Get boat out at home (6)
I believe the answer is:
obtain
'get' is the definition.
(I know that obtain is a kind of get)
'boat out at home' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'boat' anagrammed gives 'obta'.
'obta'+'in'='OBTAIN'
(Other definitions for obtain that I've seen before include "Get or lay hold of" , "Hold good" , "Get or receive" , "'Get, acquire (6)'" , "Acquire or procure" .)
