Design and Construction
The 2021 Lagoon 55 carries imposing topsides with taut lines, sculpted bows, and a pronounced lower chine that maximizes interior living space yet minimizes wetted surface area anchor. Access aboard is eased by sugarscoop transoms that extend beyond the topsides, and once aboard, two steps lead up to a cockpit flush-decked with the aft platform. Circulation is a clear design priority: with the mainsheet track moved to the bimini, the aft beam disappears, freeing both the view and the options for moving around as a real terrace on the water. The forward cockpit is no longer dug into the foredeck but integrated seamlessly on the same level as the trampoline, with comfortable seating, two sun-protection options, and communication to the interior through the opening front window.
Rig and Handling
The mast has been moved aft in keeping with current trends, and at its foot all sailing maneuvers are carried out using three winches, while the mainsail is hoisted and the self-tacking genoa unfurled with ease by a single crewmember. A self-tacking jib keeps sheets led to a track on the coachroof just ahead of the mast, and a sprit with an electric furler hosts a code zero. Three electric winches handle all sail-control lines except the traveler, which is adjusted by an electric continuous-line winch with nearby push-button controls. An optional rigid bimini raises the boom considerably, compelling the crew to undertake some challenging maneuvers. Under power at a cruising 2,000 rpm the boat showed about 9 knots on the GPS, though steering seemed a bit sluggish both motoring and under sail anchor, with the self-tacker set she moved closehauled at about 6 knots and gained another knot and a half on a beam reach. A 154m² Code 0 allowed 5.5 to 6.5 knots with wind on the beam, and under a 272m² asymmetric spinnaker she averaged 5.5 knots before returning upwind at 5 knots. The works crew claimed 8- to 9-knot average speeds on their European tour.
Accommodations
The flybridge places the helm station there, with the wheel offset to starboard giving a very good 270° view for maneuvering off a pontoon. Steps to either side ensure good traffic flow, and abaft the helm a sink and fridge sit alongside a U-shaped seating area around a low cocktail table. Forward and aft sunbathing areas and an outdoor galley round out the flybridge. Below, the cockpit holds two starboard tables with unfolding tops to seat a crowd, plus cushioned lounges facing aft. The swim platform doubles as a raised balcony over the water or, lowered, a place to sit with feet in the water. A forward U-shaped seating area sits directly ahead of the cabin house, and the saloon's center window opens to pass refreshments out to those seated there.
Inside, the hulls allow all guest berths to be laid athwartships, and the boat offers four, five, or six stateroom layouts with berths for up to 16; the owner may choose the galley up or down. The four-cabin version places the owner's cabin aft in the starboard hull occupying two-thirds of that hull, with the other three cabins each en-suite. Joinery and materials recall the atmosphere aboard Lagoon's Sixty 5 and Seventy 7, with an L-shaped starboard galley extended by a bar unit, a large U-shaped saloon settee, a telescopic table, and stowage from floor hatches to bookshelves.
Ownership Notes
The tested boat carried a pair of upgraded 115 hp Nanni engines with saildrives, while 80 hp diesels are standard, and a suite of B&G electronics was fitted. A cloth sunshade over the forward seating area was held by removable carbon-fiber poles. A second starboard-side-deck access to the flybridge is available as an option not fitted on the test boat, avoiding further acrobatics otherwise needed.
The Verdict
The 2021 Lagoon 55 is a head-turner dockside that will pamper owners and crew alike, synthesizing volume, circulation, and single-handed sail handling into a high-end cruising platform. The chined hull and flush cockpit terrace make the most of a 29.5-foot beam and the fully-laden 33 tonnes, while the flybridge helm and athwartship berths show a considered approach to livability. Sluggish steering and a high boom over the rigid bimini are the trade-offs a buyer accepts for that comfort.
Pros
- Pronounced lower chine maximizes interior space while cutting wetted surface
- Self-tacking jib and three winches let one crewmember handle the sail plan
- Flybridge helm with 270° view and offset wheel aids close-quarters maneuvering
- Up to six staterooms with athwartship berths and owner's two-thirds hull cabin
Cons
- Steering feels sluggish both under power and sail
- Rigid bimini raises boom, making sail maneuvers awkward
- Standard 80 hp diesels may feel modest against the loaded displacement
