The launch of the superyacht took place just a few weeks behind schedule, despite disruption caused by the coronavirus pandemic, the builder said.
"The last two years have been difficult, but we took a lot of health and safety measures, and, to offset delays experienced by our European suppliers, we worked around the problem and found ways to recreate lost time," said Alia president, Gökhan Çelik.
The yacht is now undergoing outfitting after which it will complete sea trials before being handed over to its owner. The world debut of the yacht has been scheduled for late September 2021, which coincides with the Monaco Yacht Show.
Çelik declared Al Waab II "the longest steel and aluminium yacht below 500GT in the world".
"Yachts are getting longer and wider, but owners still want to stay below the 500GT mark. We’ve seen increasing interest in this kind of yacht and so to be one of the first with such an impressive project is an important milestone for Alia."
Built from steel and aluminium, the sub-500GT superyacht is designed inside and out by Vripack, which also developed the naval architecture and engineering.
The owner's brief called for a "modern and fresh design" providing "comfort, space, luxury, privacy and stability at sea," the builder said. The simplicity of the layout and amount of outdoor space was specifically stipulated by the owner.
Key features include a sub-500GT interior, focus on exterior spaces and semi-transparent sides, creating a wind-protected area.
Accommodation on board is for a total of 12 guests in six suites, including a two-tier master suite. The cabin of the master sits on the upper deck, providing wide-reaching ocean views, while the dressing room and bathroom sit on the main deck below.
Glass played a leading role in the design of Al Waab II, with the yacht featuring glass bulwarks and floor-to-ceiling windows.
