Lagoon Seventy 7 Information, Review, Specs

History and Design

The creation of the Lagoon Seventy 7 in 2017 marked Lagoon's most significant project to date, following the success of models like the Lagoon 620 and 630. Lagoon's core ambition was to imbue the Seventy 7 with the "DNA of a superyacht," visually signaling a relentless pursuit of excellence in its design. This vision brought together an illustrious design team: VPLP Design, long-standing naval architects for Lagoon, contributed to the catamaran's hydrodynamic efficiency; Patrick le Quément shaped her distinctive and elegant exterior lines; and Nauta Design crafted the sophisticated interior spaces.

As a specialized arm of Jeanneau Technologies Avancées (JTA), Lagoon Catamaran was founded with a commitment to innovation and engineering excellence, a philosophy that continued to define its approach to the Seventy 7. This heritage, later strengthened under the Beneteau Group, emphasizes the use of advanced composite materials for durability and robust performance. The Seventy 7, consistent with Lagoon's ethos, focuses on maximizing living space, comfort, and safety, making it an ideal long-distance cruising vessel. During its production run, the Lagoon Seventy 7 has offered various layout options, including 3, 4, and 5-cabin versions, with additional customisation possibilities such as integrating a conference room, games room, or even a cinema, allowing owners to tailor the yacht to their specific desires.

Sailing Performance and Handling

With a length overall of 78.22 feet (23.77m) and a waterline length of 75.62 feet, the Lagoon Seventy 7 commands a significant presence on the water. Boasting a reported sail area of 3609.0 square feet and a mast height of 125.33 feet from the waterline, she is designed to harness the wind effectively. Weighing in at a displacement of 139,658 pounds, this large catamaran is built for stability and comfortable motion.

While performance ratios are less applicable to catamarans of this size, owner and reviewer feedback consistently praises the Seventy 7 for its "flawless performance" and "smooth sailing performance". It is described as having impressive long-range capabilities, designed for maximum safety and comfort in all conditions. The ability to deploy a Code Zero sail further enhances its performance in lighter wind conditions. Propulsion is typically provided by twin diesel engines, with options including Volvo Penta 175hp units or twin John Deere N5 230hp engines, providing ample power for maneuvering and motoring.

Accommodations and Layout

The interior of the Lagoon Seventy 7 is a hallmark of its design, prioritizing expansive living spaces, natural light, and luxurious finishes. Nauta Design's contribution ensures an elegant interior aesthetic with a focus on harmony between indoor and outdoor areas. The yacht offers a variety of highly customizable interior layouts, including owner's, VIP, and guest configurations, allowing for a personalized onboard experience.

Common arrangements include a spacious salon with panoramic views, complemented by large cockpits and extensive deck areas that define Lagoon's design philosophy of maximizing comfort and volume. While specific headroom details are not always listed, the generous dimensions of a vessel of this size ensure ample standing room throughout. Depending on the chosen layout, the yacht typically features multiple cabins and bathrooms, with examples including 4-cabin, 4-bathroom configurations. The owner's suite, often positioned aft, can feature direct access to the sea and integrate with a crew cabin or galley in some configurations, creating dedicated zones for owners and guests. Throughout the vessel, the finish quality reflects high-end features and sophisticated use of materials, providing a truly luxurious cruising environment.
