Procure boat in storm (6)
I believe the answer is:
obtain
'procure' is the definition.
('obtain' can be a synonym of 'procure')
'boat in storm' is the wordplay.
'storm' indicates anagramming the letters.
'boat'+'in'='boatin'
'boatin' anagrammed gives 'OBTAIN'.
(Other definitions for obtain that I've seen before include "Acquire, secure" , "Get or receive" , "Acquire or procure" , "'Get, acquire (6)'" , "Get, procure" .)
