Beneteau 51', sadly I have no pictures and the boat is too far away at this time, but maybe this description will suffice.
Exiting the boom at the mast and running inside the boom all the way to the end where they exit are 3 lines
is the out haul. Works as advertised
I assume are the reefing lines
One line is not their but their is a space for it.
I am accustom to reefing lines ending on a block mounted on the side of the boom underneath the appropriate reefing point on the sail.
With the reefing lines run to the far (clew) end of the boom the angle of pull does not seem to be optimal for shorting the sail.
At the goose neck end of the boom where these lines exit their are cam style dogs that don't really work right as I was unable to get them to clamp shut. I'm thinking that the lines are a little over-sized so the cams don't work.
How should this be rigged?
