Re: Main Halyard replacement and re-placement

My main halyard on my P30 is run back to the cockpit. I love it. It makes single handing that much easier. This was done by a PO and he did a great job. The mast winch is still in place and I use it to tension my roller furled genoa. The cabin top winch is a Lewmar (I can't reacall the model number) that is 2 speed without self tailing. The main halyard runs down to the mast plate, through a deck organizer, through a rope clutch then to the winch. I can raise the main without using the winch except to tension the luff. Smaller people can use the winch to help raise the sail. With the rope clutch I do not find the need for a self tailing winch.

The cabin top winch has a substantial backing plate and the headliner is brought tight against the underside of the cabin top. I have no leaks, no stress cracks around the fasteners, and have had no issues that I am aware of.

If you would like more info or pics, PM me.

I'm not sure what you are asking in the bolded sentence. But, if your sheave is U-shaped with a smaller groove for the wire, it's okay to go with all line. The wire sheaves that are V-shaped will cause chafe on the line.

I would think that you can go with whatever size line that you have now with the wire/rope halyard. Probably 7/16".
If you are going to go with high-tech line. You can get away with a smaller diameter, but you should really change out your sheave if you are going to decrease diameter much.

Think long and hard before deciding to run the halyard back to the cockpit. You are adding friction every time you turn the line and you will find it more difficult to raise the sail. Not really an issue if you plan to use the winch a lot. I can raise the main on my boat completely without ever using the winch at all. I couldn't do that if it were run back to the cockipit.

I'm not sure about the construction of your cabin top, but you will certainly want to use a substantial backing plate and be sure that you get no water intrusion in the bolt holes. Otherwise you will likely cause serious damage to the core of the deck/cabin top.
Headliners can also complicate mounting stuff on the cabin.

If you do run it back and move the winch, (which I wouldn't do unless it's a self tailer), you will probably want to add a rope clutch in order to free up the winch. If the mast winch isn't a self tailer, you would be better off just leaving it on the mast and purchasing a new winch for the cabin top.
