Mark number 1 is positioned at the end of the jetty, numbering continues around the water in a clockwise direction with the final mark being number 9. Mark 4 is nearest the bridge, Mark 7 at the far end. We also have 3 moveable marks that can be positioned as required. Races are normally run from the Officer of the Day (OoD) Cabin situated on the same bank as the club house with a transit arm, used as a start line extending out from a white pole from the OoD cabin. Sailing is not permitted beyond the X mark or beyond the bridge. The spillway boom area should be kept clear.
