All participants of WRA are required to act as coxswains from time to time.
In general, members are expected to cox one time for each three to four times that s/he rows.
What to do if you ARE the coxswain?
Check with the coach as to which boat you will be using.
Get a flotation device, whistle, cox box, lights (if it is fall or winter).
Check that lights work. Red and green lights are for the bow, and the white light is for the stern. If they need new batteries, get them in.
Check in with stroke and notify them if you are not very experienced at coxing.
Listen to what the coach for the day tells you about the outing - you will then know what to do on the water.
