==================================

I assume they are charted?

The builder probably didn't get much previous chance to fine tune his
navigation skills (or learn his limitations).

They might be charted, but most people don't use charts around there.
In a lot of places they will be every 100 yards more or less and they
are not marked and most are submerged. You can usually see them by the
ripples on the water as the current goes over them, and most of the
time you can motor over them, but sometimes you can't, so it's best to
go slow.
