My
jib halyard jammed and broke at the swivel of the roller
furler at the masthead. I hauled a helper up who ran the wire portion of the
jib halyard back through the sheaves of the masthead but afterwards the genoa hoisted with great difficulty and I can''t get the main up at all. I do not know what the masthead layout looks like so I do not know how to explain to my helper exactly what to do. Does anyone know where I can obtain diagrams of what the masthead, sheaves etc look like or I need instructions as to how to run halyards to fix problem without lowering the mast.
