• Sur-Moor hard skin mooring buoys are seamless and tough, one-piece polyethylene shell
• Hard skin shells feature ultraviolet light absorbers for long-term life under the sun
• Filled with 2 lb density closed-cell foam to positively displace water
• Hot-dipped galvanized steel eyebolt and swivel
Note — Due to the fact that the (replaceable) metal rod through these buoys can be subject to hidden corrosion, prudence dictates that the top ring should only be used to lift the buoy out of the water to access your mooring pennants. The actual connection for your mooring pennants should be directly to the chain (or a moused shackle) attached to the bottom ring of the buoy - not to the ring, itself. See accompanying diagram. Fisheries recommends regular inspection of the rod, and replacement when necessary.
Heavy on the technical side...
The sole purpose of the mooring buoy is to support the mooring chain at the surface of the water. Choose a buoy witha buoyancy of at least twice the weight of the chain it must support so the buoy rides high enough in the water to make it easy to locate in adverse conditions (darkness, heavy seas, etc.).
The two preferred designs for mooring buoys are a traditional buoy with metal rod hardware, or a buoy with a tube through the center.
Both offer reliable flotation and will last for several seasons, depending upon the salinity of the water. Freshwater applications will extend the useful life of any mooring system.
A permanent mooring system, when properly designed, should securely position a boat so that it can be left unattended for long periods of time.
Each system usually consists of a mooring buoy (to float the chain), a mooring anchor and a length of chain (running between the anchor and the mooring buoy).
Also the proper ground tackle includes correct sized galvanized shackles and swivels. Always keep in mind, that the mooring system is only as reliable as the ?current? conditions of the environment.
