I identify ship that's disorderly (2,1,4)
I believe the answer is:
in a mess
'disorderly' is the definition.
(I've seen this in another clue)
'i identify ship' is the wordplay.
'identify' becomes 'name' (synonyms).
'ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'i'+'name'+'ss'='IN A MESS'
'that's' is the link.
(Other definitions for in a mess that I've seen before include "Tucker here for Tommy" , "at sixes and sevens" .)
