Polyform's CC Series buoys share the same legendary history as our A Series. Developed shortly after the A Series, the CC has proven to be a valuable commercial buoy for over 50 years. It is used regularly as a mooring buoy, but because of its strength and flexible center tube it is used in many other applications. Long-line fisherman, fish farmers, geophysical researchers towing sonic exploration equipment, and many others find the CC Series to be the best buoy for the job. People who use Polyform's CC buoys can count on reliable performance, even in the most extreme conditions.
