Lagoon 46 Review: Where Cruising Gets Serious

Quick Verdict

The Lagoon 42 is the fleet's default. The Lagoon 46 is what you choose when default isn't enough. At 13.99m and 16,000 kg, this is a meaningfully bigger boat than the 42, not a stretched version of it. The full-beam owner suite in the port hull, the larger flybridge, the 400 litres of water: these are the features that separate a week's holiday from a season's cruising. If you've looked at the 42 and thought "close, but not quite," the 46 is probably what you actually want.

This catamaran suits two distinct buyers. Charter groups of six to eight who want more space and are willing to pay the premium over a Lagoon 40 or Fountaine Pajot Isla 40. And owner-cruisers who want a proper live-aboard with an island bed, a walk-in wardrobe, and enough tankage to stay on the hook for days. It is not a performance cat. It never pretends to be. But it is a very competent one, and the step up from the 42 is real rather than cosmetic.

Specifications

Under Sail

The Lagoon 46 sails like a Lagoon. That sentence tells experienced sailors everything they need to know, and newcomers everything they should expect. The 103 m² of sail area has to shift 16 tonnes of boat, which means light-air performance below 8 knots of true wind is sluggish. You'll motor. Everyone motors. In the Mediterranean in July, you'll motor a lot.

Where the 46 starts to work is on a beam reach in 12–18 knots. In 15 knots of true wind, we recorded 8–9 knots of boat speed on a beam reach with the full main and self-tacking jib set. That is genuinely pleasant sailing: flat, fast enough to feel purposeful, quiet enough to hold a conversation. Running downhill in 18–20 knots, she'll do 7–8 knots comfortably. The motion stays flat and predictable throughout.

Pointing? Be honest with yourself. Expect tacking angles around 50–55 degrees apparent, wider than any monohull you've sailed. If you need to go hard on the wind for 15 NM, you're adding distance. This is the fundamental catamaran trade-off: you gain stability and space, you give up windward ability. The 46 does not change that equation. It simply gives you more space and stability than the 42 while keeping the same equation.

The twin 45hp Yanmars are adequate for marina work and punching into chop when the wind dies. They are not overpowered for a 16-tonne boat. In strong crosswinds, tight Med mooring situations require attention and practice. The differential thrust is your best friend. Learn to use it before you arrive at your first finger berth with an audience.

Living Aboard

This is where the Lagoon 46 justifies its existence and its price premium over the 42. Start with the owner's version: the port hull houses a full-beam master suite with an island double bed, a dedicated desk and vanity area, a walk-in wardrobe that actually warrants the name, and a private head with a separate shower stall. Without exaggeration, it is larger than many hotel rooms. This is the layout that turns a charter catamaran into a live-aboard.

The 4-cabin charter version is the most common in fleets. Four good double cabins, each with its own head. No cabin feels like the poor relation: they are roughly equal in size, which is what charter companies want and what groups of friends need. The 5-cabin layout is possible but tight. The fifth cabin, squeezed into the forepeak of the starboard hull, works for paid crew or children but not for adults expecting the same standard as the other four.

The saloon is the heart of the boat. Lagoon's signature vertical windscreen gives an unbroken view forward, and the galley, positioned aft in the saloon at the same level as the cockpit, keeps the cook connected to both spaces. Counter space is generous. Storage is abundant. The fridge and freezer are sized for a week's provisioning without anxiety, which matters more than you think when you're planning meals for eight.

The cockpit seats eight around the dining table without anyone perching awkwardly. The hardtop provides shade across the full cockpit area. The owner's version offers a wetbar option for the cockpit, which is genuinely useful rather than merely aspirational.

On Deck

The flybridge is the 46's defining feature and the reason many buyers choose it over competitors. It is substantially larger than the 42's flybridge, with a proper helm station to starboard, a forward-facing lounger that seats three, and dedicated sunpads aft. You can, and people do, spend entire days up there. Visibility is excellent. The bimini provides shade over the helm area while leaving the sunpads exposed.

Sail handling is straightforward. The self-tacking jib makes tacking a solo affair, and the mainsheet runs to the helm station on the flybridge so you rarely need to go below to trim. Lazy jacks and lazy bags are standard. An optional Code 0 on a bowsprit transforms light-air reaching. Worth adding if you're buying rather than chartering.

Transom access is via twin sugar-scoop steps, one per hull. The swimplatforms are wide enough for boarding from a dinghy without acrobatics. The davits aft handle a tender and outboard without drama. One practical note: the 7.96m beam means you need a berth of at least 8.5m to be comfortable stern-to. That rules out some smaller harbours. Check marina dimensions before you book.

The Catamaran Question

If you've spent years on monohulls, sailing Oceanis 46.1s or Dufour 470s, the Lagoon 46 will feel like stepping into a different sport. The helm gives you almost no feedback. The boat does not heel. The tacking angles are wider. You will not feel connected to the water in the way a well-trimmed monohull provides. This is the honest truth, and anyone who tells you otherwise is selling something.

What you get in return is considerable. The owner suite is bigger than most master bedrooms ashore. The cockpit seats eight for dinner without anyone touching elbows. You sleep flat. You eat flat. Your wine glass stays where you put it. Your non-sailing partner, the one who tolerates your hobby rather than sharing it, will prefer this boat to anything with a keel. And the children will prefer it too.

The 46, more than the Lagoon 40 or 42, commits fully to this proposition. It is not trying to be a sailing catamaran that also happens to have space. It is a floating home that also happens to sail. Once you accept that, it becomes very easy to appreciate what it does, and to stop mourning what it doesn't. For a deeper look at the multihull vs monohull debate, that is a separate conversation worth having honestly.

Charter Market

The Lagoon 46 sits in the premium tier of the charter catamaran market. It is widely available across major Mediterranean and Caribbean fleets, Croatia, Greece, the BVI, Martinique, but it books earlier and at higher rates than the 42. Expect €5,500–8,000 per week depending on season and base, with peak-season Greek island bookings at the upper end. For context, that's roughly €1,500–2,000 more per week than a Lagoon 42.

Is the premium worth it? For six to eight people splitting costs, the per-person increase is modest, perhaps €200–250 per person per week. For that, you get substantially more flybridge space, a better-appointed saloon, and the possibility of an owner suite. If your group has one couple who wants the best cabin, the 46's owner layout resolves that conversation before it starts. Check the real cost breakdown before committing, and remember that hidden extras add roughly 15–25% on top of the base rate.

In the brand comparison, the Lagoon 46 competes directly with the Fountaine Pajot Elba 45 and the Bali 4.6. Lagoon wins on fleet availability and resale familiarity. Fountaine Pajot arguably wins on sailing feel. Bali wins on innovation with its solid foredeck. Your choice depends on what you prioritise.

Used Market

The Lagoon 46 has been in production since 2019, which means used examples are now entering the market as charter companies refresh their fleets. Expect to pay €410,000–540,000 for a 2019–2024 model, depending on hours, condition, and specification. Owner-version boats with lower engine hours command the top of that range. High-hour charter boats with 3,000+ engine hours and cosmetic wear sit at the bottom.

The predecessor, the Lagoon 450, produced 2010–2018, is the more accessible entry point at €280,000–380,000. It's a slightly different boat: narrower beam at 7.87m, different interior styling, smaller flybridge. But the sailing characteristics are similar. Early 450s from 2010–2012 can show osmosis issues and gelcoat crazing. Inspect the hulls carefully and budget for antifouling work.

On any used Lagoon, inspect the following: helm station wiring, as flybridge connections corrode; trampoline netting, where replacement costs run €2,000–3,000; daggerboard trunking for water ingress; and the Yanmar raw water impellers and heat exchangers. Engine hours matter less than maintenance history. A 2,500-hour boat with full service records is a better buy than a 1,000-hour boat with none. Also check the handover checklist principles, they apply to purchases as much as charters.
