Some good advice from rick and paddyT.
That term to me, is all about the current. The wind and tide will generally set your drift, depending on your location but the current is important for reef fishing! In my experience, I generally noticed bait stick harder to the structure and closer together with more current. The “no run, no fun” goes in hand with “find the bait, find the fish”.
Current will also determine what side of structure the bait sits on. This is also worth noting in your travels. Sometimes it will sit at the front and then others times the rear depending on the strength!
