Floundering - nor is he near the coast! (7)
I believe the answer is:
inshore
'near the coast' is the definition.
(I've seen this before)
'floundering nor is he' is the wordplay.
'floundering' indicates anagramming the letters (I've seen this in other clues).
'nor'+'is'+'he'='norishe'
'norishe' anagrammed gives 'INSHORE'.
(Other definitions for inshore that I've seen before include "not far from the coast" , "little out to sea" , "place near coast" , "Close to the land" , "towards the coast from the sea" .)
