Design and Construction
The 380’s hulls are built from a foam-glass-polyester composite with vinylester resin below the waterline, while the deck uses a balsa sandwich; the polyester lamination is laid up by contact in a female mould at the Vendée-based Beneteau factories. Practical Sailor notes the structure as glass-reinforced polyester sandwich fiberglass described as very strong and durable. The silhouette that drew early criticism is now considered thoroughly acceptable, and the vertical portholes gave the boat a modern, functional signature. A bright engine bay and careful installations mark the build, including a rudder deflection limiter visible on the linking rod. The deck plan is perfectly organized and all fittings are worthy of praise, reinforcing the manufacturer’s claim of a smart and durable design that seduced recreational and professional sailors alike.
Rig and Handling
The 380 is a fractional sloop carrying 829 square feet of upwind sail area, with a 47–48 square metre mainsail and 30–31 square metre genoa or jib, and the capacity to fly a 52–85 square metre spinnaker or gennaker. The helm station sits on the port side of the cockpit rather than on an upper level, keeping the helmsman within the social space yet offering 360-degree visibility above the cabin; all navigation screens, engine and sail controls sit within easy reach. A large electric winch with foot controls and roller-bearing cars makes the full-batten mainsail easy to raise and douse, while the 100% jib runs on a Harken roller furler with sheets led aft to the helm, as are the mainsail single-line reefing lines. Genoa cars on the coach roof give a wide adjustment range. Though no light-air sail was standard, the deck hardware supports a gennaker. Practical Sailor found her extremely maneuverable in close quarters using only the twin engine controls, able to turn almost within her own length like a tracked vehicle. In 10 to 17 knots the reviewer maintained 7 to 10 knots close-hauled, and as a catamaran she heels very little even at speed.
Accommodations
Every space aboard is functional and comfortable, with smooth circulation from the cockpit through the saloon. Two layouts exist: a four-cabin, four-head charter version and an owner’s version with three cabins and two heads. The owner’s layout turns the starboard hull into a mini-suite with a queen berth aft, extra storage, seating and shelves, plus a forward head with a large separate shower; a clever sliding door closes off that hull. The port hull holds a queen aft, combination head/shower, and a forward double with ample lockers. The main cabin gives a 360-degree view, light and airflow from two opening ports, and electric fans throughout. Interior surfaces are easy-clean fabric rather than hot leather or vinyl, with smooth fiberglass ceilings, walls and floors with rounded corners; cabinets, doors, chart table and stateroom areas are finished in teak. The cockpit dining table and saloon table interchange as needed, and the cockpit itself seats four adults comfortably. Berths number between six and twelve depending on configuration.
Known Issues
A reviewer with over 35 years of bareboat chartering experience recommends adding a cover over the bow chain guide structure or rail for safety, as the exposed setup would be safer with that modification.
Refits and Ownership
The Club version is not a discount boat; it differs from the Premium chiefly in secondary equipment such as the 220V installation, engine isolation, stowage, pulpits, specific soft furnishings and saloon settee. Over 760 examples were built between 1999 and 2008, and the model’s convenient size and easy liveability keep it a favorite among cruisers. The anchoring installation lives up to expectations, with a windlass hidden in a bow locker, ample chain and a plow anchor, while built-in davits handle a large dinghy and outboard and a stern cavity stores a deployment-ready safety raft for ocean use.
The Verdict
The Lagoon 380 succeeds as a relaxed, safe cruiser that is pleasant to sail in all conditions and intuitive to handle, with a durable composite build and a genuinely thoughtful deck and interior plan. She trades excitement for liveability and represents the easy, level cruising catamaran trend at its best.
Pros
- Best-selling liveaboard multihull with proven smart, durable design
- Shallow draft and twin-engine maneuverability simplify close-quarters handling
- Owner’s version delivers a private mini-suite hull with flexible social spaces
- Easy sail handling from electric winch, roller furler and led-aft controls
Cons
- Exposed bow chain guide rail could use a safety cover
- No standard light-air sail despite deck hardware to fit one
- Early silhouette drew criticism before gaining acceptance
