The Log History:
This post, ‘The Log History’, has connection with the history of maritime navigation, and not with the modern navigation. But, are interesting.
Some logs are not really logs, but rather processes for determining the speed of the ship.
As is the Dutchman’s Log.
Or other logs are no longer used, in the present, on board of the ships.
Like the Hand Log, which is the easiest and oldest log, and belonging of the sailing ships.
But, from the Hand Log remained the name of “Knots” for the speed unit of vessels.
The log line is marked by nodes at intervals of 14.62 m and, hence, from here comes the term of “Knots” for the ship’s speed.
