Lagoon 37 Buyer's Guide
The Lagoon 37 is the smallest catamaran Lagoon built, produced from the early 90s in relatively small numbers and dedicated mainly to charter before being chosen by Moorings as the Moorings 3700. For a buyer on the used market, that charter lineage shapes what you will find: ex-charter examples are common, and the four-cabin layout is the more common on the used market, though both two- and three-cabin versions exist and are available. Knowing the documented structure, rig, and access points turns a generic catamaran search into a targeted inspection of a specific, well-defined design.
Layouts on the Used Market
The Lagoon 37 was offered in 2, 3, or 4-cabin versions, with the saloon occupying practically the whole volume of the nacelle and an aft-facing U-shaped settee below large cabin-top windows and two opening hatches. The chart table and galley are partly pushed into the middle of the hulls, and sleeping comprises two queen-size forward doubles plus a smaller starboard-aft double, with an optional walk-through second head amidships in the starboard hull. Charter four-cabin layouts are the more common on the used market, but both are available; ex-charter examples are common, so expect higher cabin counts and heavier wear on the bright teak-and-Formica interior than on a private-owner boat.
Equipment and Common Upgrades
On the used market, lithium batteries, short-handed setups, watermakers, air conditioning, and solar are commonly fitted, while self-tacking jibs, spinnakers, asymmetric spinnakers, hot water, biminis, hardtops, trampolines, teak decks, radar, AIS, autopilots, chartplotters, life rafts, and boats with a circumnavigation or transatlantic completed are often seen. The standard boat carried hot and cold pressure water, a 12-gallon engine-heat-exchange hot water heater, twin 18-horsepower Perkins M20 diesels, four 85-amp-hour deep-cycle batteries, and bilge pumps in each hull, so many often-seen items are additions rather than replacements. The standard rig is modest with a near-straight-roach mainsail, and one owner gained almost 6 square meters on the mainsail alone, a refit path frequently mirrored in the brokerage fleet.
What to Inspect
Documented construction on the Lagoon 37 uses Baltek end-grain balsa core throughout the hulls and deck, sandwiched between triaxial glass fiber hand laid in vinylester resin, with the hull-to-deck joinery bonded chemically via an inward flange and high-strength two-part urethane adhesive. Mechanical fasteners at stanchion bases and deck cleats are not part of that primary bond, so inspect those penetrations for independent leakage or corrosion rather than assuming structural integrity. The port engine is accessed only through a large bulkhead opening in the head, and the starboard unit is fully accessed through a large hatch beneath the aft berth; verify both access paths are clear and that head-bulkhead structure is sound. Bilge-water evacuation relies on an automatic electric pump and a manual pump in each hull, so test both per hull for operation and trace any history of flooding or neglected manual pumps.
Availability and Buyer's Takeaway
The typical market for the Lagoon 37 is the United States. For a shopper, the takeaway is straightforward: confirm the cabin count you want against the dominant four-cabin charter layout, verify the chemically bonded hull-deck joint and through-deck fasteners, exercise both bilge pump systems in each hull, and confirm engine access on both sides before committing.
- Charter four-cabin examples common; two- and three-cabin versions available
- Inspect chemically bonded hull-to-deck joint and thru-deck fastener penetrations
- Test automatic and manual bilge pumps in each hull
- Confirm starboard-aft-berth and port-head engine access paths
- Prefer deep 1.24 m stub keel over 0.93 m shallow draft for windward work
