On a boat the size of yours, you can probably get away with 3/8 or 7/16" lines for the halyards. You could go as small as 5/16" if you're going with a high-tech core line, like a spectra or dyneema cored line, but it would be harder on your hands than a thicker line. 3/8" is about the smallest you can go comfortably.
You will probably want at least three halyards setup—the mainsail, the jib or genoa and the topping lift. In many cases, you'll also have a spinnaker halyard as well. As for lengths... it depends on the mast height. Generally, halyards are roughly twice the mast height, or a bit more if you're leading them aft to the cockpit.
You'll want jib sheets, but they'll depend on the size headsail you have. The larger the sail, the longer the sheets need to be. So, saying what size sails you have aboard her is a good idea. Jib sheets run from about 1.5 times the boat's LOA to about twice the boat's LOA for a really large genny.
7/16 or 1/2" lines might be good for these. Of course, it does depend partially on what winches you have—since, if they're self-tailing, you may need to stick with particular line diameters.
The main sheet will depend on whether you have a 4:1 or a 6:1 purchase mainsheet, the boom length, and whether the mainsheet is an end-boom or mid-boom setup. The thickness also depends on the purchase, sheave size, etc—but for your boat 7/16-9/16" is about right.
As a rough rule of thumb:
- 4:1 end-boom mainsheet you'll want a line 5.6 times the boom length;
- 6:1 end-boom mainsheet you'll want a line 8.4 times the boom length;
- 4:1 mid-boom mainsheet you'll want a line 4.3 times the boom length;
- 6:1 mid-boom mainsheet you'll want a line 5.7 times the boom length.
The outhaul, cunningham, and reefing lines were probably 3/8" or so.
The traveler lines were probably NOT 1/2". That's way too large for traveler control lines on a 32' boat. More likely they were 5/16" or 3/8".
As for running the lines aft to the cockpit, that's a fairly involved project, since you need to add turning blocks to the mast base or cabintop, as well as deck organizers and line clutches, in addition to moving the winches. I'd point out that the mast winches may be a bit small when you are dealing with lines lead aft to the cockpit, since there will be more friction in the system than there was at the mast, and going up a couple winch sizes might be wise and even necessary.
Before doing any of this, I would highly recommend you inspect the sheaves (the pulleys) in the blocks and masthead truck to see what shape they're in. If they're damaged, you can ruin new rigging pretty quickly.
As for what kind of line to use... you really don't need anything more than a polyester double braid. However, using a low-stretch, spectra/dyneema core line for certain lines—like the outhaul, halyards and cunningham—can improve control over sail shape, since the lines stretch very little. They can also reduce weight aloft, since spectra/dyneema cored lines are lighter than comparable diameter polyester double braids and strong enough so you can often drop a line size without sacrificing strength, and reduce windage aloft as well.
CajunRope.com and RWRope.com are two excellent vendors that are fairly knowledgeable and have fairly good prices.
Another way to replace your standing rigging, especially if you're taking the mast down, is to take the rigging off and send it to someplace like Riggingonly.com. They can make up replacement rigging for you and ship it back. I would recommend going with swaged upper terminals and mechanical lower terminals, preferring Hayn HiMod fittings over Norseman or StaLok, since, IMHO they're better and usually less money.

( meaning her ills are repairable ) .and my reason for needing a little help now....i need the sizes of all the rigging . every line on the boat is junk ..and i am not near the boat . so i want to order the materials before i travel down to the boat ,and the lines will be waiting to be picked up...
i need both halyards...main and jib ...but dont know the diameters? the sheets are missing for the jib.... half inch ? or bigger?
the line in the traveler is rotted .....maybe it was half inch also?.....as for out haul ...reefing lines and cunningham .....all missing...so i have no idea.
dock lines also , again is half inch big enough?
I want to run everything to the cockpit to single hand setup........winches are still on the mast ... i want to relocate them to cabin roof.....she does have a dodger to fit in also it was totally removed or never installed for some reason.....do the winches need to be mounted on a wood block ? if so what is normally used ? . if it is teak ...where do i look for that ?. the boat is in st pete fl. ..next I will need a rigger for stay replacement ......i have read about " knothead " ? is this the right guy and right area to find him?
thanks for your help.... Ron
