After six years of exploring the world, our kids have grown up and we are sadly saying goodbye to our cruising life. As we transition back to land life we are starting to share that Dafne is looking for new owners. We are available to deliver her and help with the transition.

This Lagoon 500 (hull #97) was originally customized by a liveaboard, long-distance cruising family and sailed from France to Australia over 6 years as their children grew. It was purchased by her current owners in Australia, another liveaboard, cruising family of five. They completed their own circumnavigation, sailing west to the U.S. over six years. Her owners maintained and upgraded all safety and comfort features to a high level (lithium and solar, new rig, hardtop bimini). Now that her current owners’ children have left home, she is ready to take her next passengers around the world. Dafne II is blue-water ready and outfitted for a safe and comfortable home life.

With an 11kw generator, 1200ah Enerdrive lithium battery system, and 2.1 kw solar she is designed to run large household-sized appliances including washing machine/dryer, induction cooktop, and Bosch upright 264 liter fridge/freezer. Set up for family blue water cruising, Dafne II features a 220 lph sea recovery aquamatic water maker, 6 air-con units, center-console tender with 30HP 4-stroke outboard, hardtop bimini with surrounds, cockpit surrounds, water toys, and all the tools and spares for any adventure. With a Hydranet Zoom mainsail (2019) and new genoa (2024), Dafne II performs very well under sail and is easily handled shorthanded from her high-visibility flybridge equipped with fully electric winches and new electronics.
