S5’s are an ocean racing sail that is also called a “Storm Spinnaker or Chicken Chute” because of their small size. The sail has no shoulders and has an all-purpose shape geared more to running than reaching since most boats would heel out of control with the wind on the beam in such high winds.  It is truly bulletproof, usually made out of 2.2 oz. nylon. On a fractionally rigged boat with masthead spinnakers, the A5 is designed to fly from the hounds (the sheave just above the forestay). This makes the sail shorter on the luff, foot length and width.
