All gone to repair sailing ship (7)
I believe the answer is:
galleon
'sailing ship' is the definition.
(galleon is a kind of sailing ship)
'all gone to repair' is the wordplay.
'to repair' is an anagram indicator (letters are fixed or repaired).
'all'+'gone'='allgone'
'allgone' with letters rearranged gives 'GALLEON'.
(Other definitions for galleon that I've seen before include "Trader" , "Large old square-rigged sailing ship" , "Ship of the line" , "Old Spanish war-ship" , "Large Spanish sailing ship of yore" .)
