The Lagoon 46 represents a significant evolutionary step for the world’s most prolific catamaran builder, serving as the direct successor to the widely successful Lagoon 450. Launched in 2019, the 46 was tasked with bridging the gap between the mid-range cruisers and the larger luxury yachts in the Lagoon stable. Designed by the esteemed naval architects at VPLP Design, with exterior styling by Patrick le Quément and interiors by Nauta Design, the 46 is engineered to maximize volume and ease of handling. It is built using the manufacturer’s signature vacuum-infusion process, which optimizes weight-to-strength ratios, a necessity for a vessel with a light displacement of approximately 34,773 lbs. According to the official Lagoon 46 technical overview, the design prioritizes a "seaworthy and safe" platform that maintains the brand's DNA while introducing a more refined, contemporary aesthetic.

Sailing Performance & Handling
The most defining technical characteristic of the Lagoon 46 is the decision by VPLP to move the mast further aft compared to previous generations. This design choice, borrowed from racing multihulls, allows for a larger, higher-aspect-ratio self-tacking jib and a shorter, more manageable boom. In his assessment for Sail Magazine, reviewer Zuzana Prochazka noted that this configuration significantly simplifies short-handed sailing, as the smaller mainsail and larger headsail area create a more balanced sail plan that reduces weather helm.
While the Lagoon 46 is not a "performance" catamaran in the vein of carbon-fiber hulls, its sail area-to-displacement ratio is respectable for a heavy-displacement cruiser. On the water, the boat tracks well due to its deep fixed keels, though, like most cruising catamarans with this underwater profile, windward performance is limited to about 45 to 50 degrees off the true wind. Handling is centralized at the flybridge, which offers 360-degree visibility—a feature praised in Yachting World’s review for making Mediterranean-style berthing and close-quarters maneuvering far less stressful for the helmsman.
Interior Comfort & Variations
Lagoon’s partnership with Nauta Design is evident in the 46’s interior, which focuses on "gentle" luxury and horizontal lines to emphasize the sense of space. The boat is typically offered in two primary layouts: the three-cabin "Owner" version and the four-cabin "Charter" version. In the Owner configuration, the entire starboard hull is dedicated to a private suite, featuring a large island berth aft, a desk/vanity amidships, and a massive forward head with a separate walk-in shower.
The four-cabin variant provides symmetrical hulls, each with two en-suite cabins. A notable engineering feat is the lack of bulkheads encroaching on the berths; even the forward cabins feature island beds, a rarity in boats under 50 feet. The galley is U-shaped and positioned to serve both the interior salon and the cockpit seamlessly. Editorial testing by Cruising World highlighted the "seamless flow" between the aft cockpit and the salon, facilitated by a large sliding glass door and a window that retracts fully to connect the galley with the outdoor dining area.
Popular Mentions & Media
The Lagoon 46 has become a staple of the "digital nomad" and sailing YouTube community due to its liveaboard capabilities. It was notably featured as a flagship model during the 2019 and 2020 international boat show circuits, winning the "Best Multi-Hull Cruising Boat" (40 to 50 feet) award from several industry publications shortly after its debut. Its presence in high-end charter fleets across the Caribbean and the Mediterranean has further cemented its reputation as the benchmark for contemporary charter cats.
Known Issues & Buyer’s Checklist
While the Lagoon 46 is a robustly built production boat, there are specific areas potential buyers should investigate during a survey:
- Bulkhead Reinforcement: Following industry-wide discussions regarding bulkhead movement in earlier Lagoon models (primarily the 450), the 46 was designed with reinforced structural members. However, buyers should still commission a thermal imaging or moisture meter test of the main structural bulkheads, especially on hulls that have crossed oceans or been in heavy charter use.
- Flybridge Drainage: Some owners have reported that the flybridge drainage scuppers can become easily clogged with debris, leading to standing water near the helm electronics. Ensure the drainage paths are clear and the seals on the helm station instrument pod are intact.
- Hydraulic Platform Maintenance: If equipped with the optional Tenderlift hydraulic platform, the seals and hydraulic fluid levels must be checked annually. These platforms are subject to significant stress and saltwater exposure, making them a common point of mechanical failure if neglected.
- Rigging Tension: Due to the aft-stepped mast, the rig loads on the 46 are substantial. A professional rigger should inspect the chainplates and the tension of the diamonds to ensure the mast remains in column, particularly on newer boats where the initial "stretch" of the wire may have occurred.
Community & Resources
Owners of the Lagoon 46 have access to Club Lagoon, an official manufacturer-sponsored platform that provides technical manuals, service history tracking, and a community forum for verified owners. Additionally, the Lagoon Owners Association is an active independent group that organizes rallies and technical seminars, providing a wealth of shared knowledge regarding DIY maintenance and blue-water modifications specific to the VPLP-designed hulls.
The Verdict
The Lagoon 46 is a quintessential modern cruising catamaran that prioritizes volume, safety, and social space over raw speed. It is an ideal platform for families or couples intending to live aboard for extended periods.
Pros:
- Superior Layout: Island berths in all cabins and a dedicated owner's hull set the standard for the 45-50ft class.
- Ease of Handling: The aft-stepped mast and self-tacking jib make it one of the easiest catamarans to sail short-handed.
- Social Ergonomics: Excellent movement between the forward cockpit, the flybridge, and the aft deck.
Cons:
- Windward Performance: Like most heavy cruising cats, it struggles to point high and relies on engines in light air or tight upwind angles.
- Weight Sensitivity: Performance degrades noticeably when overloaded with heavy cruising gear, water-makers, and large tenders.
- Bridge Deck Slamming: In heavy, short-frequency head seas, the bridge deck clearance can lead to occasional slamming.
