OK Bear, but keep in mind the currents change on a hourly basis. One hour the currents can be mild. When there is the outgoing tide, they can be extreme. On the same windy day the outgoing tide can be dangerous but the incoming tide altogether different.
This is where the knowledge of the guide is important.
If you tried the idea of flags, to be accurate, it might necessitate changing them numerous times throughout the day which in my mind makes the idea unworkable.
