A vintage sort of sail? (8)
I believe the answer is:
navigate
'sail?' is the definition.
('navigate' can be a synonym of 'sail')
'a vintage sort' is the wordplay.
'sort' is an anagram indicator.
'a'+'vintage'='avintage'
'avintage' with letters rearranged gives 'NAVIGATE'.
'of' is the link.
(Other definitions for navigate that I've seen before include "Guide (a vessel)" , "Move around a website" , "Guide ship or aircraft" , "Move around while browsing the Internet" , "'Direct the course, of a ship say (8)'" .)
