There’s a buoy that is supposed to mark where channels join (not shown in the link), but they’re not in use in my area. The channels are a bit like a side road joining up with a curve in the main road, except being a channel the buoys aren’t exactly dense. So, in my case, i can travel in a straight line and the markers switch sides. I remember that one, but there’s another three that are similar in nature that I don’t get to frequently and have to think about. The added fun is that the are is a bunch of channels in a pile of rocks (islands) in a body of water; it’s not like I’m travelling up or down a river.
I have charts, but that would be cheating. also worth observing that the area is not dangerously busy.
Because the other response was less than helpful, and I was curious myself, I found this great page!
It explained a few types of markers and how to interpret them
