Shambles getting yours truly on ship (4)
I believe the answer is:
mess
'shambles' is the definition.
(I've seen this before)
'yours truly on ship' is the wordplay.
'yours truly' becomes 'me'.
'on' says to put letters next to each other.
'ship' becomes 'ss'.
'me'+'ss'='MESS'
'getting' is the link.
(Other definitions for mess that I've seen before include "Service dining-area" , "Disarray" , "State of disorder" , "Clutter" , "4 [DISORDER]" .)
