Spinnaker operate within an airflow that generates lift. A well designed spinnaker will have taut leading edges when filled; leading edges that curl in will both reduce the lift and risk of collapse of the spinnaker. A well designed spinnaker will also have a smooth curve when filled, with no bubbles or depressions caused by inconsistent stretching of the sail fabric. Any deviations from a smooth curve will cause the airflow over the leeward side of the sail to separate causing a reduction in lift and reduced performance. There are two main categories of spinnakers, symmetric and asymmetric depending on whether
