[quote=Dogboy]Without a picture of what you are describing, it is hard to know for sure, but I would say it is either one of two things:
1) Something custom that a previous owner created (possibly some type of mast rotation device or other gizmo). Definitely not something stock.
2) A barber hauler system. The very, very, very early Hobie 18s had a "barber hauler" system for the jib. The system had lines that were connected near the midpoint of the boom at one end with a cleat, and each end of the line had a stainless ring that ran out to the jib sheets (between the jib blocks). This allowed you to pull the jib sheet farther inboard (i.e., close the slot).
I don't recall ever seeing this system in person as it was quickly abandoned and no one uses this system anymore. If your boat is from the '70s, I would guess that is probably what the part is you're referring to. If this is what's on your boat, I would remove it. As I said, it is something that was quickly abandoned by Hobie.
