Sand Point Naval Air Station

On June 13, 1946; Bridle Buoys were laid on Lake Washington, the buoy pictured at right was most certainly used for that purpose.

In 1946, the question "Could Navy aircraft legally moor on Lake Washington?" A flurry of dispatches flew between Sand Point and The bureau of Aeronautics, establishing the Navy's rights.

On June 15th NAS Seattle was informed that 24 PBY's would arrive from Alameda, with six coming in each day.

Mooring buoys are distinguished by the addition of a fitting to receive a ships mooring chain or hawser. A mooring buoy typically consists of an anchor, a tether and a float marking the location of the anchoring system. Below photo was taken at Great Barrier Island, New Zealand. They are about 4 feet in diameter.

Commercial buoys are typically used for temporary moorage of a vessel that is awaiting transit, or loading or offloading. Often these vessels are barges. Recreational buoys are used as semi permanent moorage for recreational vessels. The size of these vessels are typically between 4 and 12 meters in length, with smaller vessels moored on private tidelands or on shore and larger vessels moored in marinas.                                             from GlobalSecurity.org

Bridle Information from:

Admiralty manual of seamanship  or All About Buoys

 A bridle is several feet of line, (rope or chain) allowing the buoy to float around the plane being moored.

Another use for buoys of this size are to SUPPORT SUBMARINE NETS IN HARBOR DEFENSE AREAS
