Flier in marina distributed (6)
I believe the answer is:
airman
'flier' is the definition.
(synonyms)
'marina distributed' is the wordplay.
'distributed' indicates anagramming the letters.
'marina' with letters rearranged gives 'AIRMAN'.
'in' is the link.
(Other definitions for airman that I've seen before include "Flier" , "Aviator" , "crew member" , "Male flyer" , "Pilot" .)
