So, I got that information from a different Lemmy comment, and on the spur of your contradiction I went looking myself. My search results are flooded with mostly useless news articles (they went to tell stories, not relay technical information). Regardless, the most ambitious claim I've seen is to reduce emissions by up to 90% for a ship design that can't handle shipping containers and is about 1/4 the size of the largest ships being produced today.
Don't get me wrong, I want this to happen. In fact, I would ban carbon-fuel shipping today, if I could make it happen. That being said, I don't think we'll ever get back to 100% wind power.
The sail kite project has had claims of up to 10% fuel savings for about 20 years, now.
It's all moot when we should just be focusing on figuring out practical nuclear shipping. It's the only way to meet or exceed our current standard and be carbon-free. The NS Savannah proved it could be profitable ages ago, and that without any economy of scale to reduce costs.
