The successor to the Lagoon 450 — a 45-foot 10-inch cruising catamaran in current production since 2019. Modern systems, refined interior, and improved sailing performance over the outgoing 450, with the proven Lagoon ownership ecosystem behind it. Available in 3-cabin owner and 4-cabin charter layouts.
The Lagoon 46 entered production in 2019 as the direct replacement for the long-running Lagoon 450. Designed by VPLP with interior styling by Nauta Design and Patrick le Quément, the 46 was built around a clear brief: refine the proven 450 formula without abandoning what made the outgoing model the best-selling 45-foot catamaran of its decade. The result is an evolutionary update rather than a revolution — same fundamental layout philosophy, modernised execution.
What the 46 changed: modern systems integration (the 450 came from a pre-touchscreen era; the 46 reflects current expectations for digital chartplotters, NMEA 2000 networking, and integrated cabin controls), refined interior finish (more contemporary materials, better light, improved galley layout), and incrementally better sailing performance through hull refinements, a slightly more efficient rig, and weight reduction in select systems. What it kept: the proven flybridge layout, the 3-cabin and 4-cabin layout options, and the simple-and-durable systems philosophy.
For buyers, the 46 occupies a clear position: the modern alternative to the 450. Where the 450 is the value play with charter-history caveats, the 46 is the turnkey buy at a 35 to 50 percent premium. Charter-fleet exposure exists but is meaningfully lower than the 450 — many 46s are still on first ownership, and the resale pool skews toward private-use rather than ex-charter. For buyers wanting modern systems and a boat that won't need €25k to €60k of post-purchase remediation, the 46 is the better choice. For buyers prioritising value, see our Lagoon 450 page.
Specifications are manufacturer figures for a base specification Lagoon 46. Individual boats vary based on year, equipment, and owner modifications. Always verify against the specific boat's documentation during survey.
The Lagoon 46 is offered in two distinct layouts. As with all Lagoon production models, the layout decision is the most important choice in a 46 purchase, meaningfully affecting price, resale, and how the boat actually lives.
The starboard hull is dedicated to a single owner suite with island king-size berth, large head with separate shower, walk-in storage, and dedicated workspace. The port hull contains two guest cabins with a shared head. Total of 3 cabins, 2 heads. Best for couples cruising with occasional guests, liveaboards, and any owner who doesn't need maximum sleeping capacity. Trades at a 12 to 18 percent premium to charter version on the resale market.
Both hulls split symmetrically into two cabins each, with four heads (one per cabin). Total of 4 cabins, 4 heads. Sleeps up to 8 guests plus crew in saloon. Designed for charter operations, family use with multiple children, or owners who frequently host guests. Lower per-cabin price but reduced storage. The dominant layout in charter fleets but a smaller share of the 46's resale market than the 450's.

Browse all Lagoons →Charter-version 46s commonly show 2,500 to 4,500 hours by year 5; owner-version typically 600 to 1,500 hours over the same period. The Yanmar 4JH57 is a proven engine but service intervals matter — oil and filters at 250 hours, valve clearance at 1,000 hours. On a 5-year-old charter 46, expect to see at least one major service completed; missing service history is a price negotiation lever of €5,000 to €10,000.
Yanmar SD60 saildrive seals need replacement every 5 to 7 years. On a 2019-2020 charter 46 still on original seals, this is now overdue and a near-certain €4,000 to €7,000 job per side. On a 2022+ boat, original seals are likely still serviceable but should be inspected. Check gear oil for any milky appearance indicating saltwater intrusion — that's an immediate haul-out.
Charter-fleet 46s are typically on second sail wardrobes by year 5. Standing rigging on 5+ year-old 46s should be inspected for surface corrosion, swage condition, and chainplate seal integrity. New main and genoa together: €15,000 to €22,000. Lagoon 46 chainplates have shown better long-term sealing than early 450s, but don't skip the inspection.
The Lagoon 46 came factory-equipped with NMEA 2000 networking, integrated Raymarine or B&G electronics, and digital cabin controls. Test every system live — chartplotters, autopilot, AIS, radar, depth, wind, and any integrated cabin lighting or audio. Charter boats are particularly prone to dead pixels and degraded chartplotter screens after 4-5 years of sun exposure. Comprehensive electronics refresh: €8,000 to €18,000.
Air conditioning compressors, watermakers, generators, and washer-dryers all see heavy charter use. Onan or Fischer Panda generators typically show 1,500 to 3,000 hours on a 5-year-old charter 46 — service records and oil analysis are essential. Watermaker membranes have a 5-year life; replacement is €1,500 to €3,500. Charter 46 house systems frequently need €5,000 to €15,000 of catch-up after purchase.
The Lagoon 46's interior is more refined than the outgoing 450 but charter use still produces meaningful wear by year 4-5. Upholstery, headliner, and galley surfaces are the typical wear points. Cosmetic refresh on an ex-charter 46 typically runs €10,000 to €25,000 depending on scope — less than the older 450 because the 46's interior is newer, but not nothing. Owner-version 46s typically need only minor refresh.

Used Lagoon 46 prices typically range from €580k for an early 2019-2020 charter-version, up to €880k for a recent 2023-2024 owner-version with full equipment. New Lagoon 46s start at approximately €850k for base specification, rising to €1.1M and above with the typical owner equipment package. Charter-version 46s typically trade 12 to 18 percent below owner-version equivalents.
The Lagoon 46 (2019-present) is the direct successor to the Lagoon 450 (2010-2019). Both are 45 to 46-foot cruising catamarans with similar interior volumes. The 46 has modern systems including upgraded electronics integration, more refined interior finish, slightly improved sailing performance through hull and rig refinements, and current production support. The 450 is older, more interior volume per dollar on the resale market, but heavily charter-worn.
The Lagoon 46 is widely considered one of the best 45-foot cruising catamarans in current production. It refined the proven Lagoon 450 formula with modern systems, slightly better sailing performance, and improved layout flow without abandoning what made the 450 successful. Strengths include genuinely spacious owner-version layout, well-developed flybridge with practical helm position, modern electronics integration, and strong resale liquidity.
The Lagoon 46 is offered in two layouts. The 3-cabin owner version dedicates the entire starboard hull to a single owner suite with king-size berth, large head with separate shower, walk-in storage, and dedicated workspace. The 4-cabin charter version splits both hulls into two cabins each, with four heads, designed for charter guest capacity of up to 8 guests plus crew. The owner version sells for a 12 to 18 percent premium on the resale market.
Direct competitors in the 45 to 50-foot bracket. The Lagoon 46 prioritises interior volume, modular layouts, and the proven Lagoon ownership ecosystem. The Fountaine Pajot Saba 50 is slightly larger at 50 feet, offers sharper sailing performance and a more refined interior finish, and tends to attract more private-owner buyers. Pricing is comparable for similar-age boats. Charter-fleet exposure favours the 46 (more available on resale); private-owner inventory tends to lean Saba.
Yes — the Lagoon 46 is regularly used for Atlantic crossings, including ARC and other organised transats. With proper preparation, the 46 is a competent ocean-cruising catamaran. The boat is conservative rather than fast — typical Atlantic crossing times are 16 to 22 days, comfortable rather than thrilling. For high-latitude or Pacific cruising, performance-oriented brands like Catana, Outremer, or HH Catamarans are better suited.
