Announce deliveries at docking sites (6)
I believe the answer is:
berths
'docking sites' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for berths that I've seen before include "Docks" , "Beds on ships or trains" , "Beds in cabins" , "where sailors sleep" , "Beds on board" .)
