A rhumb is a line on the surface of a sphere that cuts all meridians at the same angle. At an angle bigger then 0° but smaller then 90° the rumb line never closes. In the form of a spiral it winds endless times around the earth and draws nearer the poles, without reaching them. It is the path taken by a ship or plane that maintains a constant compass direction.
