Is it a draw at the marine exhibition? (7)
I believe the answer is:
tugboat
'is it a' is the definition.
I can't judge whether this defines the answer.
'draw at the marine exhibition?' is the wordplay.
'draw' becomes 'tug' (tugging is a kind of drawing).
'at' means one lot of letters go next to another.
'the marine exhibition?' becomes 'boat' (I can't justify this - if you can you should believe this answer much more).
'tug'+'boat'='TUGBOAT'
Can you help me to learn more?
(Other definitions for tugboat that I've seen before include "Powerful vessel used to pull larger ones" , "Ship pulling a larger one" , "Vessel towing larger vessels" , "Drawing craft" , "Vessel drawing" .)
