Break it down into catagories:
Boat speed: Am I consistantly keeping up with other boats in like conditions? Is the problem point or speed? How do
I correct for either problem?
Boat handling: Am I getting around marks as quick as anybody? Tacking and gybing with others without losing distance? Am I hitting the line at speed, on time, and with space to accelerate?
"Strategery": Do I know what the wind is doing? Is it occilating, is there a persistant shift, or unpredictable ? Do I know what side of the course to go to and am I planning my start accordingly?
Tactics: Do I know the rules? What will I do if I don't get
clean air after my start? Always have a plan B ready to go
at all roundings and starts. Am I aware of what is happening
as the race unfolds?
Equipment: Are my sails OK? Is my boat set up like the A fleeters?
