Traveling to Europe by boat can vary significantly depending on several factors including the starting point, destination, and the type of boat used. For example, a cruise ship traveling from South America to Europe might take around 6-8 days, while a faster option like a private yacht could take less than 3 days.
On average, if you are traveling from a major port in North America or Australia to Europe by sea, it can take anywhere from 4 to 10 days, not including any stopovers or delays.
