A cycling champ in hail at sea (4)

Ross

I believe the answer is:

ahoy

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

'hail at sea' is the definition.
(I've seen this in another clue)

'a cycling champ' is the wordplay.
'cycling champ' becomes 'hoy' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'a'+'hoy'='AHOY'

'in' is the link.

Can you help me to learn more?

(Other definitions for ahoy that I've seen before include "Mariner's challenge" , "Nautical call for attention" , "Sailor's shout for attention" , "Hullo, sailor!" , "Nautical shout" .)

I've seen this clue in The Sun.
