Drown topless men coming to bay (6)
I believe the answer is:
engulf
'drown' is the definition.
(thesaurus)
'topless men coming to bay' is the wordplay.
'topless' means to remove the first letter.
'coming to' means one lot of letters go next to another.
'bay' becomes 'gulf' (I've seen this before).
'men' with its initial letter taken away is 'en'.
'en'+'gulf'='ENGULF'
(Other definitions for engulf that I've seen before include "Completely overwhelm" , "Bury" , "Swallow up like wave" , "Completely swamp" , "Lowered in rank" .)
