For those of you who haven't fallen asleep yet here's a photo of the 2008 ex-Olympic Tornado mainsheet system. Maybe in years to come we'll all be using cascade systems within the boom!
Interesting picture. Any insight on the purchase inside the boom? I'm guessing the dyneema line is routed around a block on the front of the boom and the yellow line pulls its end backward via a floating block?
Assuming something simple like this, 8/1 would be the purchase at the block at the end of the boom, but as the line is coming back to the beam it's adding another length to pull: 9/1?
