Ship gets note to hang about (6)
I believe the answer is:
linger
'hang about' is the definition.
(I've seen this before)
'ship gets note' is the wordplay.
'ship' becomes 'liner' (liner is a kind of ship).
'gets' indicates putting letters inside (gets can mean captures or absorbs).
'note' becomes 'g' (musical note).
'liner' placed around 'g' is 'LINGER'.
'to' acts as a link.
(Other definitions for linger that I've seen before include "Delay departure" , "Hang about, don't be in a hurry to go" , "Be slow to go" , "Remain behind" , "Stay behind" .)
