Your halyard almost certainly has jumped off the sheave and into between the 
cheekplate and the sheave. Depending on how hard the halyard has been yanked 
on after jumping off,  it's possible to get things straight by bosun chair. 
there is an aluminum plate above the sheave assembly that is removed (it's 
held in place with sheet metal screws I think), then you futz with the wire.

The fix is to drill and tap for a machine bolt (with locking nut) into the 
mast adjacent to the cheek plate. If your main halyard winch is on the port 
side, then the port side is best- the whole problem starts by not having the 
halyard leading straight up the center of the mast. Anyway, you then screw 
in the bolt until the cheekplate is forced against the sheave; then lock the 
affair in place with the lock nut that you have remembered to put first on 
the bolt.

Been there, done that.
