The process required tossing a floating object like a piece of wood and calculations were made based on the time that elapsed to pass the ship. The sandglass, also known as an hourglass, was a critical instrument to measure the speed.
At first, the markings were simply knots in the line. After time, sailors worked knotted cords into the log-line. The terminology evolved into the nautical mile. The sandglass became a key instrument on ships of the day. Micro-Mark offers a replica of the sandglass instrument used to count knots on ships for hundreds of years.
