I personally don't believe we are looking at a contradiction in the rules. It's more like an OMISSION in the rules. 1.7.2 is clearly intended to permit adjustable diamonds therefore we have omitted to include diamond wires from the 'main' rule summary.

"The rig may not be trimmed between start and finish by other means than sheet, downhaul, outhaul, traveller, mast rotation, [color:"red"] diamond wires [/color] and halyards systems."

Unfortunately, I think this omission can only now be addressed by a resolution at the next WGM. The F16GC now need a proposal and a seconder for that proposal so that it can be put to the membership NOT as a rule amendment but as a rule clarification.

Thank you MarkP and macca, I think you are both quite correct in pointing out this minor drafting error!

The rules are clear but the text on the website at the "F16 Class Rule Summary" page is not.

Maybe line in question should read:
"The rig may not be trimmed between start and finish by other means than sheet, downhaul, outhaul, traveller, mast rotation and halyards systems with exception of diamond wire tension."
or something like that.

edit:John beat me to it.

Hey Mark,
You wouldn't be [censored] stirring would you?
Too cold to sail?
Don't tell you've run out of beer?

I agree, it appears that in intention is to allow adjustable diamonds. Needs cleaning up.

Andrew - why dont you get a boat sorted for the container going to mumbles.?

I know a good builder!! <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

can you make it 80kg and 17ft long? <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

Minimum weight gauranteed <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" /> plus you dont need 17ft on the "OzBlade" <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />

I think there will not be a lack of volunteers to make it "compliant" <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

Mark,

You are refering to a summary of the class rules and not to the real class rules.

I seem to remember that the summary is explicelty conditioned as being subject to the full class rules taking precedent when conflicting. At least it was that way on our old F16 website where I had made the summary.

Wouter

that would make it overweight and under length for an A.. Still it would measure in..

Best of luck against the A boys... <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

Marcus and others,




Actually, it isn't up to them. Rule 1.7.2 was included in the class rules in 2002 after the general acceptance vote that also explicitely allowed the adjustment of the diamond wire tension DURING racing. As such there is no situation of intepretation.

This vote was a direct result of the fact that some of the Bim 16 boats at the time were said to have this setup and the fact that we analysed it to be an inexpensive and possibly advantagious setup. We reasoned that if it is inexpensive that there is no reason to exclude it from the class.

We don't see this setup very often in F16 class as its benefits require very good understanding of how the rig behaves and the risk of setting it wrong and only make performance worse is very large. The subject was researched in the early years of the F16 class using input from skilled sailors like Goodall, Anderson and others; as well as researching the performance history of this setup in the A-cat class where is found more often.

There is no conflict in the class rules, we have only found a small misalignment between the official class rules and a (quick and dirty ?) summary of the class rules. Of course the official class rules always take precedence over any derived summaries etc.

In my opinion the summary is not part of the class rules (never was) and can as such be altered without any official AGM or voting procedure.
