Is it always best to use great circle sailing?

Great Circle Sailing is used for long ocean passages. For this purpose, the earth is considered a perfect spherical shape; therefore, the shortest distance between two points on its surface is the arc of the great circle containing two points.

Why are great circle routes used?

The most famous use of great circles in geography is for navigation because they represent the shortest distance between two points on a sphere. Due to the earth’s rotation, sailors and pilots using great circle routes must constantly adjust their route as the heading changes over long distances.

What is a great circle route and why is it important?
