A Running Fix is a basic but important navigation method used by maritime professionals to determine a ship's position when they can only see one landmark or navigation point. Think of it like taking two snapshots of where your ship is in relation to a lighthouse or other fixed point, but at different times. Ship officers use this technique when modern electronic tools aren't available or to double-check their electronic readings. It's a fundamental skill that shows a navigator's ability to use traditional navigation methods, which many employers still value even in today's technology-driven maritime industry.
