This 2018 Lagoon 400 S2 is a fiberglass catamaran built for extended cruising, measuring 39 feet with a 24-foot beam. The yacht features two Yanmar 90-horsepower diesel engines with sail drives and folding propellers. The design prioritizes comfort and self-sufficiency, equipped with substantial solar generation (1,400 watts across seven panels), a 9-kilowatt generator, and 900 amp-hours of lithium battery storage. Systems include a watermaker, full air conditioning and heating, and a comprehensive suite of electronics including B&G navigation, radar, and autopilot.
The layout accommodates eight people across three cabins and two heads. The owner's suite spans an entire hull with a spacious berth, private ensuite head with separate shower, and abundant storage including a hanging locker and desk. Two additional cabins in the bows provide berths and hull ports. The main salon and galley occupy the center, with a dining table seating six. The galley includes dual refrigeration, a freezer, microwave, espresso machine, and three-burner stove.
Recent upgrades reflect extensive investment in comfort and capability. Updated electronics include a 12-inch Zeus plotter, Triton displays, and wind instrumentation added in 2026. Rigging improvements include new running lines and winch controls, plus an upgraded trampoline. Interior enhancements span air purification systems, a mini washing machine, modern entertainment including a 32-inch display, and security cameras. A 9-kilowatt Onan genset provides additional power backup.
The sail plan is comprehensive with a full-battened mainsail, asymmetrical spinnaker, code zero with continuous furler, and furling genoa. Deck equipment includes three Harken electric winches, a new windlass, dual anchors with substantial chain and rode, and a Highfield inflatable tender with 20-horsepower Honda outboard. Extensive safety gear includes an eight-person liferaft and emergency systems throughout.
