Benoit Lecomte (born 1967) is a French-American long-distance swimmer who swam several sections of the Atlantic Ocean in 1998. Many major media outlets initially wrongly reported that he swam the entire distance across the ocean, but the claim was dismissed and is not officially recognized by Guinness World Records since there is uncertainty about the distance that Lecomte actually covered swimming due to the fact he rested and slept on a boat as it drifted and made progress towards their final destination.
