Mother and artist welcoming popular boating facility (6)
I believe the answer is:
marina
'boating facility' is the definition.
(I've seen this before)
'mother and artist welcoming popular' is the wordplay.
'mother' becomes 'ma' (ma can mean mother).
'and' is a charade indicator (letters next to each other).
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'welcoming' is an insertion indicator (in sense of 'inviting in').
'popular' becomes 'in' ('in' can mean trendy).
'ra' enclosing 'in' is 'rina'.
'ma'+'rina'='MARINA'
(Other definitions for marina that I've seen before include "Berthing area for yachts" , "Yachting centre" , "seaside area" , "Yacht station" , "Dock for yachts and cruisers" .)
