I'm not sure I understand the difference between "boaters" & "sailors".
Could it just be the complainant that the management don't like?
At busy times, mostly during the summer, yachts are not encouraged to come alongside at Orford Quay because it is heavily used by: the Lady Florence for her Brunch, Lunch, Dinner and Sunset Cocktail cruises; the RSPB launch taking folk to and from or around Havergate; the NT launch taking their folk across to Orfordness and back; plus occasional fishing boats bringing their catch ashore. There is always the Orford SC pontoon.
The politics of the NOTT are baffling even to local folk in the know; suffice to say they do not even come near pleasing all the people all the time...and maybe the sailing club folk have more say than the fishermen...
I agree with Lazy Kipper, a combination of the facilities at Orford Quay and the village, and the isolation/beauty of the Butley River was wonderful last year. We struggled to get any signal for ringing home/looking at wind guru, but apart from that a most idyllic area.
The fee for use of a private mooring was worth it IMO.
