Harbour for yachts (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
marina
'harbour for yachts' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for marina that I've seen before include "Yacht harbour" , "Yacht station" , "where yachts moor" , "Docking facility for pleasure craft" , "boating facility" .)
