Ship’s gone all wobbly (7)
I believe the answer is:
galleon
'ship's' is the definition.
(I've seen this before)
'gone all wobbly' is the wordplay.
'wobbly' indicates an anagram.
'gone'+'all'='goneall'
'goneall' is an anagram of 'GALLEON'.
(Other definitions for galleon that I've seen before include "Ship of the line" , "Trader" , "Old Spanish ship" , "All gone (anag.)" , "Large old square-rigged sailing ship" .)
