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