Channel's only occupant is a naval hero (6)
I believe the answer is:
nelson
'a naval hero' is the definition.
(I've seen this before)
'channel's only occupant' is the wordplay.
'NELSON' is hidden within the letters.
However, I am uncertain how the hidden word is indicated.
'is' is the link.
Can you help me to learn more?
(Other definitions for nelson that I've seen before include "Sailor" , "Naval hero, d. 21 October 1805" , "Admiral; wrestling hold" , "Lady Hamilton's navy lover" , "British admiral, d. 1805" .)
