Course Types

The exact course will be set on a daily basis accoding to the conditions and will be announced during the competitors briefing each morning. Please be aware that the course may be changed at short notice and it is your responsibilty to check the notice board and flags.

At the start end of the course there will be a lead-in buoy 150m before the start line denoting the “one competitor at a time” area. The start line is defined by anchored buoys that will display the course open/close flags. To enter the course it is necessary to sail between the buoys. When using a beach course, the inner buoy may be sat on the beach depending upon tides.

The end of the course is defined as an arc from the point where the competitor crosses the start line (this is done accurately by software when calculating the results). An arc of buoys is positioned to indicate an approimate end line distance just in excess of 500m as a visual guide to competitors out on the course.

It’s in your interest to sail fast beyond these buoys to ensure the best possible run speed is obtained. Competitors should continue beyond these course markers, so they can safely tack and return to the start line without impeding other competitors.

This type of course has two advantages:

  • It can accommodate wind shifts of 20 degrees or so without needing to be re-laid;
  • Different types of craft can sail on their individual fastest wind angle.

Plotting of course and GPS run data

The image below is an example of the run data for a "Harbour Course" being processed in the GPS Results software ; it shows the course as a blue area, and a multitude of runs through the course and around the harbour. 


The image below shows, in greater detail, the 'hot' area of the course in which competitor's runs are deemed to be qualifying. The course begins at the narrow end with a ~20m wide gate and extends in a pie/segment shape for a distance of 500m. The red marker determines the centre line of the 20m rectangular track. Each competitor's tracks are shown as the individual lines, heading both up and down the course. Software processing ensures that only those runs heading up the course the right way are selected.
