The All Purpose Full Radial Spinnaker is designed to be used at 80 - 140 degrees AWA and up to 15 knots AWS.
This sail is designed to be the work horse of any inventory and covers a large range. It has fuller girths and is designed to lift and fly away from the boat. The top 10% of the sail being flatter allows the spinnaker to set away from the rig before the body of the sail curves down. The result is a sail that flies out to windward, away from the disturbed air of the mainsail and rig, in clear air flow.
