The reef. line is tied around the boom at the aft end. Each is threaded through its respective block on the sail then back to the sheave at the end of the boom. then the lines are led through the boom to the forward end. Fom there the lines go up through their respective blocks on the sail , then down through the turning blocks at the base of the mast, through the line organizer to the spinlocks at the top of the cabin.
The outhaul lline ties to the clew, is led around the third sheave at the back of the boom, through the boom, around the sheave. at the front of the boom and secures to the cleat at the starboard side of the boom. I have changed mine so that it is also ru back to the cabin top at the cockpit.
This is the way my 323 is rigged at least. Hope this is of some help.
