Save individual on ship — a noblewoman (8)
I believe the answer is:
baroness
'a noblewoman' is the definition.
(baroness is a kind of noblewoman)
'save individual on ship' is the wordplay.
'save' becomes 'bar' (I've seen this before).
'individual' becomes 'one'.
'on' means one lot of letters go next to another.
'ship' becomes 'ss'.
'bar'+'one'+'ss'='BARONESS'
(Other definitions for baroness that I've seen before include "Lady peer" , "Peer's title" , "Lady Thatcher?" , "Female life peer" , "Noblewoman" .)
