Log Speed is a traditional maritime term used in navigation to measure how fast a ship is moving through water. While modern ships use electronic speed measuring devices, understanding Log Speed remains important as it appears in navigation records and historical data. The term comes from the old practice of using a wooden log tied to a rope (log line) to measure ship's speed. Today, it's often mentioned in job descriptions when employers need crew members who can work with both traditional and modern navigation methods. This skill is similar to being able to read both digital and analog clocks - it's part of comprehensive maritime knowledge.
