We’ve found advantages in having courses programmed into the club’s GPS:

• a course can be set quickly, by zooming to each waypoint and placing a buoy
• the courses can be adjusted, with sailors providing feedback to fine-tune buoy placement, and the waypoints updated.
• our standard size of 800m triangle + 1km long reaches for multihulls only just fits on the lake, and the GPS courses optimise their placement

Following are images of each course:

North-east starboard course	North-east course
Easterly course	Course for easterly winds, starboard rounding
East-south-east course	Course for south-easterly winds
Course for south-south-east winds	Course for southerly winds
Southerly course, starboard rounding	Course for south-west winds
Course for west-south-west winds	Course for west-south-west winds, starboard rounding.
Course for north-west winds. Fingers crossed we never use this one – NW winds always swing around; sometimes a full 180 degrees during a race	Course for Northerly winds. Which never happen, but hey, we’re prepared
