S/V Antares is a very well maintained 2018 Lagoon 450 Flybridge catamaran, for sale by owner. Very recent engine survey available upon request.

Engine cylinders have excellent compressions. Starts right up and purr like kittens. Good oil analysis results for both engines and generator. New engine batteries and generator battery. New trampoline.  New bimini top in the works.  Was taken out of the water in November 2023, checked out, scraped the bottom and painted .  Import tax paid.

New wind instrument transducer. Very comfortable queen size beds. New dinghy with 8.0 HP outboard included in the sale. AC, Watermaker, Electronics and Refrigeration are in good working condition. 4 solar panels keep the house batteries charged. A must see to appreciate. Motivated seller.

Replacing an icon is never easy, but when the Lagoon 450 replaced the 440, a new benchmark was created. The Lagoon 450 has taken several items ideas from its predecessor, enhanced them through owner feedback, and created a larger sail area for favorable cruising speeds.

The 450 flybridge version gives optimal visibility and access to sailing controls while providing easy access to the main cockpit and seating areas via twin stair wells. Cushions and lounging areas abound for the family and crew to relax under way or in port. The Sport version of the 450 allows boaters who wish to enjoy the comfort of a catamaran of 45 feet in a more conventional version, with a helm post on bulkhead in place of the flybridge.

As with all Lagoon catamarans the vertical windows provide superb visibility while maximizing interior space and keeping the interior cool under those overhanging eyebrows. Decks are easy to move around on with flush deck hatches. Lagoon’s proprietary gull wing bridge-deck design minimizes slamming in big seas.
