The S0-1 (Lt Blue) all-purpose spinnaker for the International 420 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. For colours other than solid White or solid Lt Blue please contact your local North Sails loft or Agent
