I just got my FX-One and I am very pleased with it.....the hull design is very clean and the low profile on the bows works very well here in Caribbean..where we get some pretty good rolling seas...it cuts right through the waves...its faster up wind than I thought it would be and faster downwind ..the downhaul is a great set up just like the Fox and the mast rotator line runs under the tramp to the hulls..very easy to make changes downwind.......another beachcater here has a I-17 so we can train together and see how we fare against each other.......
