Get a damaged boat in (6)
I believe the answer is:
obtain
'get' is the definition.
('obtain' can be a synonym of 'get')
'a damaged boat in' is the wordplay.
'a damaged' is an anagram indicator.
'boat' anagrammed gives 'obta'.
'obta'+'in'='OBTAIN'
(Other definitions for obtain that I've seen before include "Come into possession of" , "Get one's hands on" , "Get - secure" , "'Get, acquire (6)'" , "Get or lay hold of" .)
