The series is composed of four races to be held on the second Thursday in November, December, February and March.  In the event racing is cancelled, the race will be held over until the following Thursday. (If this too is cancelled this race will be dropped from the series.) Racing commences at 5.30pm and will be held over various courses depending on prevailing weather conditions. Sailing will be inside and outside the harbour, and is a non spinnaker event.  This is a separate series from the Geoff King Motors Summer twilight series. The  handicaps used will be the handicap of that boat from the previous event. Results will be calculated independently of the Summer series.

Lady skippers must be full sailing members of CHYC. Registration fees for the series are included in the summer twilight series race fees  (July 2022- June 2023.) If a boat wishes to register for the ladies series only the skipper must contact the Offshore Captain.
