Theory of Great Circle Sailing and Composite Great Circle Sailing (Solved Example)!!

In this video, I explain the theory behind Great Circle Sailing (and difference with Mercator Sailing). I also solve an example of Composite Great Circle Sailing numerical-based question.
The concept behind Gnomonic Charts and Mercator Charts is also discussed.
