Mooring Buoys are an important part of a marine setup. Proper anchoring, chain, and flotation are paramount for this peace of mind! TDC uses only 2000 lb anchor blocks with heavy galvanized american-made chain. Our buoys are designed with a through chain setup that prevents premature chain wear. Where depths are greater than 20 ft, a secondary mid-line buoy must be installed to support the weight of the heavy chain as part of our installation. Optionally you may have your buoy permanently "weld mark" numbered to prevent theft and aid in mooring.
