Any pictures / suggestions?

I seem to just have a pulleys that end up on a which.  Seems like a X:1 arrangement might be better and help get some tension in my old cruising main! 

Pictures would be good!

No pictures I'm afraid.

Afrita has a relatively unusual Sparlight mast and boom so the following may not work for you.

Our outhaul runs from the clew into the boom around the sheave at the outboard end and is made off on a block within  the boom which forms the moving part of a 2:1 block and tackle.  The standing block is attached internally to the inboard end of the boom.  The second line, which runs through this block and tack, exits the boom on starboard coming aft/outboard and connects to a 3:1 block and tackle mounted on the starboard side of the boom.  The line is made off on a clamcleat riveted to the boom.

This set up gives adequate purchase (6:1) for our main (which is a couple of seasons old).  When we bought Afrita, the line between clew and the internal moving block was wire, I have replaced that and the second line with 6mm (IIRC) Dyneema.

For other suggestion look here (from Harken's website, which is an excellent resource for rigging design even if you buy other kit):

And for other running rigging:

Hope this helps,
