KOCC, and HVVCC, both race on the same route, week after week, year after year. The only difference between the two is HVVCC's clubhouse is a short distance to the south of the KOCC clubhouse.
HDCC also use the same course on Firday nights during summer - HDCC's clubhouse is in Cormorant Rd.
Hope this link works - a map. There is a turnaorund at the end of Cormorant Rd, and the course runs generally coutner-clockwise:
