The Best-Selling Cruising Catamaran: A Legacy of Comfort, Performance, and Over 1,000 Hulls Strong

Introduction & Design Heritage

In the competitive world of cruising catamarans, few models have achieved the iconic status of the one that stormed onto the scene at the Annecy boat show in 2015, entering production the following year. This vessel, succeeding the popular Lagoon 39, quickly became Lagoon's bestseller, with over 1,000 units produced and counting, cementing its place as a benchmark in the 40-45ft market. Designed by the renowned VPLP Design team—Van Peteghem/Lauriot-Prévost, long-time collaborators with Lagoon—the catamaran embodies a philosophy of blending spirited sailing performance with expansive, charter-friendly living spaces. Its sleeker lines, aft-pushed coachroof, and optional flybridge marked a generational leap, earning it prestigious awards like Sailing Today Multihull of the Year 2016 and Cruising World's Domestic Boat of the Year 2017. Built by Construction Navale Bordeaux (CNB) in France, this fourth-generation Lagoon design prioritizes short-handed ease, family cruising, and bluewater capability. Interiors by Italian studio Nauta Design flood the boat with natural light and openness, appealing to private owners and charter fleets alike. Though specific production figures beyond the 1,000+ milestone remain fluid as manufacturing continues today—with refinements in the 2020 Lagoon 42-2 update for better weight distribution and aesthetics—it has outshone rivals like Fountaine Pajot and Leopard models. For sailors dreaming of Mediterranean hops or Caribbean adventures, this catamaran's heritage promises a perfect fusion of adventure and luxury.

Construction, Technical Specifications & Design Analysis

At its core, the Lagoon 42 is a masterclass in modern multihull engineering. Measuring 42.1ft (12.80m) in length overall, with a generous 25ft (7.70m) beam and a shallow 4.1ft (1.25m) draft, it displaces 29,762lbs (13,500kg), offering stability without sacrificing agility. CE Category A Ocean-rated, it's built for serious offshore passages. The hulls employ vacuum-infused balsa-core fiberglass construction for decks and structures, with solid laminate below the waterline for durability and lightness—a choice that VPLP optimized for strength-to-weight efficiency. Key design signatures include vertical saloon windows for a sleek, contemporary look; twin aft-angled rudders for precise control; and a mast stepped further aft to minimize weather helm and enhance tacking. Upwind sail area stands at 1,292sqft, powering efficient performance. Options abound: standard coachroof helm, flybridge for panoramic visibility, or 3/4-cabin layouts, including owner's versions with a full-beam master suite. The 42-2 variant refines hull chines for improved hydrodynamics and subtle interior tweaks. Compared to its Lagoon 39 predecessor, it delivers better polars while retaining charter-optimized traits, making it a versatile platform against performance-oriented competitors.

Sailing Performance & Handling Characteristics

Sailors rave about the Lagoon 42's real-world prowess, particularly its short-handed friendliness. In 12-15 knots of breeze, it clips along upwind at 7-8 knots, thanks to the self-tacking jib and optional electric winches. Downwind, it surges to 10+ knots with ease, its wide beam and stability shrugging off swells. The aft mast position and rudders eliminate the slog of weather helm, allowing a couple to manage it effortlessly—ideal for family crews or liveaboards. Owners report exceptional roll resistance and seaworthiness, with CE A certification proven in Atlantic crossings shared on YouTube channels like Ruby Rose. It's no racing machine—average speeds lag pure performance cats—but excels in balanced, predictable handling. Flybridge versions offer superior visibility for docking or night watches, while the coachroof setup feels more intimate. In charter fleets, its forgiving nature shines, though heavy weather demands respect for its charter roots over radical speed.

Interior Layout & Comfort Features

Step aboard, and Nauta Design's influence dazzles: voluminous spaces bathed in light via hull windows and a galley-up saloon. The U-shaped galley boasts ample counter space, twin sinks, and a large fridge—perfect for provisioning. Saloon seating flows seamlessly to the cockpit, blurring indoor-outdoor boundaries with a sliding glass door. Cabins prioritize privacy: forward doubles with en-suites, and the owner's version claims the entire starboard hull for a king berth, desk, and sofa. Ergonomics shine in details like cockpit lounges, forward trampoline nets for lounging, and rigid bimini options. Headroom exceeds 6ft throughout, and storage abounds for bluewater gear. Drawbacks? Some note tight forward cabins in 4-cabin layouts for taller guests, but overall, it's a liveaboard haven. Natural ventilation via hatches reduces AC reliance, and teak accents add warmth without excess weight.

Engine, Propulsion & Technical Systems

Power comes from twin Yanmar diesels—standard 45hp, optional 57hp—paired with saildrives and fixed propellers for reliable motoring at 7-8 knots (fuel efficiency around 1.5-2 gph combined). Tanks hold 79 gallons fuel and 90 gallons water, extendable with options. Systems are charter-proven: 110V/12V electrical with inverters, solar-ready arches, and watermakers as popular upgrades. Davit systems handle dinghies up to 12ft, though corrosion watch is advised in saltwater. Rigging uses fractional sloop setups with Dyneema lines for low stretch. Maintenance is straightforward, with accessible engine bays, but high charter hours (check under 2,000 total) are key. Generators and lithium batteries feature in premium specs, ensuring off-grid comfort.

Ownership Insights: Market Value, Maintenance & Real-World Experience

The Lagoon 42's ownership appeal spans charter pros, families, and couples, with forums like CruisersForum and Reddit buzzing about its seaworthiness and comfort in rolly anchorages. Owners praise build quality—"solid as a rock," per one Ruby Rose voyager—abundant light, and galley functionality, though gripes include flybridge ladder steepness and davit rust in humid climes. Maintenance mirrors production catamarans: annual haul-outs for antifouling, rigging inspections every 5-7 years ($10k+), and sail replacements around 10 years. Resale holds firm; 2017-2019 models list at $500,000-$750,000 USD, buoyed by demand. Operating costs? $20k-30k/year for a couple, factoring insurance, storage, and upgrades. Practical advice: Insist on a thorough survey for delamination or osmosis; verify rigging/sails under 5 years; prioritize owner's versions for privacy; test helm feel upwind. It's stellar for Med charters or island-hopping but less for speed demons.
