Boat from Portugal (3)
I believe the answer is:
tug
'boat' is the definition.
(tug is a kind of boat)
'from portugal' is the wordplay.
'from' indicates the answer is hidden within the clue.
'TUG' can be found hidden inside 'portugal'.
(Other definitions for tug that I've seen before include "Pull suddenly; boat" , "Small boat for towing others" , "Small boat designed to pull larger ships" , "Pull vigorously at or tow" , "Boat to pull larger one" .)
