Wake dissipation with distance

I have been reading a lot of anchorage reviews recently. I find it
interesting when a reviewer writes something like: "you are far enough off
the channel for wakes to dissipate." My experience has been that wakes don't
dissipate much with distance. Rather, the further I am from a passing boat,
the more waves I get from that wake, without much reduction in amplitude. If
I go through a wake close to a passing boat, I see 2-3 waves. If I am
anchored 1,000' from a passing boat, I might see and feel 15 waves roll by.
Something similar happens on heavily traveled open water such as Long Island
Sound. On a glassy calm, no wind day, there will be noticeable wave trains
traveling in all directions, sometimes with no boats in sight. These waves
are clearly boat wakes. I'm wondering if others have noticed the same thing.
