Complete Charlie disembarks single-master (5)

I believe the answer is:
utter
'complete' is the definition.
(both can mean total)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for utter that I've seen before include "Say the words" , "Absolutely" , "Express; complete" , "talk" , "Give voice" .)
