Crew members from Yarmouth and Sheringham (5)
I believe the answer is:
hands
'crew members' is the definition.
(I've seen this in another clue)
'from yarmouth and sheringham' is the wordplay.
'from' indicates a hidden word.
'HANDS' can be found hidden inside '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" .)
