8-4-065
A floating mark secured to a sinker, either directly through a joint or by a cable that is held in tension by the buoyancy of the mark. The buoyancy chamber is normally below the surface of the sea.
Note 1:
The terms resilient beacon and elastic beacon have been used with this meaning, but their continued use is not recommended.
Note 2:
When the connection to the sinker is by a universal joint and the aid carries a light, the term articulated light is sometimes used. This usage is deprecated.
Please note that this is the term as it stands in the original IALA Dictionary edition (1970-1989)
