I think it was a waste of potentially good sharking berley myself.
I have great difficulty recalling any pleasurable experiences regarding PWC operators within cooee of me while i am fishing. The slow down rule must be printed in fine print on the last page of thier rulebook.
I occasionally use a PWC myself to reach waters that are not accessible to with normal boats hence I do not create a stir with anyone else on my sojourns.
