Thanks for the info. I've not been on another Rhodes, but I've spent considerable time on a Capri 22. Based on that, I'd say my boat has excessive weather helm, and I really appreciate the info you provided.

I've not made any adjustments to the forestay assembly, and the only thing I'm guessing on is adding 3/4" for the piece of the toggle joint that broke off to the point where the pin goes through. 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.

You also mentioned chloride stress cracking fatigue failure. The boat was a one owner and came from Wisconsin and had a Wisconsin title, and I don't know if it was ever sailed in salt water. The hull was coated in mineral deposits, which I continue to work on. But then our lake water isn't much better.

I worked on this email far to long, but I'm hoping it's relatively clear to understand.

Hi Allyn,

The pin-to-pin forestay measurement is 27 ft, 9-5/8 inches.  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.

It’s almost impossible to have neutral helm throughout the wind range.  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.

Allyn,

The measurement you need is from the center of the pin at the masthead to the center of the pin at the bow chain plate.  I’m due to be released from the hospital tomorrow evening.  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.

Over the years, I’ve replaced nearly all the standing rigging on my boat.  I like the West Marine rigging service.  Look in the back of their catalog.
