The Lagoon 42 represents a defining moment in the evolution of cruising multihulls, successfully bridging the gap between the mass-market appeal of its predecessor, the Lagoon 421, and the high-performance design cues inherited from VPLP’s racing pedigree. Launched at the 2016 Düsseldorf Boat Show, this model was designed by VPLP Design in collaboration with Patrick le Quément for the exterior and Nauta Design for the interior. It quickly became one of the fastest-selling catamarans in history, surpassing the 1,000-unit milestone within a few years of its debut. The boat serves as a middle-ground centerpiece in the Lagoon range, sitting between the more compact Lagoon 40 and the larger, flybridge-equipped Lagoon 46. Unlike its predecessor, which featured more angular lines, the 42 introduced a more curvaceous, organic silhouette and a revolutionary rigging plan that moved the mast further aft to improve balance and handling.

Sailing Performance & Handling
The most significant technical departure in the Lagoon 42 is its mast position. By stepping the mast further aft, designers were able to utilize a larger, high-aspect mainsail and a self-tacking jib, which dramatically simplifies short-handed sailing. According to editorial testing by Sail Magazine, this configuration reduces pitching in a seaway and allows for a shorter, more manageable boom. While the 42 is fundamentally a cruising catamaran with a relatively high displacement-to-length ratio, its performance in light-to-moderate air is surprisingly nimble for its class.
The boat’s handling is characterized by its centered weight distribution, which minimizes the "hobby-horsing" effect common in older multihull designs. The helm station is located on a raised mid-port position, offering excellent visibility of all four corners of the vessel—a critical factor for docking and close-quarters maneuvering. Technical reviews from Yachting World highlight that while the self-tacking jib limits performance when sailing deep downwind, the optional Code 0 or a parasailor becomes an essential addition for long-distance cruising. The steering is cable-driven, providing more feedback than hydraulic systems, though it remains a "dampened" experience compared to performance-oriented cats like an Outremer.
Interior Comfort & Variations
The interior of the Lagoon 42 is the product of Nauta Design’s focus on light and "flow." The salon and cockpit are nearly on a single level, connected by a massive sliding glass door that erases the boundary between indoor and outdoor living. The boat was primarily produced in two configurations: the three-cabin "Owner’s version" and the four-cabin charter layout. In the three-cabin variant, the entire starboard hull is dedicated to a master suite featuring a large island bed, a desk/vanity area, and a cavernous forward head with a separate shower stall.
A standout feature discussed in the Lagoon 42 Technical Brochure is the use of large hull glazing, which provides panoramic views from the berths that were previously only seen in much larger yachts. The "island bed" design in the aft cabins allows for easy access from both sides, a luxury rarely found in 40-foot multihulls. Materials typically include Alpi wood veneers (often light oak or walnut), which are durable and weight-efficient. Sibling models include the Lagoon 420 and 421, which used the same length profile but featured much heavier hulls and less efficient rigs; the current 42 is widely considered a superior sailing platform in every metric.
Popular Mentions & Media
The Lagoon 42 has gained substantial cultural traction within the "sail-vlogging" community, most notably through the YouTube channel Tula’s Endless Summer. Their extensive voyages aboard a Lagoon 42 have provided thousands of prospective buyers with real-world data on the boat’s durability and liveaboard capacity. Additionally, the model earned the prestigious "Boat of the Year" award from both Cruising World and Sail Magazine upon its release, cementing its status as a benchmark in the industry.
Known Issues & Buyer’s Checklist
While the Lagoon 42 is a robustly built production boat, there are several high-signal areas that secondary market buyers must investigate.
- Bulkhead Reinforcement: There has been significant discussion within the owner community regarding the structural bulkheads on certain hulls produced between 2016 and 2021. Lagoon issued a technical bulletin and a reinforcement program to address potential movement in the forward and main bulkheads under high rig tension. Buyers should verify if a specific hull was part of this "reinforcement campaign" and ensure the work was performed by an authorized yard.
- Rudder Bearings: Like many Lagoon models, the 42 can experience premature wear of the self-aligning rudder bearings. During a survey, the rudders should be checked for excessive lateral play, which can lead to a "thumping" sensation at the helm.
- Escape Hatches: Early units were fitted with Goiot escape hatches that were subject to a safety recall due to adhesive failure. Ensure the hatches have been replaced or are the updated "bolted" versions.
- Bimini Stress: The composite hardtop bimini is a heavy structure supported by stainless steel pillars. Inspect the mounting points for stress cracks in the gelcoat, which may indicate the boat has been pushed hard in heavy seas.
Community & Resources
The Lagoon 42 benefits from one of the most organized owner networks in the maritime world. Club Lagoon is the official manufacturer-sponsored portal providing technical manuals and direct access to spare parts. On a more grassroots level, the Lagoon Owners Group (LOG) is a highly active technical forum where members share DIY fixes and modification plans. For technical specifications and original design intent, VPLP Design maintains a portfolio page detailing the naval architecture of the hull and the evolution of the rig.
The Verdict
The Lagoon 42 is arguably the most successful "condominium-style" catamaran ever built, offering a level of volume and ergonomics that redefined the 40-to-45-foot class. While it is not a "daggerboard" performance cat, its updated rig makes it a much more capable sailor than the Lagoon models of the previous decade.
Pros:
- Exceptional Ergonomics: The single-level flow from the helm to the cockpit and salon is best-in-class.
- Ease of Handling: The aft-stepped mast and self-tacking jib make it one of the easiest 40+ foot boats to sail solo.
- Resale Value: Due to its massive popularity, the Lagoon 42 remains one of the most liquid assets in the used boat market.
Cons:
- Bulkhead Concerns: Prospective buyers must do their due diligence regarding the structural reinforcement history of the vessel.
- Weight Sensitivity: Like all cruising cats, performance degrades significantly if overloaded with heavy aftermarket equipment (large battery banks, heavy tenders, etc.).
- Bridge Deck Slamming: In short, choppy seas, the bridge deck clearance can result in occasional "slapping," though this is less pronounced than on the older 421 model.
