modern sailing galleon?

so I was reading this: https://www.bbc.com/news/world-europe-51067440 and remembered that I'd thought up something similar; using cargo ships to cross the atlantic.

anyway, if my math is right, this https://drive.google.com/open?id=1kXMnEZYN84bMQfYmBJ9shh9xvhxP0GMu&usp=sharing trip, should take a month at 1800's sailing speeds.

Galleons, the big sailing ships, could carry 900 or more tons of cargo, which works out to about as many cars (450 or so) as a modern ferry. Leaving space for people and other items, you could easily fit as many people and cars on it as you could on the old ferry to PEI that the Confederation Bridge replaced. (220 cars and 600 people)

This is all assuming a boat built to the standards of 1800. It is 2020, and we have more advanced technology and materials. A modern sailing galleon might not even be made from wood, but some sort of fibreglass. It likely would not be a galleon but a clipper of some sort, or some other design. Even if it is made from wood, we have technologies to better streamline hull shape. Many people are already starting to seriously look at replacing current cargo vessels with some kind of sail powered vessels.

This plan would have three stops on either side of the atlantic. Boston, Halifax, and St. John's, followed by Cork, Plymouth, and Cherbourg. It would connect the United States and Canada with Ireland, the UK, and France; thus connecting to the EU.
