Mark, Thanks for the replys. But my question is not getting answered. How about this... when I sail my 16 with my group I am faster than everybody 16s and18s. When I sail my 18 I am faster than everybody. (everybody singlehanded on the ocean)According to the ratings the 18 is supposed to be faster. Maybe Im good or I need to find other people to sail with. Under whatever rules there are which boat would have a better advantage. From what I am trying to figure out tonight the 16 would.Thats why I really what to enter to see how I do. I just did not realize this was so complicated. Again thanks for your time.-thomas
