I believe the answer is:

hey

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

'cry for attention' is the definition.
(I've seen this in another clue)

'the yachtsman's' is the wordplay.
'HEY' is hidden within the letters.
However, I'm uncertain how this is indicated.

Can you help me to learn more?

(Other definitions for hey that I've seen before include "Exclamation calling attention" , "Exclamation to call attention" , "Call attracting attention" .)

I've seen this clue in the Evening Standard.
