Lagoon – 420

Florida, United States

DOUBLE DOWN is a nice example of the spacious Lagoon 420 with a 4 cabin layout.  It has always been privately owned with no known charter usage.  Her current owners have sailed it to Florida from the Caribbean starting in Grenada.   

The design of the Lagoon 420 focuses on comfort.  The light oak Alpi woodwork and the laminated wenge floor give a modern and relaxing feel. Access into the saloon from the cockpit through a sliding glass door on the same level. The longitudinal galley opens directly on the cockpit, it is the most convivial and practical area, fully equipped with numerous lockers. The layout of the two hulls in the 4 cabin version are symmetrical with a central double bed in each cabin, a washroom with separate shower, large hull windows, lockers, and overhead hatches.

Highlights include:

–        Upgraded 75hp Yanmar engines

–        4 x 320 watt solar panels

–        600Ah Lithium Battery Bank

–        2000 watt inverter

–        Echo water maker

–        New mainsail

–        Air Conditioning (in salon only)

Double Down is available for showings by appointment in St Augustine, FL.
