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