I have installed quite a few rigs on yachts over the years and can only confirm that, without exception, those concerned reported superb results. You do not have the exclusive to this type of work. If you do not agree, simply say so, and keep your banal remarks to yourself.

I'm afraid I find you a rather unpleasant, 'know-all' character, so will place you on my ignore list as, I believe, many others have recently done.
