Replaced the Blocks with a low friction cascade
on the boom vang



I am always looking at better ways to optimize things and seeing as I had some spare low friction rings I replaced the blocks on the boom vang with a cascade system made of the low friction rings it is lighter, simpler, neater and has super mechanical advantage.The 3 lowfriction rings make a theoretical mechanical advantage 0f 8:1 but with the friction from the rings it is probably more like 6:1, maybe more because I am using slick dyneema. It could even be possible that the the block at the mast base may even make it a 12:1 or a 16:1 system ???? all I know is that it is real easy to add huge downward force  -  feel free to clarify if you know.

The Twin Mainsheets may make a boom vang redundant but the mainsheets and the boom vang make it really easy to trim the mainsail shape in my opinion.
