Turkish yard Alia Yachts has announced the delivery of its custom 50-metre superyacht Atlantide, previously known as ALY501 throughout construction. According to BOATPro, the new build departed its Antalya sheds in July and has spent the summer cruising the Turkish coastline and nearby Greek islands.
The yacht was launched in November 2025, with teaser imagery revealing her futuristic, single-deck profile, complete with an "aircraft-carrier" bow, penned by Vitruvius Yacht Design, with naval architecture by Mulder Design.
"We summarised the message of purity and speed in one line: the sheerline, the separation between the hull and the superstructure,” explained Philippe Briand, founder of Vitruvius Yacht Design. Atlantide is said to feature "the sleekest and lowest profile" ever designed by the studio.
The new build was developed as the first Fast 50 yacht from Alia, constructed in high-strength Alustar aluminium with a full carbon superstructure to combine "extreme lightness" with "remarkable rigidity and efficiency". Alongside a lightweight construction, she is engineered for high speeds, powered by three water-jet propulsion units delivering a top speed of 35 knots.
Most details of Atlantide remain private, though her interiors, drawn by Liaigre, are said to be developed around the owner’s vision of "balance, wellbeing and life on the water". Known features include extensive glazing, a large uninterrupted deck and broad aft terraces.
With an 11-metre beam and 498GT of internal volume, Atlantide is also said to offer "generous accommodation" for her owners and guests. Further details are anticipated in the coming months.
"Atlantide demanded a great deal of everyone involved," said Gökhan Çelik, president of Alia Yachts. “For Alia, the challenge was to make every part of an ambitious vision work together as a complete yacht. That took years of engineering, craftsmanship and determination. I am enormously proud of our team and of the yacht they have built."
According to BOATPro, Alia Yachts currently has four superyacht projects on order or under construction, the largest of which is its upcoming flagship.
