Fabricating yacht's ropework (7)
I believe the answer is:
rigging
'ropework' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for rigging that I've seen before include "Ropes, etc, on a sailing ship" , "part of craft?" , "Ship's ropes etc." , "Fraudulently fixing" , "Formation of masts etc. on a vessel" .)
