Rwidman,
I learned something here. I did some investigating. It turns out what you say is correct. The No-Wake zone extends only a couple of hundred feet away towards the middle of the waterway.
What I also have learned during my investigation is

No Wake Zones
United States Coast Guard Auxiliary Southport
As you travel the Intracoastal Waterway and other areas you will
often notice signs that indicate no wake zones. These signs have
been put up because the passing boat wakes have caused damage or
erosion. The people that put these signs up are trying to keep
damage to a minimum. There are official no wake zones and there
are requests for no wake areas are from marinas and property
owners that are aware of the potential damage caused by these
wakes.
The average boater considers slowing down will reduce his wake
when in reality it generally causes more wake. Slowing down
drops the stern deeper in the water as the boat comes off plane
and the wake increases as the hull displaces more water.
To enter a no wake zone you must put the boats engine into dead
slow. That allows the boat to come off plane completely and
settle in its normal displacement mode. At that point you should
put the boat into clutch speed and observe your wake as you pass
the marked area.
PLEASE OBSERVE THESE NO WAKE ZONES AND REALIZE YOU ARE
RESPONSIBLE FOR YOUR WAKE AND THE DAMAGE THAT IT MAY CAUSE. BE A
RESPONSIBLE BOATER.
Boat Smart...Boat Safe...Wear It!
