Like carrier, off course (6)

I believe the answer is:

astray

This clue is a double definition.

'like carrier' is the first definition.
(I've seen this before)

'off course' is the second definition.
(I've seen this before)

(Other definitions for astray that I've seen before include "In a lost state" , "Wandering lost" , "Off the right track" , "in the wrong place" , "on the wrong road" .)

I've seen this clue in The Telegraph.
