It’s also not the largest. During the age of sail one of the largest shipping boat was almost 8 times larger than this one. They are just playing the technicality of being wind powered and not a sail ship to con startup investors out of their money. But there have been even larger sail cruise ships. It’s just the game tech bros play, reinventing the wheel but coming up with a catchy marketing name that looks like disrupting the status quo to bait capital injection.
Still by that standard, there are larger sail ships today. Just not cargo ships, but cruise ships. It’s still a manipulative statement.
