Captain's spot (4)
I believe the answer is:
helm
'captain's spot' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for helm that I've seen before include "Position of leadership" , "Steering device" , "Tiller, steering wheel" , "Steer (a boat/ship)" , "Steer (a boat or ship)" .)
