What makes a Boat sail to Windward ?

The sails on your boat act as an airfoil similar to an airplane wing which creates the lift to move the boat through the water. This video explains the theory behind how the air flows over your sail at different speeds to create that lift. We explore the camber of your sails and how you should set them up for light, medium and heavy airs. Using a wind tunnel we simulate the air flow and pressure created by this which propels your boat forward. At the end of the video we take a look at some basic controls you can use to adjust the camber of you sail to ensure you have the prefect setup for the prevailing wind. Using forestay and sheet tension to move the camber in the Jib forward and aft. This 20 minute video lesson will teach you the basic to help you improve your setup while sailing.
