I'm setting up my (new to me) 8.6 for the first time and am a bit puzzled by the lines inside the boom. The middle one, obviously, is the outhaul and the the two lines flanking it appear to be reefing lines but I have not been able to figure out how they should run. There are two sets of reef points in the mainsail but no blocks or cleats on the boom or mast that would seem to be necessary for rigging a jiffy reefing line or lines. I'd be grateful for any suggestions.
