Rod George ends in some boat? (5)
I believe the answer is:
barge
'boat?' is the definition.
(I know that barge is a type of boat)
'rod george ends in some' is the wordplay.
'rod' becomes 'bar' (I've seen this before).
'george' becomes 'g'.
'ends in' says to take the final letters.
The final letter of 'some' is 'e'.
'bar'+'g'+'e'='BARGE'
(Other definitions for barge that I've seen before include "Freight-carrying boat" , "Possibly lighter" , "Canal boat maybe" , "Canal-boat" , "Flat-bottomed canal boat" .)
