What is the biggest galeon yacht?

Can you enlighten me on the largest galleon-style yacht in existence? I'm particularly intrigued by the dimensions, features, and the manufacturer behind this maritime marvel. It's fascinating to learn about the engineering prowess and design innovations that have culminated in the creation of such a colossal vessel, embodying the charm and elegance of the golden age of sail. Additionally, I'm curious to know if it has been customized to cater to specific luxury needs or if it adheres closely to traditional galleon specifications.
