Hemp fibre in refurbished sails (5)
I believe the answer is:
sisal
'hemp fibre' is the definition.
(I've seen this before)
'refurbished sails' is the wordplay.
'refurbished' indicates anagramming the letters.
'sails' is an anagram of 'SISAL'.
'in' acts as a link.
(Other definitions for sisal that I've seen before include "constituent of rope" , "Agave yielding fibre" , "Agave rope-fibre" , "Strong rope fibre" , "Plant producing rope" .)
