About this Lesson

In ancient times, the only way to measure ship speed was use a method called “heaving the log." This approximate method of ship speed measurement was used until 1500-1600s when the 'chip log' method was invented. (Both methods were probably invented by Dutch sailors.) The later method involved knots, and in fact is the origin of the nautical speed unit:  the knot.  This hands-on lesson explores this methodology.  Please note that this is an on-site lesson and advanced reservations are required.  Please contact 860.572.5322 prompt #1.
