It's usually the case, get the rig close to the numbers and then just point it it the right direction.

We've rigged our boat with an average from the rather aged tuning measurements on the RS200 site and that works OK for us.
James Peters in his RS Training vid and the tuning guide he published on the HISC web site never mentioned spreader length. I emailed him a few years back and he admitted he didn't have a clue what spreader setting he was sailing with. He just focussed on rake and rig tension. I guess it goes to show if you are good enough, you are more than fast enough.

I don’t measure the spreader length. I find it better to measure the distance between the shrouds points on the spreader and the distance between the shroud points and the back of the mast , using a batten against the shrouds to get a straight edge. The advantage of this is that the first gives you a parameter to control sideways mast bend and the second gives you one to control fore and aft bend. This keeps it simple -spreader length in itself doesn't mean that much.

Actually, it doesn't really matter which way you measure the length, just so long as you're using the same method that the person providing the measurement used.

Surely depends on your weight, too. As for the measurement place, take each as it comes. RS will have the ball park figure as they measure it, the hotshots/coaches will have theirs to suit. If they don't say, then get in touch, or read someone else's guide.
As said, it will make little difference to be slightly wrong, but it may make the boat feel nicer, and psychologically it can make a surprising difference to your results! |

Also - would not get too hung up on it util you are in the top 10 at the Nationals, spreader length so long as its in the ball park will not make a difference to your placing.

I can find many examples & recommendations of spreader length for the RS200 class. All are typically in the 365-405mm range. However, the RS rigging guide seems to say that spreader length is measured from shroud to the closest mast face. While other tuning guides say from the shroud to mast track. Which is it? |
