How many miles wide Henry Hudson thought the Northe America was?

Henry Hudson believed that North America was much narrower than it actually is, estimating it to be around 100 miles wide at certain points. His explorations in the early 17th century led him to think that a passage to Asia was possible through this perceived narrowness. However, his assumptions were based on incomplete geographical knowledge of the continent at the time. Ultimately, Hudson's explorations contributed to a better understanding of North America's geography.
