It is normally manufactured from light 3 / 4 ounce to medium 1.5 ounce weight spinnaker cloth to help with lower apparent wind speeds. the optimum apparent wind speeds and sailing angles for this type of sail. Built from heavier spinnaker cloth than the A2, this heavy air running sail is targetted at the 10-25kts TWS range and will fly at very deep angles, 120-165° AWA.

An Asymmetric spinnaker (otherwise known as a gennaker or A-Sail) is cut more like a lightweight genoa and as such it has a permanent luff, tack and clew.
