The Lagoon 43 emerges as the latest evolution in cruising catamarans from the renowned French builder, Lagoon. Launched with a production start year of 2025, this catamaran is poised to succeed the immensely popular Lagoon 42, aiming to redefine comfort, space, and functionality within its class. With an overall length of 45.44 feet and a generous beam, the Lagoon 43 is designed to offer expansive living areas and capable performance for blue water cruising enthusiasts and those seeking relaxed onboard living. Its design, a collaborative effort featuring exterior styling by Patrick le Quément, interior design by Nauta Design, and naval architecture by VPLP Design, signifies Lagoon's commitment to blending aesthetics with practical seaworthiness.

The Lagoon 43 represents a significant step forward in the shipyard's lineage, taking over from the highly successful Lagoon 42, which saw over 1,150 units built. Its inception in 2025 continues Lagoon's tradition, stemming from its origins as a specialized division of Jeanneau Technologies Avancées (JTA), a high-tech, competition-focused arm of Jeanneau. This heritage imbues Lagoon with a foundational commitment to innovation and engineering excellence. The design philosophy behind the Lagoon 43 emphasizes maximizing living space, both indoors and out, with a focus on delivering vessels that prioritize "elegance, comfort, and reliability" for long-distance cruising and liveaboard lifestyles.

Patrick le Quément, a distinguished industrial designer, contributed to the exterior aesthetics, known for his ability to combine visual appeal with functionality. Nauta Design shaped the sophisticated interior spaces, ensuring a harmonious flow and luxurious feel. VPLP Design, Lagoon's long-standing partner in naval architecture, developed a new hull form for the 43 that dramatically increases interior volume without compromising performance. Notably, the Lagoon 43 introduces an additional aft entryway for each hull, enhancing accessibility, and features a large forward cockpit, a unique attribute for a catamaran of this size, providing more flexible outdoor living space.

Sailing Performance and Handling

Designed for reliable blue water performance, the Lagoon 43 aims to deliver stress-free sailing, even with a smaller crew. With a reported sail area of 1130.21 square feet (for the square top main option), the catamaran is equipped to harness the wind effectively. Reviewers have noted the Lagoon 43's lively sailing characteristics, observing steady progress at approximately 7.5 knots when closehauled in 18-19 knots of true wind.

The catamaran is fitted with twin keels and twin rudders, contributing to its stability and maneuverability. While specific performance ratios such as Sail Area to Displacement or Ballast to Displacement are not provided in the detailed specifications for this model, Lagoon's broader design ethos, often shaped by VPLP, typically emphasizes a balance between comfortable cruising speed and stability, suitable for a wide range of conditions encountered during offshore voyages. The redesigned hull shape by VPLP also contributes to improved hydrodynamic efficiency, enhancing its behavior in various sea states.

Accommodations and Layout

The interior of the Lagoon 43 benefits significantly from its innovative new hull form, which allows for notably generous interior volumes and larger berths in every cabin. The catamaran typically features four en-suite, air-conditioned cabins, each equipped with electric toilets and showers, alongside two additional smaller cabins, offering substantial flexibility for owners and charter guests alike.

Nauta Design's influence is evident in the sophisticated interior styling, which prioritizes maximizing living space and creating a seamless connection between indoor and outdoor areas. The owner's cabin, in particular, is noted for its fresh approach to traditional catamaran layouts, offering an innovative architectural design that provides enhanced comfort and space. The overall finish quality aligns with Lagoon's reputation for robust construction using fiberglass solid for both hull and deck materials, providing a durable and comfortable environment for extended cruising. Storage solutions are ample throughout, complementing the spacious layout designed for liveaboard comfort.
