Answer
Rhumb lines, introduced by Mercator's 1569 map, revolutionized navigation. Unlike great circles, which represent the shortest distance between two points on a sphere, rhumb lines are straight lines that intersect all meridians at the same angle. This simplified course plotting, making it easier for sailors to determine their direction and distance traveled. Rhumb lines became the standard for nautical charts, enabling more precise and efficient seafaring.
