Financially solvent (6)
I believe the answer is:
afloat
'financially solvent' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for afloat that I've seen before include "Buoyant: solvent" , "Aboard ship" , "Borne on the water" , "On board at sea, on ship" , "On the surface" .)
