Wouter I agree it is more of a perception than reality. I look at the time to set up the 20 as double that of the 16. There are varying degrees of busting your boat down that we don't need to hash out here (please?). Adding a spin to rig time varies from 5 to 30 minutes (depending on who you ask).

At last years Mid-Americas I witnessed (for the first time) Tigers "flying" downwind and thought "Damn...why aren't we ALL doing that?!?"

If the ladies, daughters and sons can handle the front end of a 20, they can also handle a spin...again perception. A Tiger with a self-tacking jib only and no spi would be like a step back to riding along on the 16. HF18SN (tiger no spi) 63.65, still faster than a 20. <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />

Pat I like your idea of allowing MM F18's starting with Tigers. That leaves a lot of choice for product to put on the race course.
