Lagoon 380 Sailboats for Sale

Layouts on the Used Market

The used fleet splits between two well-established configurations. The four-cabin layout — two equal hulls each carrying a double aft cabin and a forward cabin with a shared head — dominates the market, a direct consequence of charter fleet origins where maximum berth count commanded a premium. Charter four-cabin boats often went through many charter seasons before entering private hands, so their interiors may show wear that the topsides and rig do not.

The owner's version, sometimes called the captain's version, converts the starboard hull into a larger private suite: a queen berth aft, more generous stowage and seating, and a proper separate shower forward where the fourth cabin would otherwise be. The port hull retains a queen aft and a double forward. Many private buyers find this configuration far more livable for extended cruising, and examples do appear on the used market — often at a modest premium or in somewhat better overall condition, having bypassed the charter cycle entirely. Both layouts share the same bright, glassed saloon, the interchangeable cockpit and saloon dining tables, and the helm station set into the port side of the cockpit rather than elevated above it, a configuration that keeps the helmsman in the social flow of the boat.

Equipment and Common Upgrades

The level of fitted electronics and cruising gear varies considerably across the used fleet, but a chartplotter, autopilot, bimini, solar array, and inverter are commonly fitted on the majority of examples that reach the brokerage market. Dinghy davits, an AIS transponder, radar, cockpit shower, and hot water systems are seen frequently enough that their absence on an otherwise well-priced boat would warrant negotiation rather than alarm. Watermakers and air conditioning units appear on a substantial portion of listings, particularly on boats that spent time in the Caribbean or Mediterranean charter trade, where both are effectively standard equipment.

Less universal but worth asking about: lithium battery upgrades are a frequent owner improvement on boats that have made the transition from charter to private use, often paired with additional solar capacity. Electric winches appear on many examples, easing short-handed sail handling considerably. A life raft certified to current standards is worth confirming rather than assuming — charter companies rotate equipment regularly, but boats that have sat for a while may have expired certificates.

Owner upgrades that surface occasionally include a spinnaker or asymmetric gennaker and associated gear, upgraded trampolines, a washing machine tucked into lockers forward, and supplemental heating for higher-latitude use. These are genuine cruising improvements rather than baseline charter fittings, and finding a boat that already carries them saves meaningful outfitting cost.

What to Inspect

The construction is fundamentally sound — foam-glass-polyester composite hulls with vinylester below the waterline and balsa-cored deck — but the balsa deck sandwich deserves careful attention. Delamination and moisture ingress in the balsa deck core are among the most commonly cited structural concerns on aging Lagoon cats of this era; tap-testing the deck systematically and commissioning a professional survey with moisture readings is not optional. Pay close attention around chainplates, stanchion bases, and any deck penetration where water could have been working its way in for years.

The twin diesel installations — typically Yanmar or Volvo units — are generally reliable, but service history documentation is critical. Each engine drives its own shaft and saildrive or stern-drive leg, and the rubber bellows and impellers on those units have finite service lives that are often deferred on charter boats. Confirm when the bellows were last replaced; this is a relatively straightforward job when attended to on schedule and a very expensive one when not. Check both raw water impellers and heat exchangers carefully.

The rudder system includes a linking rod with a deflection limiter — a detail noted even in factory-era reviews as thoughtful engineering — but verify that the steering linkage shows no slop or corrosion. Survey the skegs and the hulls forward for any history of grounding, which is common on boats with charter histories. Osmotic blistering on the bottoms is a known possibility on boats that have lived in warm water for extended periods; factor bottom paint condition and any blister treatment history into your negotiations.

Rigging ages on a curve, and standing rigging that has never been replaced on a boat of this vintage is overdue. Inspect the mast base, boom vang attachment, and spreader roots carefully; the fractional sloop rig is straightforward but not immune to deferred maintenance. Running rigging on charter boats is typically refreshed more reliably than standing rigging, but confirm both. The furling system and any roller-bearing sail cars should operate smoothly without stiffness.

Electrical systems on boats that have been retrofitted with watermakers, air conditioning, and upgraded electronics warrant particular attention — installations added outside a factory environment vary widely in quality. Trace the DC bus and confirm proper fusing and wire sizing throughout.

Availability and Buyer's Takeaway

The Lagoon 380 is one of the most widely available used catamarans in the world. Inventory concentrates in the Mediterranean — France, Spain, Greece, and Italy are well-stocked markets — and in the Americas, particularly the Caribbean, the eastern US seaboard, and to a lesser extent the Gulf coast. The Martinique (MQ) market reflects boats transitioning out of Caribbean charter fleets. Pacific examples appear but less commonly.

The depth of the market works in a buyer's favour: you are negotiating from a position where comparable boats are genuinely plentiful, and a seller's ask that doesn't reflect known issues has real competition. The flip side is that the best-maintained examples do move; if you find a well-documented boat with verifiable service records, clean survey results, and good equipment, moving decisively makes sense.

Buyer's checklist before making an offer:

• Commission a full survey with moisture readings across all deck and hull surfaces
• Obtain complete engine service records and confirm saildrive/sterndrive bellows replacement history
• Tap-test the entire deck, especially around chainplates, stanchion bases, and hardware penetrations
• Inspect rudder linkage, steering system, and skegs for grounding history
• Verify standing rigging age and inspect spreader roots and mast base
• Confirm life raft certification is current
• Audit all secondary electrical installations (watermaker, AC, batteries) for quality and fusing
• Clarify the layout — four-cabin versus owner's version — and confirm it suits your actual crew needs
• Ask specifically whether the boat came from a charter programme and, if so, how many seasons
