Transport worker in company leading a vessel with King on board (8)
I believe the answer is:
coachman
'company leading a vessel with king on board' is the definition.
I can't judge whether this definition defines the answer.
'transport worker' is the wordplay.
'transport' becomes 'coach' (coach is a kind of transport).
'worker' becomes 'man' (man is a kind of worker).
'coach'+'man'='COACHMAN'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for coachman that I've seen before include "used to appear on the box" , "Horse-drawn carriage driver" , "Wagoner" .)
