Sy Design has introduced Harmonia, a 63-meter yacht concept with striking design features and expectations for strong long-distance cruising performance. The yacht’s most distinctive feature is its main deck, which is just one meter above the waterline.

Its fluid exterior, defined by a continuous arch from stern to bow, shelters a four-deck layout engineered for both comfort and endurance. Though the designers have not yet published firm data on propulsion, range or top speed, Harmonia is conceived in the tradition of superyachts built for long-haul cruising.

Inside, large windows and wide doors open up the main deck saloon, where warm neutrals and generous furnishings flow into verandas. The owner’s suite spans the upper aft deck with indoor-outdoor living aboard, joined by four VIP cabins and a master stateroom.

Outdoor areas are a central part of Harmonia’s appeal. A circular bow platform offers a social lounge, convertible sunbeds and a pool, while the fly deck is divided by a central bar. One side is conceived as a bar lounge, the other focused on a pool with sunbeds and even a waterfall cascading from the bar structure.

Though Sy Design has not yet disclosed propulsion specifics, the aesthetic and functional layout suggest a yacht optimized for cruising comfort, long-range voyaging, and guest experience over top speed.
