The CM Series Mooring Buoy has been designed to provide the ultimate in strength, durability and boat protection, giving increased security to any mooring. Polyform makes two versions of mooring iron, one from galvanized steel with a protective vinyl-coated eye, and the other from durable stainless steel, which is available on special order. To provide strength and security, each version features a 1/2″ central rod, a large eye (4-3/8″ diameter), and a swivel (1-1/2″ wide). The CM Series is a long tested standard in mooring buoy design and is preferred by many boaters worldwide. The CM is available in either red or white with a blue stripe.

To figure out what size buoy you will need, determine the weight of the chain it must support. All chain has a stated weight per foot. Add another 25% to the total weight for safety. Always use chafing gear where mooring lines run through bow chocks or are likely to contact deck hardware. A thimble on the shackled end will prevent chafe at the buoy.
In a hard blow, the holding power of the mooring can be increased by lengthening the mooring pennant. This increases the scope of the mooring providing greater holding power – just be sure to check other boats in the moorage first to ensure you won’t foul another moored boat. In adverse conditions, a second mooring pennant can be run to the top eye as a safety in case the primary pennant chafes through or fails. All shackles should be moused to prevent opening. Electricians plastic tie wraps are an excellent means of securing a shackle.
