actually the Fox is very well engineered...and much better use friendly as you put compaired to the I-20,,,the Fox riggs up much easier and has a much better downhaul and outhaul system,,The Fox had gotten a bad rap in the states because the fact the US I-20 has a bigger main and a carbon mast,,The Fox hull design is much better for ocean sailing..Mark Murry...drove in the Worrell this year was here for our regatta last feb and made the statemen that the Fox is a much better ocean boat than the I-20.....the Fx-One has much the same set up as the Fox..again the hull design is much better than the I-17 for ocean sailing...the narrow stems makes it easier to tack with just the main and cuts through the 2-4 ft rollers that we have here in the caribbean......so before you go making statement about the Fox or theFX-One you need to know what you are taking about......Harper Jones
