Get home after boat is damaged (6)
I believe the answer is:
obtain
'get' is the definition.
('obtain' can be a synonym of 'get')
'home after boat is damaged' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'after' means one lot of letters go next to another.
'is damaged' indicates an anagram.
'boat' is an anagram of 'obta'.
'in' after 'obta' is 'OBTAIN'.
(Other definitions for obtain that I've seen before include "'Get, acquire (6)'" , "Come into possession of" , "Get, procure" , "Gain possession of" , "Get - secure" .)
