Lagoon 46 Sailboat Review, Specs, and Listings

Design and Construction

Lagoon built the 46 in Belleville-sur-Vie, France, using vacuum-infused balsa coring above the waterline to keep weight low while preserving structure. VPLP introduced pronounced chines that flare outward just above the waterline, and those chines considerably add to the living space in each hull without disturbing the narrow underwater form. The wraparound glazed vertical windows look continuous but are made of separate panels, and the rectangular hull ports are larger than those on the 450, flooding the guest cabins with light. Below the sole, blackwater tanks for all heads are mounted rather than on the hull side, lowering the center of gravity. The coachroof carries a handhold molded directly into the GRP instead of stainless rails, and the engine-room hatches open aft for access. Reconstituted Alpi wood interiors, with a choice of three finishes including a darker brown and optional leather accents, furnish the saloon and cabins.

Rig and Handling

The mast is stepped relatively far aft to minimize hobbyhorsing, and the shorter boom is more manageable while the higher-aspect rig captures winds aloft. A self-tacking jib on its own track works with the square-top main, and an optional Code 0 of 105 square meters extends the boat’s range off the wind. The visible furling boom lets the crew watch reefing and furling directly rather than guessing behind a cover. A recessed electric Harken winch drives the continuous main traveler, and offset-to-port winches gather all sail-control lines to the skipper. On the flybridge the wheel is offset to port, and the two aft hardtop supports double as ladders to the mainsail bag, though testers found those ladders as awkward and slick as on the 50. In 15 knots true on the beam, expect 9 to 10 knots in minimal chop; with the Code 0 in 18 knots, 11 to 12 knots is possible. Twin 57 hp Yanmar diesels with saildrives pushed the test boat to 8.5 knots wide open and a friendly 7 knots at 2,200 rpm.

Accommodations

The cockpit affords an exceptional horizon view and is a modular living space with generous storage, sliding bench seating, and an exterior galley to starboard with sink, fridge, and bottle cutouts; it seats up to twelve. A folding port table serves a quick breakfast or dinner for eight, and a forward sliding seat reveals steps to the port side deck. The saloon and galley sit on the same level, with a center forward window that slides down to the foredeck and a nav desk to port. The flybridge transforms between sundecks and a full helm station with a long bench for skipper and three, a triple-wide sun pad, and an angled dash carrying MFD, wind, autopilot, and windlass remote. The three-cabin owner layout places a queen island berth aft in the starboard hull, an elongated settee and desk amidships, and a forward head large enough for two with a separate toilet compartment. A four-cabin, four-head charter layout with separate showers is also available, and berths run from six to twelve persons across four to six cabins.

Known Issues

The hardtop aft support ladders are awkward and slick, a handling hazard when managing the main at sea. With a mast height of 76 feet, the 46 cannot transit the ICW, a hard limit for inland passage.

The Verdict

The Lagoon 46 refines the successful 450 formula with lower weight, aft-moved rig, and expanded hull volume through flared chines. It sails and motors with poise rare in the class, though the mast height bars inland passage and the flybridge ladder design needs care. For owners wanting charter-grade space with shorthanded ease, it is a benchmark coastal and bluewater cruiser.
