The Lagoon 43 represents a significant evolution in the mid-range cruising catamaran market, specifically designed to succeed the incredibly successful Lagoon 42. Launched at the 2024 Cannes Yachting Festival, this model marks a shift in Lagoon Catamaran's approach to hull design and ergonomics. Developed through the long-standing collaboration between naval architects VPLP Design, exterior stylist Patrick le Quément, and interior specialists Nauta Design, the vessel emphasizes "easy movement" and indoor-outdoor connectivity. The most striking innovation is the integration of side access doors in the hull, a feature typically reserved for much larger yachts, which allows for effortless boarding from a dock without navigating the transom steps.

Sailing Performance & Handling
The Lagoon 43 is engineered for stability and ease of handling rather than raw competitive speed, maintaining a sail area-to-displacement ratio that favors comfortable passage-making. VPLP Design refined the hull shape to provide more buoyancy aft, accommodating the weight of modern cruising amenities while minimizing pitching in a seaway. The mast remains stepped relatively far aft—a signature Lagoon trait—which allows for a larger, high-aspect ratio self-tacking jib and a more manageable mainsail.
Under sail, the boat is designed to be operated by a couple, with all control lines led to a single raised helm station on the port side. While the high freeboard and voluminous hulls create significant windage, the inclusion of more powerful engine options (typically twin 57hp Yanmars) ensures reliable maneuvering in tight marinas. Editorial reviews from the vessel's debut highlight that the redesigned hull sections provide a smoother ride through chop compared to its predecessor, reducing the "slamming" occasionally felt in bridgedeck clearances of older designs.
Interior Comfort & Variations
The interior of the Lagoon 43 is defined by its modularity and the "open concept" pioneered by Nauta Design. A standout feature is the versatile dining arrangement; the saloon table is designed to move between the interior lounge and the aft cockpit, allowing the yacht to adapt to different social requirements or weather conditions. This "blurring of boundaries" is enhanced by a large window at the galley that retracts completely, creating a seamless service bar between the chef and the guests in the cockpit.
The vessel is offered in two primary configurations:
- The 3-Cabin Owner’s Version: This layout dedicates the entire starboard hull to the owner's suite, featuring a large island bed, a dedicated desk/vanity area, and an expansive forward head.
- The 4-Cabin Version: Primarily aimed at the charter market, this variant provides four symmetrical cabins and four heads.
Across both versions, Lagoon has increased the bed sizes compared to the Lagoon 42, ensuring that even the guest cabins feature wide berths with "semi-island" access, making them significantly more comfortable for long-term stays. The use of lighter oak finishes and increased overhead glazing ensures the interior feels airy and significantly larger than its 43-foot designation would suggest.
Popular Mentions & Media
As a brand-new release for the 2025 model year, the Lagoon 43 has been the subject of intensive coverage by the international yachting press, including featured walkthroughs by Yachting World and technical deep-dives in Multihulls World. It has quickly become the focal point of "New Era" discussions regarding catamaran accessibility, specifically cited for its innovative hull-side cutouts which are expected to set a new industry standard for mid-sized multihulls.
Known Issues & Buyer’s Checklist
Because the Lagoon 43 is a current-generation model, long-term structural data is limited. However, buyers and surveyors should focus on the following areas based on the model's specific innovations and Lagoon's historical build patterns:
- Hull-Side Door Seals: The new side-access doors are a point of mechanical complexity. Inspect the gaskets and locking mechanisms for watertight integrity and ensure the structural reinforcement around these cutouts shows no signs of stress crazing.
- Modular Furniture Tracks: The sliding table mechanism and the retractable galley window are moving parts subject to salt-air corrosion. Ensure these tracks are clean and the hardware operates smoothly without binding.
- Bimini Stability: On the raised helm station, check the rigid bimini or canvas supports for vibration. At cruising speeds or in high winds, these structures can occasionally resonance if not perfectly tensioned.
- Electronic Integration: Modern Lagoons rely heavily on digital switching (C-Zone or similar). Verify that the interface is responsive and that the manual overrides for critical systems (bilge pumps, navigation lights) are clearly labeled and functional.
Community & Resources
Owners of the Lagoon 43 benefit from the largest catamaran support network in the world. The primary hub for technical exchange is the Club Lagoon, an official manufacturer-sponsored platform that provides owners with access to specialized service manuals and a direct line to Beneteau Group parts. Additionally, the Lagoon Owners Association is a prominent independent group that organizes rallies and shares regional-specific maintenance advice for Lagoon sailors globally.
The Verdict
Pros:
- Revolutionary Access: The hull-side doors make the 43 the most accessible catamaran in its class for those with limited mobility or heavy gear.
- Living Volume: The "island bed" layouts and modular saloon/cockpit table offer the interior space of a 45-foot vessel.
- Ease of Use: A simplified sail plan and centralized helm make it an ideal choice for short-handed cruising families.
Cons:
- Windage: The high-volume hulls and tall coachroof make the boat susceptible to leeway in high winds during low-speed maneuvers.
- Weight: As a comfort-first cruiser, it lacks the light-wind performance of more performance-oriented (and more expensive) daggerboard catamarans.
- Complexity: Features like the retractable galley window and side doors add more maintenance points compared to traditional fixed-window designs.
