At just under 38 feet overall, with a 21.5-foot beam and a shallow 3.8-foot draft, the 380 packs remarkable volume into a manageable footprint. It also marked a turning point in Lagoon’s visual language, introducing the distinctive vertical portholes later carried over to the Lagoon 470 and 570.
Design and Construction
The hulls are built from a foam-glass-polyester composite, with vinylester resin below the waterline, while the deck uses a balsa sandwich. The polyester laminate is laid up by contact in a female mould at Beneteau’s factories in the Vendée. Practical Sailor describes the structure as glass-reinforced polyester sandwich fiberglass and calls it very strong and durable.
The silhouette drew criticism when the boat first appeared, but it is now considered thoroughly acceptable. Those vertical portholes gave the 380 a modern, functional signature and were later carried over to the Lagoon 470 and 570.
Build details include a bright engine bay, careful installations and a rudder deflection limiter visible on the linking rod. The deck plan is perfectly organized, and all fittings are worthy of praise. Together, these details reinforce the manufacturer’s claim that the 380’s smart, durable design appealed to recreational and professional sailors alike.
Rig, Helm and Handling
The Lagoon 380 is a fractional sloop with 829 square feet of upwind sail area. Depending on specification, it carries a 47–48 square metre mainsail and a 30–31 square metre genoa or jib. It can also fly a 52–85 square metre spinnaker or gennaker.
Rather than placing the helm on an upper level, Lagoon set it on the port side of the cockpit. This keeps the helmsman in the social space while still providing 360-degree visibility above the cabin. Navigation screens, engine controls and sail controls are all within easy reach.
A large electric winch with foot controls and roller-bearing cars makes the full-batten mainsail easy to raise and douse. The 100% jib uses a Harken roller furler, with its sheets led aft to the helm along with the mainsail’s single-line reefing lines. Genoa cars on the coach roof provide a wide adjustment range. No light-air sail was standard, though the deck hardware supports a gennaker.
Practical Sailor found the boat extremely maneuverable in close quarters using only the twin-engine controls. The reviewer reported that it could turn almost within its own length, like a tracked vehicle. In 10 to 17 knots, the reviewer maintained 7 to 10 knots close-hauled. As a catamaran, the 380 heels very little even at speed.
Cockpit and Accommodations
Every space aboard is functional and comfortable, with smooth circulation between the cockpit and saloon. The main cabin offers a 360-degree view, along with light and airflow from two opening ports. Electric fans are fitted throughout.
Two layouts were offered: a four-cabin, four-head charter version and a three-cabin, two-head owner’s version. In the owner’s layout, the starboard hull becomes a mini-suite. It includes a queen berth aft, extra storage, seating and shelves, plus a forward head with a large separate shower. A clever sliding door closes off the entire hull.
The port hull contains an aft queen berth, a combination head and shower, and a forward double cabin with ample lockers. Depending on the configuration, the boat has berths for six to twelve people.
Interior surfaces use easy-clean fabric rather than hot leather or vinyl. The fiberglass ceilings, walls and floors are smooth, with rounded corners, while the cabinets, doors, chart table and stateroom areas are finished in teak.
The cockpit seats four adults comfortably. Its dining table and the saloon table can be interchanged as needed, adding flexibility to the two social spaces.
Deck Equipment and Stowage
The anchoring installation lives up to expectations. The windlass is concealed in a bow locker, with ample chain and a plow anchor. Built-in davits can carry a large dinghy and outboard, while a cavity in the stern stores a deployment-ready safety raft for ocean use.
Known Issue
A reviewer with more than 35 years of bareboat-chartering experience recommends fitting a cover over the bow chain-guide structure or rail. In the reviewer’s view, the exposed arrangement would be safer with that modification.
Versions, Production and Ownership
The Club version isn’t a discount boat. It differs from the Premium chiefly in secondary equipment, including the 220V installation, engine isolation, stowage, pulpits, specific soft furnishings and the saloon settee.
More than 760 Lagoon 380s were built between 1999 and 2008. The model’s convenient size and easy liveability continue to make it a favorite among cruisers.
The Verdict
The Lagoon 380 succeeds as a relaxed, safe cruiser that is pleasant to sail in all conditions and intuitive to handle. It combines durable composite construction with a genuinely thoughtful deck and interior plan. The boat trades excitement for liveability and represents the easy, level-cruising catamaran trend at its best.
Pros
- Best-selling liveaboard multihull with a proven smart, durable design
- Shallow draft and twin-engine maneuverability simplify close-quarters handling
- Owner’s version provides a private mini-suite hull and flexible social spaces
- Electric winch, roller furler and controls led aft make sail handling easy
Cons
- Exposed bow chain-guide rail could use a safety cover
- No standard light-air sail, despite deck hardware that supports one
- The silhouette drew early criticism before gaining acceptance
