Curious that you don't accept a comparison to boxing but you do accept a comparison to baseball.....

"WE DON'T SEE THINGS AS THEY ARE, WE SEE THINGS AS WE ARE." (Anais Nin, 1903-1977)

Glad you got it, it took me very a long time too when they tried to explain it to me, (and sometimes I still forget and make the same mistake!) The 1 to 3mm difference sounds about right, and I think it's probably important, along the length of the whole leach it would be a few square centimetres ex...

I understand the issues concerning the 1/4 1/2 and 3/4 leach measurements. To do it on a real sail, folding is necessary to determine these points. Assuming that the leach is a straight line between the head and clew, this could be done with a ruler. Folding the sail will give the same locations. I...

They are accurate assuming the leach is maximum dimension. This is no good I am afraid. I have measured quite a lot of sails over the last few years and can gaurantee you that minimums are used for a significant number of sails. The leach points are defined not by batten position, but by the actual...

To add a few grams more salt to this discussion: If you weighed and certified your boat you would need to change the weight rules no? e.g. at certification my boat weighs 4005grams and the keel 2495 grams.All legal,. At an event my boat still weighs 4005 grams but the keel only 2210grams. This is le...

And carbon spreaders - they are now appearing at events and people are asking if they are legal. I can't see that they are not since, as we have stated, materials are not even mentioned. I think it worth while clarifying the issue one way or another. Roy Thompson Rules and Measurements Officer ESP I...

Are carbon spreaders allowed? I can't see anything about materials for these items (optional mast fittings in 5.3.3.b.5) in the rules and they have started to appear on some boats.

Bruce said This brings up another point - perhaps we should compile some sort of common measurement procedure that all official measurers use to certify rigs and hulls to assure uniformity in the process required to get a rig or a hull "stamped". I think this is called 'Measurement Forms' Bruce... S...

the answer is to certify the hull (which is all that the form really addresses anyway) and not check any of those boxes. It doesn't really say they need to be checked That is basically the interprpretation of 2005 of IOMICA. BUT - the certificate itself says you can only race with the rigs shown on...

I think you may be missing the point. On the 'certificate' (which clearly identifies and relates to the hull) there are three boxes, one for each of the 3 sized rigs. There is no way I can see that an 'extra' rig can be added without removing the first rig. It says 'tick' the boxes, not 'state how m...

Is it possible to measure 2 No1 rigs (for example) and add them both to a single current valid or new certificate? If not, what specific rules prevent this? I can see that if you are transfering rigs from one boat to another they would be removed from one certificate, but can they be added to anothe...

Ken,
Are you saying that you know that this hull has a metalic paint finish that lets the fibre show though and imitates Texalium or are you just making a less informed guess?

Thanks,

Can anyone tell me the hull material for Jeff's AUS14 at the worlds please?

It looks remarkable similar to Texalium in the few fotos I've seen but I am sure it isn't.

Good Sailing and keep it clean guys!

Thanks Andy. The measurements forms I have alrady downloaded so I will await the Certificate.

Is there a 2007 certificate with a set of Guidelines??? With the new 2007 class rules and measurement forms it seems logical. I have to measure boats next week and as ESP NCA officer for Rules and Measurements I need a copy of any new certificate or specific instructions stating that the old 2003 ce...

Measurement Mike Eldred Has been co-opted as VC Measurement, he’s currently getting up to speed with measurement issues. It’s worth noting that there are also vacancies on the measurement sub committee for willing volunteers who wish to make a contribution. Funny that, I have not heard a single...

Barry, As far as I know there is no defined proceedure for using the water tank for draught measurement, OK? We are not profesionals, and the variety of designs of watertanks (those that I have seen) would not all allow a set proceedure. That said, I hope that all event measurers use a bit of common...

Some very brief comments: If you need to measure the waterline at any stage, you need by definition, water, maybe not a tank as we know it now, but a body of still, fresh, clean water. Comments from measurers in other classes (both r/c and larger classes) have led me to believe that measuring/markin...

It just seemed strange that the class is practically begging for volunteers, and you have a person that is willing to take the job, and the vote was nearly 50/50

I can do nothing but agree with you completely Steve.

I don't suppose it would be as simple as giving the position to the candidate that lost? I know there are certain people that think this is not wise and personaly i am somewhat inclined to agree that it may not be a good idea. Since we don't know why people voted in the way they did (against the lo...

lol.

What is 'lol'?

Thanks

Fantastic work Charles! I see that they also export, great! (No doubt the Euopean Union will have something to say about wood exports from the USA). I normally buy about 45 (or a few more) strips of 10x3mm (x1metre) to make an IOM, this gives me enough spare strips to choose and get a nice colour ma...

Present measurement rules wouldn't find the substrate

Could you explain this please Rob?
Thanks

Thanks a lot David, much appreciated!

In my opinion and based on experience in the Exec I would say that the VC Tech post will need a strong team. There are still a lot of Tech questions pending after the worlds voting as well as a bunch more in the pipeline I suspect and they are going to take some careful looking at to get right. Also...

We need a well balanced Executive I believe a 'well balanced' Exec should try to include members from all parts of the world not only 1 or 2 continents/countries. I realise that this is not always possible when there are so few candidates. I reiterate that I am willing to help out on the Measuremen...

I understand there is a 'candidate' willing to be co-opted for VC Measurements. What is the official proceedure for this and for the 'removal' of the current VC measurements. Should not the names of these possible candidates be made public so all can give their opinions?

And if you're not using cedrela odorata, then what (scientific name) do you use for planking? Ah my friend, if I knew that I would have put it in the post. It's a mystery which I continue to investigate. It is sold as 'Galician Pine' which may well be a type of 'pine' that has been treated and that...

Charles said: If Roy Thompson is talking about Spanish Cedar (cedrela odorata, not really from Spain, but imported from Brazil or elsewhere in SA) then it's not the same as Western Red Cedar (thuja plicata) . 1)No I am not talking about Spanish Cedar. No such common name exists here anyway - see 2.)...

In my experience (and it's not so great so listen to others) the problem of cyano isn't as bad with the harder woods but excess glue can leave an aesthetically unpleasing 'stain' which looks a bit ugly and is difficult to cover up. With epoxy, it's not generally so bad since that's the same as your ...
