It's easier to replace the halyards with the mast up. Connecting the old and new halyards together allows the new one to follow the exact route of the old one, so you know you won't foul the VHF antenna lead or the electrical wiring in the mast.Now, if the connection between the two halyards gets hung up at the sheave you will be in trouble. This is what happened to me, and while I was trying to free the halyard, I broke the connection and both halyards fell to the deck.Now I have to unstep the mast, fish the halyard through with an electrician's wire gizmo and then check to make sure I am not fouling any of the wires in the mast. I think the people at the marina are going to have a first-hand lesson in why sailors have a reputation for colorful swearing.PeterS/V Raven
