If we are talking about the same system there is a pic here:

If memory serves me these short lines with loops on each end are attached on each side as follows:
One end is attached to the shroud adjuster in a hole just below your normal hole for your stay. The other end of this small line has a bow clamp thru it. (see the pic on the right) This bow clamp should then be clamped around your stay up above so that you should be able to slide it up and down your stay freely. The quick release pin holds your stay in the shroud adjuster.
Once you pull the quick release pin the stay slides thru the bow clamp until it catchs at the nicopress thimble becuase the bow clamp is too small to allow the end to pull thru. Your stay is now about 18" longer. The rest is the normal righting procedure.
I don't have one anymore (it went along with the boat) but I am pretty sure they only lengthed it 18". If you go too long the mast will be leaning too far and it may want to go back over by itself.
Once the boat is upright, turn the boat so that the wind pushes the mast back towards that side and helps you pull the stay back down and put the quick release pin back into the shroud adjuster ... then your off again!
