CCI are pleased to offer a conversion kit for the 505 to double spinnaker pole. This kit is intended for converting existing 505 single pole systems to a high performance proven double pole solution. With the allowance for carbon spinnaker poles, you add no weight and you can expect to shave at least 3 seconds off a traditional single pole gybe. No guarantee on this time, but it will definitely improve downwind speed during gibing, especially when the breeze is on.
