I have a modified P18-2 and have a 3:1 at the boom end connected to a 4:1. It's about a 12:1 with much simpler blocks. I used the same system on my P19. years ago, before the synthetics, I used 1/8" 1x19 wire on the back end. A friend borrowed my boat, went to jybe by grabbing the mainsheet. It started moving before he could grab it and the wire got his attention. He didn't get hurt, but I got an ear full. I just know in breeze, I have to be very quick to stay ahead of the traveler coming across.


Cheers...
