Youth leader has odd chat in boat (5)
I believe the answer is:
yacht
'boat' is the definition.
(I know that yacht is a more specific form of the action boat)
'youth leader has odd chat' is the wordplay.
'youth leader' becomes 'y' (I've seen this in other clues).
'has' means one lot of letters go next to another.
'odd' indicates an anagram.
'chat' with letters rearranged gives 'acht'.
'y'+'acht'='YACHT'
'in' is the link.
(Other definitions for yacht that I've seen before include "Sailing craft" , "Sailing boat" , "Type of boat" , "Sailing or motor vessel for cruising or racing" , "Fast sailing vessel" .)
