Lagoon 450S

Performance, Beauty and Refinement

The Lagoon 450 SporTop is super impressive, featuring an easy communication between the crew and the skipper.

The Lagoon 450S caters for boaters who wish to enjoy the comfort of a catamaran of 45 feet in a more conventional version, with a helm post on the bulkhead in place of the flybridge.

Delivering sleek and effortless elegance, xwith a lower rig reducing pitch and providing better access to the boom, yet the mainsail area is maintained.

Once again Nauta Design Studio has created an interior that is all elegance and functionality. 

The exceptional saloon and cabins are bathed in natural light, thanks to large glazed panels on the hulls.

Relax in style in the truly luxurious owners’ cabin … and if you’re a guest on this gorgeous Lagoon, the guest cabins are equipped with double beds with side access.

A U-shaped galley means greater comfort at sea … and is equipped with large hot plates, broad work space and plenty of storage.

With the Lagoon 450S, the French builder has taken a proven concept and incorporated subtle changes to produce a cat that’s easy to operate.

All the running rigging, including the overlapping genoa’s sheets and traveller, are also right there, organised in conjunction with a trio of Harken electric winches and a suite of Spinlock clutches.

As I said before, over 500 Lagoon 450 Flybridge versions were produced. So this model has already proven itself to be a good ocean cruiser in various ocean crossings and rallies like the ARC Rally. Bearing in mind that the 450S is not a performance catamaran, we were pleasantly surprised with her performance under all conditions.

“19 days! Maybe not a “Route du Rhum” time, but nevertheless a very creditable performance for a voyage from La Rochelle to Pointe à Pitre (3477 miles) in a strictly standard Lagoon 450.”

Jean-François Tanguy, professional skipper – February 2011

“The sail plan gives the boat enough power to remain fast and dynamic in a wind of less than 10 knots.”
