Design and Construction
The Sixty 5 is the sailing iteration of the Sixty 7 power catamaran. Unusually, the motor yacht served as the base model rather than the sailboat, as Multihulls World noted in its review.
Lagoon retained the design language of its larger catamarans, including the suspended deckhouse and the distinctive “ear” cut from the top of each aft pillar. Above the waterline, the coachroof has the familiar turret-style brow associated with the marque. A straight stem at the bow maximizes waterline length, while an integrated bowsprit gives the bow a clean leading edge. Teak decks—unusual on a catamaran—add a classy touch.
Both the hull and deck use balsa-cored laminates, with polyester and vinylester resins in the layup. The aft third of the hulls, along with the rudders and keels, received specific development work to adapt the power platform for sailing.
The Sixty 5 measures 20.55 m overall and 10 m across the beam. Light displacement is 39.2 tonnes, draft is 1.6 m and air draft is 33.9 m.
Rig and Handling
The yacht carries 272 m² of sail upwind, signaling a serious offshore rig rather than one intended for coastal weekends. The 168 m² full-batten mainsail is paired with a 102 m² roller-furling genoa. A triple-headsail arrangement lets the crew change gears as wind strength and direction shift, while an optional 150 m² Code 0 adds more light-air sail area. During a test sail in middling conditions, the boat made a solid 5 knots under the Code 0 in just 7 knots of wind.
The flybridge is the yacht’s pièce de résistance. Set high above the water, it has twin helms flanked by comfortable upholstered bench seats, with engine controls and chartplotters close at hand. Four Harken winches sit beneath a solid overhead Bimini. The traditional mainsail is controlled by a continuous-line traveler led back to those winches.
A second, indoor steering station in the saloon is controlled through the B&G autopilot, giving the crew another option in poor weather.
Living Spaces and Accommodations
Nauta Design created an interior built around open spaces and natural light, with views directed toward the horizon. Alpi-finished woodwork and refined upholstery give the space an elegant feel.
Owners can choose four, five or six staterooms, and sleeping capacity ranges from eight to sixteen people. The galley may be installed on the saloon level or down in a hull, while the owner’s staterooms are sumptuous. Separate crew quarters accommodate a captain, chef and mate.
Outside, a forward cockpit provides space for lounging or reading. The aft cockpit adds more seating and a dining area. The flybridge has its own galley, equipped with a fridge, sink, ice maker and Kenyon grill, plus enough seating to serve as a waterborne café.
CE approval is A:14, B:18, C:24, D:40.
Engines, Systems and Tankage
Published sources differ on standard engine power. The Sailboat Review test report identifies standard propulsion as a pair of 150 hp Yanmars, while the manufacturer also lists a standard 195 hp rating and an option for twin 195 hp. The test boat had been upgraded to twin 195 hp diesels with Flexofold props.
Two gensets are fitted. One supplies general house loads, while the other is dedicated to the individual air-conditioning units. Fuel capacity is 1,300 L and water capacity is 1,000 L, supporting long, independent passages. The flybridge helm is fully equipped with current cruising technology.
Ownership Profile
Lagoon has been building roughly 20 Sixty 5s per year. All have gone to private owners rather than charter fleets.
This is a great deal of boat to handle, and nearly all owners employ a captain, chef and mate. Many offset some of the expense by making their yachts available with full crews for five to ten weeks each year.
The Verdict
The Lagoon Sixty 5 is a thoroughly modern expedition catamaran that turns a power-platform hull into a capable sailboat without compromising volume or finish. Its flybridge command center, flexible stateroom arrangements and dual-genset system suit owners who cruise with professional crew. At the same time, the triple-headsail rig and reported light-air performance help keep the boat lively when the breeze fades.
This isn’t a short-handed boat. As a private, full-service bluewater platform, however, it is difficult to fault.
