The glossary in the 1966 edition of Bowditch defines a sea mile as a nautical mile. In the 2002 edition, the glossary says: An approximate mean value of the nautical mile equal to 6,080 feet; the length of a minute of arc along the meridian at latitude 48Â°.. The sea mile has also been defined as 6,000 feet or 1,000 fathoms, for example in Dresner's Units of Measurement.
