Design and Construction
The 620 measures 18.90 meters overall with a 10.00-meter beam and an 18.20-meter waterline, drawing 1.55 meters on its twin keels. Empty displacement sits at 30 tonnes. VPLP's hull engineering and the Lagoon R&D oversight produced a vessel certified under CE category A for 14 persons, extending to 30 under category D — a clear statement of its offshore-rated capacity. The interior architecture, credited to Couëdel and Hugon, targets owners drawn to the stability and volume inherent to catamarans, and the completion effort behind the design spanned a two-year technical marathon yielding the most substantial production multihull of its era anchor.
Accommodations
Lagoon cut the interior several ways, offering as many as five double cabins or as few as three. Every cabin provides an island bed and its own ensuite head with a stall shower, a layout density that underscores the boat's liveaboard intent. In one arrangement the galley occupies the aft end of the port hull, reached both from the saloon and independently from the deck via its own companionway — a separation that keeps cooking smells out of the main living space while serving crew on deck. The rigid aft-deck awning extends the saloon roof overhead, sheltering a large dining area with a wet bar, and the broad deck plan leaves quiet corners for everyone even at full guest capacity. Writing in Cruising World, the reviewer noted the fly bridge doubles as both control station and a further socializing zone anchor.
Rig and Handling
The 620 carries a fractional sloop rig and is driven by twin 150 PS diesel engines on direct drive, with 1,376 liters of fuel and 960 liters of water aboard. Port and starboard helms give the skipper docking options and clear sightlines to the sails and surrounding water. By lifting the cockpit to the fly bridge, Lagoon freed the entire main deck for guest flow, though the helm is physically removed from the saloon below. The combination of twin independent throttles and split steering positions makes close-quarters maneuvering a matter of engine control rather than sail-dependent agility.
The Verdict
The Lagoon 620 is a genuine production milestone: a 62-foot catamaran engineered for private ownership yet charter-capable, with a flexible cabin plan, full ensuite accommodation, and a sheltered aft social space. Its CE A certification and twin-keel 1.55-meter draft suit bluewater passage-making, while the fly-bridge helm and separated galley reflect a design philosophy built around volume and livability rather than stripped racing function.
Pros
- Up to five island-bed double cabins, each with private ensuite head and stall shower
- Rigid aft awning shelters large wet-bar dining area; deck space allows private retreats
- Twin helms and twin 150 PS engines aid docking and visibility
- CE A:14 certification and 30-tonne displacement indicate serious offshore capability
Cons
- Fly-bridge helm isolates the skipper from main-deck social activity
- 1.55-meter draft limits shallow anchorage access compared with centerboard cats
- Large beam and displacement demand careful marina handling in wind
