Thanks Wouter,
I am very abusive to my boats I think. I don't drag them around but I never hesistate to come in very hot and slide up the sand. I surf and launch waves every chance I get. The 18 has let me down once, broke the front crossbar on a landing double trapped. As I rarely race I most likely fall into the first catagory. Can't get enough power and go head on into whatever. Perhaps the F16 is not for me. A friend has equiped his Hobie 16 with a spin for next season, I will sail it some and see how it feels. I don't think that will compare to a F16 due to the banana shaped hulls. I guess for now my 18 will suffice my need for speed. I am going to give racing another try with this new rig and see what happens. I can't right it by myself so crew is always required but not always available. I will continue to watch the F16 class and see what develops. Thanks again for your time and input
