Out of debt on the surface (6)
I believe the answer is:
afloat
This clue is a double definition.
'out of debt' is the first definition.
(I've seen this in another clue)
'on the surface' is the second definition.
(I've seen this before)
(Other definitions for afloat that I've seen before include "On board a ship; out of difficulty" , "Buoyed" , "Buoyant: solvent" , "get out of debt" , "At sea, drifting aimlessly" .)
