Extraordinary size, boundless experiences

Impressive dimensions, unmatched onboard comfort and a true sense of luxury — the flagship of the Wia fleet.

Open deck, endless space

The monumental scale and clean lines of the Wia 520 Open captivate from the first moment.

Every part of the deck is designed for social living: the expansive bow lounge and sunbed area, the central kitchen island and the generous aft living space all come together to create the perfect setting for unforgettable moments on the water.

Effortless comfort, thoughtfully integrated

The Wia 520 Open is designed around the idea that life on the water should feel natural, open and uncomplicated. Every exterior element has been carefully integrated to create a cleaner experience on board — visually and functionally. The electrically operated shading system adapts within seconds, offering protection from the midday sun or creating a more intimate atmosphere for long evenings on the water. Beneath the open layout, hidden storage compartments preserve the yacht's calm and uncluttered character while keeping essential equipment always within reach. A fully walkaround deck layout allows seamless movement throughout the yacht, connecting generous sunbeds, social seating areas and the exterior kitchen counter into one continuous outdoor living space.

A welcoming interior with yacht-level comfort

The interior can be configured in multiple layouts, offering comfortable sleeping arrangements for up to six guests. Premium materials, fully equipped galley options and thoughtfully designed cabins create an environment that feels both luxurious and homely, making the 520 Open perfect for extended journeys.

Sustainable performance

The advanced electric propulsion system of the Wia 520 Open delivers silent cruising with zero local emissions, capable of up to 16 hours on the water in max-range mode — proving that exceptional size and sustainability can finally go hand in hand.

Built for the way you live on the water

The 520 Open was designed around a particular kind of owner: one who entertains often, cruises for the experience rather than the destination, and wants a flagship that feels as at home hosting a coastal lunch as it does anchored for a sunset with friends. It suits high-end leisure owners, luxury hospitality and charter operators, and coastal lifestyle buyers who want a strong, unmistakably flagship presence in the marina. At its best in coastal waters, premium marinas, Mediterranean cruising grounds and large inland lakes, the 520 Open turns every outing — a VIP hospitality afternoon, a premium charter, a long lunch on the water — into an elegant, silent experience built entirely around comfort and modern luxury.
