Vessel: one carrying sherry? (8)
I believe the answer is:
schooner
'vessel' is the definition.
(I know that schooner is a type of sailing vessel)
'one carrying sherry?' is the wordplay.
I cannot really see how this works, but
'one' could be 'er' (I've seen this in other clues) and 'er' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for schooner that I've seen before include "wooden vessel" , "In the main it is" , "Type of glass" , "Sailing vessel - drinking vessel" , "A measure or glass for sherry" .)
