I accept that I am an idiot. I have now read most of the posts in this thread. I now amend my post and will say:

I hope that the rules for a fair F20 class are ironed out soon and that it includes many different types of boats and that many races are scheduled. I look forward to modifying my I20 to be competitive with the best sailors and working on my sailing skills so that boat speed is put to good effect. PS.. if anyone wants to sail from Corpus Christi to Houston on july 4th & 5th I am putting together an informal race.
