Famous person to take lodgings right on the sea (9)
I believe the answer is:
starboard
'right on the sea' is the definition.
(nautical term for 'right')
'famous person to take lodgings' is the wordplay.
'famous person' becomes 'star' (I've seen this before).
'to take' means one lot of letters go next to another.
'lodgings' becomes 'board' (as in bed and board).
'star'+'board'='STARBOARD'
(Other definitions for starboard that I've seen before include "Right side of ship or plane" , "One side of a ship" , "Opposite of port" , "right to 14 [YACHTS]" , "Right-hand side of ship while facing forward" .)
