Woman to sail away (4)
I believe the answer is:
lisa
'woman' is the definition.
'sail away' is the wordplay.
'away' is an anagram indicator (letters move away from their original places).
'sail' anagrammed gives 'LISA'.
'to' is the link.
(Other definitions for lisa that I've seen before include "Mona ..., also called La Gioconda" , "Mona . . . ., famous painting by Leonardo da Vinci" , "Leonardo da Vinci painted the 'Mona ....'" , "Girl" , "Most intelligent of Marge Simpson's children" .)
