[Rhodes22-list] CDI Furler Wire Halyard Snapped - What's at the top?

I would think the topping lift line would work to check the meat. It may be possible that the pop top was broken by someone walking on it. I have a stress fracture in my slider top from that.

A conventional mainsail rig can use the main halyard as this line.  On an IMF mainsail rig, you will have to tie a line to the masthead casting somehow.  If you find any bend, you will have to ask Stan how much bend is acceptable and if the bend can be safely removed.  My guess is, if the bend is beyond acceptable limits; then, you probably won’t be able to fix it.  The reason the mast probably won’t be repairable has to do with how the mast is made.  Our masts are made by extrusion from 7071 T6 aluminum alloy.  After extrusion, this alloy has to be heat treated to make it stiff.  But, the heat treatment process also causes the alloy to be susceptible to cold work hardening and embrittlement.  If the final mast extrusion has been bent by an impact loading, the impact site will be cold work hardened.  Bending it back will probably crack it.

I've noticed a couple times that the mast may not look straight - it's pretty close, and I convince myself it's an optical illusion. It seems to hook back an inch or so part way up the mast. We had a cherry picker at the boat club last weekend, so I went up there to look at the top of the mast where the toggle fork failed. Looking down the mast, I believe I could see it hook backwards slightly, and that may be why my mainsail has never furled well. I have to pull down on the clew pretty hard to get the mail to furl. I do not see any damage, e.g. dents or otherwise, to the mast, and it doesn't appear torqued. I have no idea what the previous owner did as far as changing out any standing rigging, but maybe something broke a while ago and didn’t get the lengths quite right.

I measured this 6 times, and 3 times I came up with about the same measurement: 28' 1-3/4" +/- 1/8" center to center. Just to clarify, the distance from the center of the pin that goes through the chain plate to where the toggle fork broke is 28' 1", then I added 3/4" for where the piece broke off to where I think the pin would be. The forestay wire is 27' 6-1/4" (taken to the outer edge of the swage crimp). I really think I'd run out of adjustment on the backstays if the forestay was about 3.5" shorter. I'll go back out to my boat, but I'd be surprised if there was more than 1.5-2" of adjustment available on the backstays.

The hull was coated in mineral deposits, which I continue to work on. But then our lake water isn't much better.

Again, this is the distance from the center of the pin holding the headstay to the masthead toggle to the center of the pin holding the furler assembly to the bow chainplate.  This measurement sets the overall tilt of the mast and it affects the weather helm/lee helm balance of the boat.  Making the forestay longer tilts the mast aft, moves the center of effort (CE) of the sail plan aft, and increases weather helm.  Conversely, making the forestay shorter tilts the mast forward, moves the CE forward, and increases lee helm.  If you think your R-22 has too much weather or lee helm, now is a good time to fix it.  Realistically, you can only change a few inches +/- from the above measurement without running into other issues with your standing rigging, like running out of adjustment on the backstays and lower sidestays.  But, it will have a noticeable effect on your weather helm/lee helm balance.

For example, S/V Dynamic Equilibrium is setup to have neutral helm in light air, slight lee helm once the angle of heel gets > 10 deg, transitioning to neutral helm, and then slight weather helm as the angle of heel increases.  Neutral helm in light air is OK because you’re going so slow you don’t have any steering feel anyway.  Going from slight lee helm to neutral helm back to slight weather helm as the wind speed increases means you are having to use much less rudder correction, which adds drag, and the boat has less tendency to round up in a moderate puff of wind.  But, by the time you are putting the leeward rail in the water, you want weather helm and a tendency to round up in a gust because it’s safer than lee helm or neutral helm.  As you might imagine, it took a lot of hours on the water to fine tune this setup.  But, I’ve owned my R-22 since 1987 and I lived on a lake.  This is how you set the mast up for racing.

I am certain I have that measurement written down in my Harken Roller Furling manual because I had to specify it when I ordered the new forestay from Harken.  I upgraded from the CDI furler to a Harken Unit 0 furler many years ago.  The Harken furler has upper and lower swivels in order to take full advantage of a foam luff pad on the genoa.  When I get home, I’ll look up the measurement and forward it to you.
