I think you may have your numbers reversed. 1 nautical mile is approximately 1.15 statute miles. A nautical mile equals 1 minute of rotation of the Earth at the equator. Knots are not a measurement of distance but of speed. A boat traveling at 10 knots will cover 240 nautical miles in 24 hours.

But getting back to tying knots, I believe Ashley's Book of Knots is still considered the Bible of knots.
