The S-01 all-purpose spinnaker for the International 420 Class performs well on both runs and reaches. It has the largest projected area of all our 420 spinnakers, and the depth is balanced from top to bottom to make trimming easier. Since the sail itself is a little flatter than the S-05, you can play the spinnaker pole height to stabilize it when required. Custom color spinnakers are available. North Sails will contact you after your order is placed to discuss your preferred color scheme.
