Ok I think this is the last question on rigging. All of you have been very helpful so far, thanks.
When replacing my halyards what size do you recommend? 1/4 or 5/16. My rigging stops at the mast and I have no intention to run it back to the cockpit of the boat. Will 53' for the main and 65' for the headsail work?
If you are running the lines back to the cockpit, are you sure 5 foot extra is enough? I think you need more. I'll check how much extra line is needed to get from the mast thru the cabin top turning blocks, thru the clutches, around the cabin top winch, and enough to tail the line on the winch.
I would recommend 5/16ths or 3/8ths. Even if your not running back to the cockpit, you still will want a bit more than 2x the mast. Your better going 2 times the the square root of your I dimension squared plus your J dimension squared plus about 5. Or more simply put 2 times the forestay length. Your numbers are pretty darn close. After rounding up I came up with 67 feet for the jib. Extra isn't always a bad thing here either. You might consider 75 feet and swap it end for end each year. That way you can always run back to the cockpit later if you change your mind. Plus if you ever singlehand, being able to release the halyard, hold it in your hand as you go forward to lower the sail is always a plus. The length can also help serve as a emergency forestay to hold your mast up under emergency (not under sail)if something happens were to happen.
Same goes for the Main halyard. Up the mast then back to the cleat. That is roughly a measurement of 65 feet with a good chunk to spare. Again, swap ends each year (unless of course you splice in eyes) to lengthen the life of the line. If after purchasing them you really don't like the few feet extra. Cut them, 5/16ths should still be small enough to make reefing lines for the kringles not in the jiffy reef.
IMHO: 5/16"... not too big, not too small. The 65' pre-assembled halyards I purchased from Sailnet were just the right length for leading back to the cockpit.
Mike, Before putting in for the season I had replaced my rope to line jib halyard to an all rope 3/8 line. 5/16 line would have been a better call, in my case. Our jib is a furler and the halyard is run back so I purchased 75'. Since the jib halyard is always taught, I figured there would be some memory or ware at the top where the line bends around the sheaves. That was the inspiration for the extra line that could be cut if needed. I like Duane's idea of swaping end for end. Replacing the sheaves would be the last topic of my recomendation. Belpat Marine(631 205-5167) has the right sheaves. CD's will work but are smaller in diameter.
The original post indicated that the poster had no intention of running his lines aft.
If a furler system operates the jib, I see no reason to waste space by running the jib halyard aft. On our C25 we didn't have jib furling and so we ran the jib halyard aft, plus a downhaul for the jib. On our 1986 C34 I replaced the aft led jib halyard that was running back to the cockpit through the limited deck organizers with a more useful cunningham.
Also depends on the furler. Our furler has a built-in halyard, so when replacing the halyards we left a 1/8" messenger in place of the jib halyard (in hindsight maybe we did not need a new jib halyard which sitting in the boat now) to avoid leaving the unused halyard out in the elements (and reduce weight aloft, I have read).
When I replaced my main halyard, I bought a length of line (75'?) with the intention of leading it back to the cockpit, but I soon scrapped that idea(after the first time raising/lowering the main) because to me it was more hassle than it was worth.
I went back to raising the main from the cabintop and, after lowering the mains'l, I now use the longer tail of the main halyard to wrap the flaked sail to the boom. No more sail ties.
