All North Asymmetric spinnaker panels are computer molded, both horizontally and vertically, resulting in an exceptionally fair shape, and are optimized with North's exclusive Flow and Membrane computer simulation programs, which analyze pressure and stresses on the sail at various wind speeds and angles.

Polyesters tend to last longer than nylon styles, but are less resistant to tearing.
