Ships brand outside of regions (6)
I believe the answer is:
liners
'ships' is the definition.
(liner is a kind of ship)
'brand outside of regions' is the wordplay.
'brand' becomes 'line' (as in a line of products).
'outside of' suggests removing the centre.
'regions' with its centre taken out is 'rs'.
'line'+'rs'='LINERS'
(Other definitions for liners that I've seen before include "cruise ships" , "Large commercial ships" , "craft?" , "Large ocean-going ships" , "These go inside" .)
