I'm just wondering if anybody out there has already done this, similar or has any thoughts thus having any pro's or con's for what I am doing? This is another project I'm doing which is fitting a stack pack system. The bag I've had made is of a conventional type. I've done a jury rig Stb side with the lazy lines tied to the boom in the approximate positions of the bag. This is my idea for bringing the lazy lines to cow horns on the boom end so I can adjust from in the cockpit, and it seems to work. Of course the main reason is to prevent another journey to the mast. It's not at all a conventional way but it goes like this and hoping you can follow this. Still using the mast pulley blocks, the line carrying the pulley block that the 2 forward lazy lines go through, this goes forward way around the mast pulley with the line leading out aft with another pulley block on the end of this line. Then the line that goes though this pulley goes to the 3rd lazy point with the bitter end going to the cow horn cleat on the boom to tension from this point. I was thinking of temporarily fitting a short shock cord via the cleat as a safe guard just in case it over tensions. Feel free with comments either way.
