Overview

Excerpt from The Clipper Ship Era: An Epitome of Famous American and British, Clipper Ships, Their Owners, Builders, Commanders, and Crews, 1843-1869 The word knot is now frequently used to express long distances at sea. This is an error, as the term knot should be used only to denote an hourly rate of speed; for instance, to say that a vessel is making nine knots means that she is going through the water at the rate of nine knots an hour, but it would be incorrect to say that she made thirty six knots in four hours; here the term miles should be used, meaning sea miles or knots. The term knot is simply a unit of speed, and is derived from the knots marked on the old-fashioned log line and graduated to a twenty-eight-second log glass which was usually kept in the binnacle. In this book the word mile means a sea mile and not a geographical or statute mile. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
