I have had my new CDI develop a twist in the luff. CDI suggested that I stored it wrong on the mast over the winter. They did send me another. Within 2 months, the new one developed a twist. CDI did send me a second luff, after several calls, and many months. I have not installed it as yet. I sent out a message last year , and 2-3 owners of the 24' or 26' water ballast complain of the same twist. If you experience this problem, contact CDI and Hunter Marine.
