Course Made Good Meaning in Sailing

Course made good represents the actual path a boat traveled between two specific geographic points. This measurement accounts for the effects of wind, current, and waves on the movement of the vessel. It is often a straight line between the start and the finish regardless of the zigzagging path. Sailors compare this distance with their intended heading to measure the efficiency of their navigation. Modern GPS systems calculate this value automatically to help the crew stay on the correct track. One specific example involves a navigator measuring the course made good after a long ocean crossing. This tells the sailor the true direction and distance covered over the actual ground surface. Knowing this value helps the captain adjust the steering to compensate for a strong side current. It is a vital piece of information for estimating the arrival time at a distant port. Beginners use this concept to understand how external forces push a boat off its intended line. This data provides a clear picture of the actual progress made during a sailing trip.
