Lagoon 620 Information, Review, Specs

Crafted under the auspices of Groupe Beneteau, Lagoon's strategic acquisition by the larger conglomerate in 1995 provided the resources to develop such a substantial vessel. The 620 is a testament to Lagoon's dedication to creating yachts that offer "elegance, comfort, and reliability," making her a popular choice for both private ownership and high-end charter operations.

History and Design

The Lagoon 620's journey began with its introduction in 2009, aiming to provide a larger, more luxurious offering within Lagoon's acclaimed cruising catamaran lineup. The design was a collaborative effort, stemming from the long-standing partnership between Lagoon's in-house R&D department and the esteemed French naval architecture firm VPLP Design (Van Peteghem Lauriot-Prévost). This collaboration is a hallmark of Lagoon's design philosophy, ensuring a consistent blend of hydrodynamic efficiency and distinctive aesthetics.

Lagoon, originating from Jeanneau Technologies Avancées, carried forward a strong commitment to innovation and engineering excellence into its cruising designs. For the 620, the goal was clearly to build upon the success of previous large models, emphasizing voluminous interiors, seamless indoor-outdoor living, and robust construction suitable for global voyaging. A significant evolution of the model is the Lagoon 620 NEO, a revolutionary "upcycling project" that blends luxury with sustainability and innovation, indicating ongoing development even after its initial launch.

Sailing Performance and Handling

The Lagoon 620, despite its substantial size and emphasis on comfort, offers commendable sailing performance for a vessel of its class. With a reported sail area of 2550 square feet and a displacement of 71,076 pounds, her Sail Area to Displacement ratio (SA/D) calculates to approximately 23.40. This relatively high ratio for a cruising catamaran suggests good responsiveness in lighter winds, allowing the boat to maintain decent speeds even when conditions are not exceptionally breezy.

The Displacement to Length (D/L) ratio, calculated at approximately 333.9, indicates a heavy displacement for her waterline length, which is characteristic of a comfortable, stable cruising platform designed to carry significant stores and endure various sea states. While not a performance racer, this mass contributes to a comfortable motion offshore. The catamaran hull form, built with fiberglass foam core, inherently provides excellent initial stability. With a hull speed of 10.35 knots, the Lagoon 620 is capable of respectable passage-making. Owners and reviewers note that the 620 handles well for its imposing size, particularly with features like newly developed rigs and potential in-boom furling systems designed to manage its large fully battened mainsail, making it more manageable for smaller crews. Under favorable downwind conditions with a gennaker, the boat can achieve speeds of 10 to 12 knots in 25 knots of wind.

Accommodations and Layout

The Lagoon 620 is renowned for its generous accommodations and flexible layout options, designed to offer a luxurious "superyacht character" for worldwide travel. The interior design often features elegant wood finishes and aims to maximize living space, both indoors and out, in line with Lagoon's design philosophy.

Typical layouts include various cabin configurations, commonly a 4-cabin, 5-cabin, or even 6-cabin version, with options for a lateral or central galley. Each cabin is designed as a VIP-sized space, often featuring a double bed and an en-suite bathroom with a separate shower and toilet, offering comfort comparable to a hotel. The owner's version frequently boasts a large master cabin with double access and direct access to the cockpit. The saloon is spacious, providing ample room for dining and lounging, and often offers panoramic views. The emphasis is on open, harmonious spaces between the interior and exterior, with large cockpits and expansive deck areas, including a flybridge that enhances exterior living and provides a commanding view for sailing. The finish quality generally utilizes composite materials and wood trim, ensuring durability and a sophisticated aesthetic.

Owner's Perspectives

Owners of the Lagoon 620 consistently praise its spaciousness, comfort, and robust build quality, which are hallmarks of the Lagoon brand. Many appreciate its capability for long-range cruising and liveaboard lifestyles, often highlighting the expansive interior volume and the seamless flow between indoor and outdoor areas. The various layout options are a significant draw, allowing owners to customize the vessel to their specific needs, whether for private use or charter.

While generally well-regarded for its comfortable motion and stability, some discussions among owners have touched upon the management of its large sail plan. Innovations like in-boom furling systems on later models have aimed to address the handling of the fully battened mainsail, though early systems might have experienced some initial "teething problems". The Lagoon 620 has proven its blue water capabilities, with one example taking third place in the ARC 2016 Multihull division. The overall sentiment is that the Lagoon 620 is a highly capable and luxurious platform for serious cruising, attracting owners who prioritize comfort and space on their voyages.
