* Or other metal mooring approved by the Harbor Committee.

* Heavy chain length is one and one half times the water depth. Light chain length is equal to the water depth. Pennant length is two and one half times the height of the bow chocks plus the distance to the cleat or mooring bit.

* Double pennants or bridles are recommended.

A swivel is required between heavy chain and light chain. No other swivels are to be used.

All shackles and swivels must be safety wired and be one size bigger than the chain to which they attach.

Chafing gear is required on all pennants.

Moorings must be inspected annually. Every third year each mooring must be pulled and inspected out of the water.

The number of the mooring must be stenciled or somehow affixed to the mooring ball so it is clearly visible above the water.

No standards or inspection requirements can insure vessel security under all possible conditions. The Watch Hill Yacht Club and its Officers and Directors assume no responsibility for personal injury or property damage that results from use of mooring tackle that meets or exceeds the recommended standards set forth above.
