You are going to keep making me show this picture of my dirty boat aren't you!?

Those are likely for the 'barber-haul' system. Look again at this picture - My system was not necessarily the stock system but the function is the same. The yellow line is attached to a ring that encircles the jib leads. When sailing downwind, you bring in the barber hauler to pull the jib leads to the end of the main beam. This way you can sheet in the jib snuggly in order to maintain good shape while keeping the sheeting angle large for proper downwind trim. I think the stock (or factory upgrade kit) system put the cleat on the same side as the jib. I set mine up so that I could cleat from windward if I was sailing solo.
