Stevie Brewin's undertramp controls explained

Many sailors were intrigued by the 'knitting machine' that was underneath Stevie Brewin and Adam Beattie's Exploder Ad3 trampolines.  So, here is an annotated photo to show what does what.  The undertramp mainsheet cascade system was not actually used in the racing, so you can ignore that bit.  The added apparent complexity is just ingenious use of the takeaway bungees to allow a clear deck, the holy grail of 'A' cat systems. 

Many thanks to Stevie for sharing his secrets.
