Vessels from Holland draw fleet out (9)
I believe the answer is:
delftware
'vessels from holland' is the definition.
(type of Dutch ceramics)
'draw fleet out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'draw'+'fleet'='drawfleet'
'drawfleet' with letters rearranged gives 'DELFTWARE'.
(Other definitions for delftware that I've seen before include "crockery" , "Decorative stuff" , "pottery" .)
