Kirt-
Thanks for all the info specific to the P18! Yes, I have experienced that wild downwind feeling, especially when the rudders kick up over a sand bar while underway. (Almost got introduced to a nearby fishing boat a couple of weeks ago. )

Three questions:

1) Will the P19 rudders fit my P18 w/out modification, or would I have to change the castings as well?

2) Why is a "roll tack" called a roll tack? What's the significance of the word "roll"?

3) When you say, "have the crew get the jib in fast", do you simply mean getting it set properly for new course after crossing the headwind?

Thanks,
Kevin
