Jack,
Don't feel bad. It would be a rare person that knew what they were unless you lived in a lobstering area. You might be interested to know that the paint patterns on the buoys are used to identify a particular fisherman's pot or string of pots. In some of the better lobstering areas you might find a dozen or more different buoys in close proximity.
Cheers,
Mr. B
Thanks for the info Mr. B. They are certainly colorful and, I thought, photogenic.
