“The sail force” is the first chapter of the on-line book ‘SAIL HANDLING AND TRIMMING’, with theoretical foundations that will help us to understand in a clear and simple way how the aerodynamic forces are generated in a sail, in order to obtain the maximum performance.

In this second chapter of the on-line book “SAIL HANDLING AND TRIMING”, we will see the application of the theoretical principles to the correct way of trimming a sail, and also the importance of sail draft for a correct trimming.

In order to sail effectively and get the most out of the sails in every wind situation, our sailboat must be well balanced. In this third chapter of the on-line book ‘SAIL HANDLING AND TRIMING’ we will see how to achieve this balance of forces.
