Sailor to achieve his goal (6)

I believe the answer is:

target

I'm a little stuck... Click here to teach me more about this clue!

'his goal' is the definition.
'target' can be an answer for 'goal' (target is a kind of goal). I'm unsure of the 'his' bit.

'sailor to achieve' is the wordplay.
'sailor' becomes 'tar' (tar can mean a sailor).
'to achieve' becomes 'get' (I've seen this in another clue).
'tar'+'get'='TARGET'

Can you help me to learn more?

(Other definitions for target that I've seen before include "What's aimed at" , "Aim of an attack" , "Goal, objective" , "Object of attack" , "aunt Sally" .)

I've seen this clue in The Mirror.
