Unanchored (6)
I believe the answer is:
adrift
'unanchored' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for adrift that I've seen before include "'Floating without direction, not tied up (6)'" , "No longer fixed in position" , "Floating uncontrolled" , "Unanchored - lost" , "(Of boat) moving out of control" .)
