Race performance without cams. The AC-X is developed to be the fastest sail on the water and proved on different magazine tests, without having a wide mast sleeve and cambers. The high-end performance will give you the high speed that you have always dreamed about with minimal effort and easy handling characteristics. Lightness, probably the lightest seven batten no cam on the market, and high-end performance of the sail even further in over-powered conditions. Power and enhanced stability in both low and high wind conditions, combined with a very locked-in feeling, only comparable to a cambered sail.
