The Mediterranean sea certainly does, I have swum in it many times.
The furthest a person has swum without assistance from a machine is approximately 110 miles. This record was set by Benoît Lecomte in 1998 when he swam across the Atlantic Ocean from Massachusetts to France.
As of my last knowledge update in October 2023, approximately 100 individuals have successfully swum across the Atlantic Ocean. This feat is incredibly challenging, requiring exceptional endurance and skill, with most swims taking place between the Canary Islands and the Caribbean. Notable swimmers include Benoît Lecomte and Martin Strel, who have made headlines for their extraordinary journeys. The exact number may vary as new attempts are made and completed.
