Take notice of the subject line of this thread. Buoys clutter the chart
and provide a dangerous collision hazard on the water. We have put up
with this hazard for years because in the past we needed buoys. With the
arrival of GPS, they should be removed.

Ted,

That's not a buoy, its a daymark.

LOL! Yes, Jack, That's true. Well, its almost true. The Coast Guard also
calls them dayboards.

If I were to give a legalistic response I would have pointed out to you that
I never claimed that the collision object in the photo was a buoy but the
real answer is that I'm using the word "buoy" to mean any and all objects
placed in the water in an attempt to assist in navigation. Whether the
object is a floating buoy or a wooden post driven into the mud or a tower
mounted on a concrete base (or even a simple piece of 3/4" PVC water pipe
stuck into the mud with a rid tip as is common around here) is irrelevant to
this discussion. I use the word buoy because there may be many people
reading this thread who are new to boating and might not know what a daymark
is. Just about everyone in the world knows what a buoy is.
