Vessel with lid full of bitter, nasty smell (9)
I believe the answer is:
whaleboat
'vessel' is the definition.
(I know that whaleboat is a type of boat)
'with lid full of bitter nasty smell' is the wordplay.
'with' becomes 'w' (abbreviation).
'lid' becomes 'hat' (synonyms).
'full of' means one lot of letters goes inside another.
'bitter' becomes 'ale' (type of beer or bitter).
'nasty smell' becomes 'B.O.' (body odour).
'ale'+'bo'='alebo'
'hat' enclosing 'alebo' is 'haleboat'.
'w'+'haleboat'='WHALEBOAT'
(Other definitions for whaleboat that I've seen before include "sailing vessel" , "Harpooner's vessel" .)
