Please, how do you use the red and green true wind angle and heading indicators.

Red is a straight line indicating your course (or heading) while the green line is the True Wind Angle (TWA) indicator of where the router is forecasting you to be if you continue on that TWA.

If anyone can help me with the Blue Line's purpose,please? I have noticed that it is close to the red, but the angle increases the closer we get to the higher northern or southern latitudes

Blue is the orthodromic route

The blue line is the great circle line - the shortest distance between two points on a sphere. It's the line the boat follows between position waypoints. It's as straight a you can get on a circle, but heading is not constant.

The red line (constant heading) is also called a loxodromic and it's actually not straight.
