Back Stay

I have noticed that some of the newer MKIII 27's have a split backstay with two "chainplates" at the transom, on either side.  My '76 MkIII has a single chainplate in the middle.  I would really like to convert.  Can anyone offer any advice? Has anyone else done this?  If any pictures exist of the reinforcing required to move the chainplates to this outter position they would be really helpful.

Re: Back Stay

Chris:
My back stay was converted perior to my owning the boat, thus it retains the original centered tab plate on the deck as well as having the tangs outboard on the rear deck. Yes, they are reinforced under the deck with small plates.
I have a back stay adjuster which snugs down the split stays and bends<img src="emoticons/icon_question.gif"> the mast and tightens the forestay.   I have raced my boat in winds up to 37 knots and I can tell you from experience that the adjustment does not do much.  In medium to light airs it actually will slow the boat down.  I have found that the C&C 27 MKlll likes to be sailed loose.  It does though help with head room when standing at the wheel.

Any sailmaker rigging shop can set you up wiht the parts you need as well as altering your current back stay.

Best of luck,

Re: Back Stay

DHM, I second your opinion.  The old 27's mast is like a telephone pole and not really meant to bend much.  If you were serious about flattening the sail, you'd need a newer, bendier mast.

Re: Back Stay

I totally disagree with the coments above, The mast were meant to bend and that's why they do. The C&C27 came both ways, single back stay for cruisers and split for racer cruisers. knowing when to use back stay is another thing to deal with along with how much to use and in what conditions to use it. Harding up your back stay is not for going faster, but more for pointing ability, I notice a lot of people tighten there back stay and begin to over point and loose all there speed, your split back stay adjuster also works well on the down wind legs buy letting the back stay off completely and attaching a fraculator for the down wind spinnaker legs. It also makes a big difference for comfort if you wish to set at the stern. Prebend on a C&C 27 mast should be six inches. After all this if your main is not flat enough then it's time for a new main or a recut.

Re: Back Stay

A fraculator is a strap that is approximently a foot and a half long that is attached to the bottom of your forestay, on a down wind spinnaker run you attach your jib halyard to it and losen your back stay adjuster of and tighten the jib halyard which will bend your mast forward.

Re: Back Stay

Gee, BOB
do you use that fraculator on a regular basis?

Re: Back Stay

Fraculator?

Bob, that's gotta be "Legacy-speak" or at the most charitable, "ABYC-speak", because not only have I never heard the term, I've never heard of anyone hauling the masthead forward, nor even expressing the need to do so.

It sounds like your foredeck guy has been upholding Parkinson's Law with a little task inflation -- is it safe to assume that he's a provincial bureaucrat when he's not sailing?

Re: Back Stay

We use it in regatta,s, especially in light air. We don't practice this in club racing, not worth the time or effort. And Gee Jim it really works!

Re: Back Stay

In support of Bob's claim: Larger boats, such as J-35's, use fraculators as described to good effect.
