels. Confirm owner versus four-cabin layout, actual engine installation and equipment from the hull records. Dimensions below follow Lagoon's published baseline; light displacement is not a loaded cruising weight. The new Lagoon 38 is a separate design.

This is a general read on the Lagoon 380 class — informed background, not a verdict on any individual boat. Condition, refit history, and how a particular hull was sailed and stored matter far more than class reputation. Use it to know what to look for; for a read on a specific listing, run a free FairKeel report on that boat.

What the Lagoon 380 is known for

Three- and four-cabin choices allow different balances of private accommodation and guest capacity.
Lagoon publishes 1.15 m draft, useful when screening cruising grounds for depth constraints.

Known trade-offs

Check the availability and cost of berthing and lifting for a 6.53 m beam before comparing ownership costs by length alone.
Added equipment can consume carrying capacity. Obtain the builder plate and an inventory of later additions rather than relying on brochure displacement.

Age-related quirks to expect

Owner and four-cabin layouts trade private space against guest capacity; cabin count does not establish past charter use. severity: Low affects: all; layout specific

Factory engine specifications vary across documentation editions; match both installed engines and drives to their own service records. severity: Medium affects: all; installation specific

Later-build GOIOT emergency hatches: if affected, verify retention-bracket recall work and the separate ten-year replacement requirement. severity: High affects: 2007–2019 builds, only with the affected fixed GOIOT hatches

Systems to check before you buy

Hull, deck and bridgedeck priority: offshore, coastal, liveaboard

The manual describes balsa sandwich with solid laminate underwater. Ask the surveyor to map moisture and repairs around fittings and openings, and relate any finding to its structural location.

Twin propulsion priority: offshore, coastal, liveaboard

Request separate hours, serial numbers and maintenance invoices for each engine and drive. Compare cold starts and loaded running; a record for one side leaves the other unverified.

Steering and emergency access priority: offshore, coastal, liveaboard

Demonstrate the emergency tiller and access to each rudder stock. Have steering travel, attachments and play checked before treating a dockside wheel test as sufficient.

Rig and deck fittings priority: offshore, coastal, liveaboard

Ask for rig inspection and replacement records. Include mast support, chainplates, reefing gear and the bedding around loaded deck fittings in the survey brief.

Windows and escape openings priority: offshore, coastal, liveaboard

Inspect glazing, frames and surrounding laminate for leaks or repairs. Confirm emergency access remains usable after interior changes.

How it fits your plans

Coastal: A useful candidate where shallow draft and separated accommodation fit the crew. Check actual berth and haul-out access before committing.
Offshore: Assess the specific boat's loading, structure, rig and emergency arrangements. A class guide cannot establish passage readiness.
Liveaboard: Compare owner and four-cabin plans with daily privacy, ventilation and storage needs; assess additions against the boat's load limits.
Motor: Plan for two machinery service histories and demonstrate control on each engine.
Weekending: The space may suit guests, but the whole platform still needs upkeep between short trips.

This guide is the class. A report is that hull. Paste the listing you're looking at and FairKeel grades every claim in it against what's known about the Lagoon 380 — where the evidence is thin, the red flags worth a second look, the costs likely to land in your first season, and whether the boat suits the plans you describe in a few short questions.

It won't read the photos or put a number on the boat — that's the $249 Deep-Dive, and for the real answer, a surveyor. It will tell you when a Deep-Dive isn't worth buying. Free, no account, usually a minute or two.
