The Lagoon 50 was introduced to the global market as a sophisticated bridge between the immensely popular Lagoon 450 and the larger, more complex Lagoon 52. Launched at the 2017 Cannes Yachting Festival, this model represented a significant shift in the brand’s design language, moving toward a more angular, modern aesthetic while incorporating technical refinements to the sail plan. Designed by the esteemed VPLP naval architecture firm, with exterior styling by Patrick le Quément and interiors by Nauta Design, the Lagoon 50 was specifically engineered to appeal to owners seeking a manageable large-scale catamaran that could be handled by a couple without the immediate need for professional crew.

Sailing Performance & Handling
The most defining technical characteristic of the Lagoon 50 is the placement of its mast, which is stepped further aft than on previous generations. This design choice, a direct influence from VPLP’s racing background, allows for a high-aspect-ratio mainsail and a larger, more efficient self-tacking jib. According to a detailed assessment by Sail Magazine, this configuration significantly reduces the physical effort required to tack and trim, as the smaller, narrower mainsail is easier to handle while the headsail provides a substantial portion of the driving force.
On the water, the Lagoon 50 is a cruising-oriented vessel that prioritizes stability and volume over raw speed. With a displacement of approximately 46,000 pounds (light ship), the boat feels planted and secure in a seaway. The flybridge serves as the nerve center for all sailing operations; all lines are led to a central winch pod, which provides excellent visibility of the four corners of the boat, though it does isolate the helmsperson from the social activity in the cockpit. While it may not point as high as a performance-oriented catamaran with daggerboards, its fixed keels provide a respectable balance of shallow-water accessibility and lateral resistance.
Interior Comfort & Variations
The interior of the Lagoon 50 is defined by an unprecedented level of modularity, designed to cater to both the private owner and the high-end charter market. The model is available in three, four, five, and even six-cabin configurations. In the three-cabin "Owner’s version," the entire starboard hull is dedicated to a massive master suite, featuring a walk-in closet, a desk, and a spacious head with a separate shower. The sibling variants, particularly the six-cabin layout, utilize the forepeaks and midships areas to maximize berthing, making it one of the most versatile platforms in its class.
The salon is characterized by 360-degree panoramic windows and a seamless transition to the aft cockpit via a large sliding glass door. A notable design evolution is the retractable sash window between the galley and the forward cockpit, which facilitates ventilation and allows the chef to interact with guests at the bow. Materials typically include Alpi wood finishes and heavy-duty Corian countertops, maintaining the brand's reputation for durable, sea-ready luxury.
Popular Mentions & Media
The Lagoon 50 quickly gained industry recognition following its release, earning the title of "Best Multihull Cruising Boat 40 to 50ft" in the 2019 Sail Magazine Best Boats awards. It has also become a staple of modern blue-water cruising media, featured prominently in several high-production-value YouTube sailing channels that focus on luxury liveaboard lifestyles. Its presence in major international charter fleets, such as those operated by Dream Yacht Charter and Navigare Yachting, has further cemented its status as a benchmark for contemporary multihull design.
Known Issues & Buyer’s Checklist
When inspecting a pre-owned Lagoon 50, prospective buyers should focus on the specific structural and mechanical areas common to large production catamarans.
- Rigging Tension and Mast Step: Given the aft-stepped mast, the rig puts different stresses on the deck structure than traditional layouts. Check for any compression cracks or signs of movement around the mast foot and the supporting pillars in the salon.
- Engine Access and Maintenance: The Lagoon 50 is typically powered by twin Yanmar engines (either 57hp or 80hp). Because these are located in the aft compartments of the hulls, check for signs of moisture or salt spray intrusion through the deck hatches, which can lead to premature corrosion of the sail drive units.
- Flybridge Gelcoat: The large horizontal surface area of the flybridge is prone to UV degradation. Look for "crazing" or spider cracks in the gelcoat, which may indicate excessive flexing or sun damage.
- Bulkhead Inspection: While Lagoon significantly updated their construction techniques for this generation, any large catamaran should be inspected for bulkhead tabbing integrity, particularly if the vessel has a history of heavy offshore use or charter service.
Community & Resources
Owners of the Lagoon 50 benefit from one of the most robust support networks in the marine industry. The Lagoon Owners Association provides a wealth of technical data and modification tips specific to the 50-foot platform. Additionally, the Lagoon Catamarans official website offers technical manuals and a dedicated "Club Lagoon" portal for parts ordering and factory support. For technical discussions and vendor-neutral advice, the "Lagoon Owners Group" on various social platforms is considered the primary hub for real-time troubleshooting.
The Verdict
The Lagoon 50 is a masterclass in maximizing liveable volume without sacrificing the essential safety characteristics of a blue-water cruiser. While its sheer windage and weight mean it will never be a racing machine, its innovative rig and expansive social spaces make it one of the most comfortable "home-on-the-water" options available today.
Pros:
- Exceptional interior volume and headroom in all cabins.
- The aft-stepped mast makes for an easily managed sail plan for short-handed crews.
- Highly modular layouts ranging from three to six cabins.
- Excellent bridge deck clearance which reduces slapping in heavy seas.
Cons:
- The flybridge helm can feel isolated from the main cockpit and salon.
- High windage can make docking challenging in strong crosswinds.
- Heavy displacement limits light-wind sailing performance without a Code 0 or Gennaker.
