A C&C question? on spreaders

Why do my spreaders have a single pin in the middle of them? Are they movable? Like, to take tension off them if I use the backstay pulley pensioner? Not sure. Let me know if you have some information on this topic
Thanks. I will trade ya for a great drink.






The Backstreet Bushwhacker



1 ounce of Vodka

½ ounce of Amaretto

½ ounce of light Crème de Cocoa

½ ounce of Kahlua

1 ounce of Bailey's Irish Crème




Blend with ice cubes until it has the consistency of a milkshake.

Sprinkle with nutmeg.

Re: A C&C question? on spreaders

Spreaders are often on rotating mounts to help absorb the angle change that can happen with varying amounts of mast bend - probably most often when that mast bend is induced with a baby stay, which yours might well be....

Thanks for the drink.. but I've just gotten around to losing some weight, so I'll just make that one for guests....

Re: A C&C question? on spreaders

My back stay is split like 1/2 the way down and there is a set of wheels and a single wire coming off of it it is so I can adjust the mast? I guess

Re: A C&C question? on spreaders

The pin is just there to keep the spreader from rotating. The other end is notched to accommodate the shrouds. If the shroud slackened enough the spreader could rotate or even, unlikely, come out.
The thing on your backstay is a backstay adjuster. The C&C 30 has a masthead rig, and the mast won't bend, but you use the backstay adjuster to tension the forestay while sailing. Tighten it when going upwind to reduce headstay sag (keep the luff of the jib straight), and loosen it off the wind to give more fullness to the headsail.
I'd recommend a rig tension gauge to check your forestay and backstay when using this. At the beginning of the season, after the rig is tuned, I tighten the backstay adjuster increasing amounts and record the backstay and forestay tension at each setting (forestay tension will be a little higher than backstay due to the angle, so I use this as my setting). I then mark the adjuster at its maximum setting (I use about 15% of breaking strength for my maximum tension) so I don't risk breaking things when I'm really pushing the boat hard. I recheck a couple of times mid season because things stretch out.

Re: A C&C question? on spreaders

Just because it is a masthead rig doesn't mean that it won't bend. My masthead rig bends quite a bit with just backstay tension, and even more so if I crank on the babystay as well. Of course how much the mast bends depends on how stiff the mast itself is, and whether it is tapered or not.

Re: A C&C question? on spreaders

I agree. However, The C&C 30 mast is a 4x8" untapered telephone pole. You'll fold the boat in half before you bend the mast, so I was trying to explain this in terms of forestay tension.

Re: A C&C question? on spreaders

Thanks for your help.Im learning a lot. I do have a tuner for the boat just not sure if it is correct for all boats. It looks like its just for a dia. of wire then you pull the lever to a set mark and then read were is should be? If it is needs to be tighten then I tightren it. I have done this.
Thanks a gain for your help. And I will fly a jib at the dock and try to use the back stay adjuster and pull it till the luff comes out.

Hence the C&C smile.

The backstay should be harden to adjust foresail luff tension when underway. Adjusting it at the dock does little. You should also ease off on the backstay when docked.

Re: A C&C question? on spreaders

Thanks, i'm going out next weekend if the wend is in order. I will try to shape the luff while under sail.
