Steers vessels round one corner (6)

I believe the answer is:

pilots

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

'steers' is the definition.
(piloting is a kind of steering)

I don't understand how the remainder of the clue works.

(Other definitions for pilots that I've seen before include "Fliers or guides" , "They are licensed to fly aircraft" , "People who guide ships going into or out of a harbour" , "Airmen" , "They steer ships in and out of harbours" .)

I've seen this clue in the Evening Standard.
