Van Peteghem-Lauriot Prévost drew the boat, while Hervé Couëdel and Pierre Hugon handled the interior styling. The pair had previously collaborated on the Bordeaux 60 and Wauquiez 55. Presented at the Cannes Boat Show, the 620 was received as the most impressive genuine production catamaran built to that point: a true private owner’s boat that also appealed to buyers considering luxury charter.
Design and Construction
The Lagoon 620 measures 18.90 meters overall, with an 18.20-meter waterline, a 10.00-meter beam, and a 1.55-meter draft on twin keels. Empty displacement is 30 tonnes.
VPLP’s hull engineering and Lagoon R&D’s oversight produced a boat certified under CE category A for 14 people and category D for 30. The interior architecture by Couëdel and Hugon was aimed at owners attracted to the stability and volume inherent in catamarans. The two-year development effort produced the most substantial production multihull of its era.
Accommodations and Living Space
Lagoon offered several interior arrangements, ranging from three to five double cabins. Every cabin has an island bed and its own ensuite head with a separate shower stall, a level of accommodation that emphasizes the boat’s liveaboard intent.
In one layout, the galley occupies the aft end of the port hull. It can be reached from the saloon or directly from the deck through its own companionway. This separation keeps cooking smells out of the main living area while allowing the galley to serve crew on deck.
Outside, a rigid aft-deck awning extends the saloon roof to shelter a large dining area with a wet bar. The broad deck plan also provides quiet corners for guests, even when the boat is at full capacity. A Cruising World reviewer noted that the fly bridge serves as both the control station and another social area.
Rig, Machinery, and Handling
The Lagoon 620 carries a fractional sloop rig. Auxiliary power comes from twin 150 PS diesel engines with direct drive. Tankage comprises 1,376 liters of fuel and 960 liters of water.
Port and starboard helm stations give the skipper options when docking, along with clear views of the sails and surrounding water. Moving the cockpit to the fly bridge leaves the entire main deck open for guests to move around, though it also places the helm physically apart from the saloon below.
Twin independent throttles and the split steering positions make close-quarters maneuvering primarily a matter of engine control rather than sail-dependent agility.
Verdict
The Lagoon 620 was a genuine production milestone: a 62-foot catamaran designed for private ownership but also suited to charter, with a flexible cabin plan, ensuite accommodations throughout, and a sheltered aft social area.
Its CE category A certification and 1.55-meter draft on twin keels suit bluewater passage-making. Meanwhile, the fly-bridge helm and separated galley reflect a design focused on volume and livability rather than stripped-back racing performance.
Pros
- Three to five double cabins, with up to five island beds; every cabin has a private ensuite head and shower stall
- Rigid aft awning shelters a large dining area with a wet bar
- Broad deck space provides private retreats for guests
- Twin helms and twin 150 PS engines assist with docking and visibility
- CE category A certification for 14 people and 30-tonne empty displacement indicate serious offshore capability
Cons
- Fly-bridge helm separates the skipper from social activity on the main deck
- 1.55-meter draft restricts access to shallow anchorages compared with centerboard catamarans
- The large beam and displacement require careful marina handling in windy conditions
