The cleats at the base of the mast, however seem to be mounted upside down. Intuitively, it seems like the halyard(s) should routed thru the cheek block so that you're pulling up on the halyard to raise the sail. Then, the halyard is locked into place using the cleat (mounted above the cheek plate) while still pulling up on the halyard. The cleats on my mast are mounted so the halyard are pulled down to lock in the line. They are mounted above the cheek blocks. It doesn't seem right. But, I am a beginner and know next to nothing about sailing.
It's a 3:1 jib halyard tensioning system. The "line" portion of the jib halyard is led down, thru/around the cheek block, thru a small block (mine had a becket) at the end of the wire portion of the jib halyard, and back down to the cleat. See if there's a "mystery" block in the jib halyard that ends up a couple feet or so from the mast base when the jib is up.
I had an eyestrap on the front of my mast to secure the loose portion of the main halyard.
