Extraordinary range, boundless comfort

Uncompromising range, all-weather elegance and true flagship presence — the longest-legged Wia ever built.

Enclosed elegance, open by choice

The Wia 520 HardTop carries the same commanding scale as the rest of the flagship line, wrapped in an architecture built for every season. Large glass walls slide open across both sides and the stern, dissolving the boundary between the saloon and the open water in seconds.

Close them, and the same space becomes a fully sheltered, all-weather living room on the water. The 520 HT doesn't ask you to choose between indoor comfort and open-air freedom — it gives you both, on command.

Living space that widens with the horizon

At anchor, the Wia 520 HT reveals one of its signature features: motorised side panels fold down along both sides of the hull, expanding the deck into a wide lounging platform at the waterline. Paired with a hydraulic swim platform that lowers level with the sea, the transition from yacht to private beach club takes moments, not effort. A fully equipped galley with premium Corian worktops and twin fridge-equipped bar cabinets keeps entertaining effortless, while a walkaround deck layout lets guests move freely from bow to stern in one continuous, uncluttered space.

A true home on the water

The 520 HardTop is configurable across two or three cabins, comfortably sleeping up to six guests between the owner's and guest suites, each with its own en-suite bathroom. A third cabin with a French berth can be added for larger groups or longer journeys, and a walkaround bow layout is available for owners who favour deck space over cabin volume. Premium materials, considered detailing and generous headroom throughout create an interior that feels as elegant as it does genuinely livable — built for owners who want to disappear onto the water for days at a time, not hours.

Sustainable performance, without compromise

The Wia 520 HardTop is powered by a 100% electric propulsion system, delivering silent, effortless cruising with zero local emissions. In its long-range configuration, the 520 HT is capable of up to 26 hours on the water in max-range mode, or a comfortable 8-hour cruising day covering nearly 100 km — proof that flagship scale and genuine long-range capability can finally share the same hull without a drop of fuel.
