Crew members from Yarmouth and Sheringham (5)
I believe the answer is:
hands
'crew members' is the definition.
(I've seen this before)
'from yarmouth and sheringham' is the wordplay.
'from' says the answer is hidden in the clue.
'HANDS' is hidden in the letters of 'yarmouth and sheringham'.
(Other definitions for hands that I've seen before include "Passes" , "Measurements for horses" , "Cards given out in deal" , "Body parts; crewmen" , "Units for measuring horse's height" .)
