[quote=scooby_simon]If you do not want to go internal to the mast; you can have a cascade 16:1 externally



Scooby,
It looks like you've replaced the micro cheek blk at the very base of the mast aft, with something larger, what prompted that? What is that blk, I don't recognize it? A wire blk? How about the red twing ball in the blue line, is that your way of terminating the blue line after it's been fed thru the blk(s) at the mainsail tack? Nice! Is the red line 3/16"? Which line(Mfgr)? Thanks for the pic and post!
