Get the boat in somehow (6)
I believe the answer is:
obtain
'get' is the definition.
(I know that get can be written as obtain)
'boat in somehow' is the wordplay.
'somehow' indicates anagramming the letters.
'boat'+'in'='boatin'
'boatin' is an anagram of 'OBTAIN'.
'the' acts as a link.
(Other definitions for obtain that I've seen before include "Get, procure" , "Get - secure" , "Get or lay hold of" , "Come into possession of" , "Acquire or procure" .)
