Boat (and other things) found in the outskirts of Kilrush (5)
I believe the answer is:
ketch
'boat' is the definition.
(ketch is a type of sailing boat)
'other things found in the outskirts of kilrush' is the wordplay.
'other things' becomes 'etc' (I've seen this in other clues).
'found in' indicates putting letters inside.
'the outskirts of' suggests removing the centre (letters on the edges or outskirts are used).
'kilrush' with its centre removed is 'kh'.
'etc' inserted into 'kh' is 'KETCH'.
'and' is the link.
(Other definitions for ketch that I've seen before include "Two-masted sailing boat" , "Two-masted sailing ship" , "Jack" , "Small sailing vessel with two masts" , "Small two-master sailing vessel" .)
