basic pivoting points 

knowing how your boat is reacting with wind is key to successfully work your way in the harbour.
The video is a starting point to understand, it is set up to help you understand how your boat is reacting with wind. ( please take note that you might have currents as well, so we're just talking about wind ! )
Once you understand the basics, you can check the video regarding the different maneuvers.
I hope this helps you enjoy boating more....
Best regards,
