Tim,
I tried the 8:1 jury rig set up but found that the pulleys on the rope ends got caught on things like the spanner mounting or got too close to the diamond wires. <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" /> Also found that I needed too much rope to feed onto the upper section just to reach around the path then tie off onto the end pulley.
Once I go the downhaul working the rope could be shortened significantly. Maybe I had the upper rope section too long.
I reverted to my normal setup (non cascade) with a bit of concentration in putting the ropes through the right pulleys and found a marked improvement in performance. I even had the leaders in sight for the whole race. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
Will try it again next week.
Regards,
Peter
