German on row with empty holy vessel (6)
I believe the answer is:
dinghy
'vessel' is the definition.
(dinghy is a kind of vessel)
'german on row with empty holy' is the wordplay.
'german' becomes 'g' (abbreviation).
'on' is a charade indicator (letters next to each other).
'row' becomes 'din' (both can mean a loud disturbance).
'with' says to put letters next to each other.
'empty' means to remove the middle letters.
'holy' with its centre removed is 'hy'.
'g' put after 'din' is 'ding'.
'ding'+'hy'='DINGHY'
(Other definitions for dinghy that I've seen before include "little boat" , "Small open boat, maybe a rubber inflatable" , "Small boat, may be a rubber inflatable" , "craft" , "Small boat propelled with oars" .)
