My question was worded perfectly.

There is only one best answer.
The man who wrote a book about his voyage, in which he
sailed around the world non-stop returning to the port he left
over a period of 313?

Nothing else could compare.

Perhaps you should define 'most famous'. Many famous sailors have sailed
from falmouth, myself included.
