National 12 Class Rules

All this discussion about changing, relaxing or deleting rules in their entirety seems rather inane……..   did we not all sign up to a 12ft long dinghy developed within a known set of parameters resulting in close fleet racing at a wide range of suitable venues around the country and sufficient freedom within these rules to experiment a little whilst ensuring the front of the fleet is not entirely dominated by those with the biggest wallets??
 
The rules controlling overall length, beam, minimum weight, sail area, mast height, rise of floor, sheerline et al make the 12 what is….  A 12 foot dinghy, responsive, competitive, fun and capable of being sailed by parent/sibling combination without the complication of trapeze or spinnaker.
 
Statements in various discussion threads that these things are self limiting are misguided, there may be the odd redundant clause but generally extremes of almost any one of the parameters controlled in the rules results in a performance improvement within a narrow envelope, resulting in boats optimised for a certain location, conditions or crew weight combination.
 
I for one do not want a National 13, or a Regional 11.5!! (or an International 14, Canoe or Moth for that matter) The proper place for rule debate is within the technical committee of the NTOA, in a calm considered and thoughtful manner, with due regard for the competitiveness, and therefore value, of existing boats. What will continue to make the 12 an enduring success is not wacky development at the extremes of (or beyond) the existing rules, nor constant tinkering with these rules, but affordable boats designed within a stable rules framework resulting in competitive fleet racing at a large number of venues and most importantly large numbers of us out there on the water visibly having fun; making 12 sailing something others want to get involved in!! That sounds like the class I signed up for, not a class in which the rules could change at any minute making our hard earned and modest investment in sailing completely valueless.

Spot on well done Ian!  It aint broke so lets stop trying to fix it, unless you want to go back to clinker build that is.

Well,  one should stress that the design favours lightweights. Demographically lightweights are on the way out, except of course for adult/child like combinations or (no offense intended) people on the small side. This puts me under pressure, since I weigh in at 95Kg, (am quite normally proportioned at that, so loosing weight means losing  muscle mass :-/).
I want to know how one might be able to increase the competitive range of weight  in the class to include heavier people like myself. It must surely be possible. Were the discussions on this subject, held in camera, or are their any minutes etc to publish?
I already suggested allowing fully battened sails. Not everyone is forced to use them, for those who are often looking to depower. I get the impression that there is (ironically) a certain conservatism in an (even more ironically) development class which is not enabling the class to attract new members. At this rate we´ll soon be losing a few. Let´s be honest, we should be going back to calling ourselves a restricted class, because the same mentality as then apparently prevails.
Sorry to end on such a note......

Very well said Ian.

Jim
Being a development class is not all about constantly changing the rules, nor about throwing out most of those that have given us the fantastic boats that we sail. If you prefer thr tiltle restricted class then so be it - that title hasn't held back a few other classes that we could mention. Yes it would be great to be totally competitive  to the point where you have an equal chance on open water at 95Kg or so - the reality is that to be so you do need to find an lightweight crew - I know I've tipped thescales above that for long enough now, however it is still possible to get some respectable results even at that weight, especially on restricted water whilst hugely enjoying your sailing. Discussions aren't held in camera (though C.A.M.R.A. might be relevant!). Rule changes come about from the members. If you want to see changes the way to do it is by a proposal that then gets considered by the members. We could always add a bit of length, sail area, a spinnaker perhaps, oh and a couple of trapezes and we would have something which would favour heavyweights a lot more but I have a feeling that it just may no longer be considered a National 12!

David, Thank you for your comments. I might come over as a radical, but believe me I'm not.
I am in the process of training up my daughter to be a lighter crew. Yesterday I got the feeling how it might be to be lighter. I went out solo sailing in a 3, gusting 5-6! Everyone was out on the water and it seemed such a shame not to have a go myself, since my crew was doing optimist traiinng for the regatta next week. I passed several interesting boats, including dragons, numerous long hulls who usually beat me in the Yardsticks in the lighter stuff downwind and I even got Passion Pudding to plane upwind! 
I love this class, really. What I don't understand is why, with the demographics on weight as they are, that we don't even it up for the heavyweights  just a little. I don't mean trapeezes and spinnakers and so on, just options on sail area and battens which might make the rig extract a little more power for those who want/need it and for those who might have trouble shedding it, then they might want to stay with what they've got, if they're going fast enough for them and need to depower in the heavy stuff. For those of us who are looking for more power to keep up with the lighter ones out at the front of the fleet, why not investigate this angle? It would make the racing tighter and you'd get more people I'm sure. We should be looking towards expanding the niche, not maintaining its size, or even reducing it (efectively doing nothing).
I can't understand why people talk about increased investment costs. If they are happy with their rig etc. then so be it. I'm sure that the real reason is that they fear that any OPTIONAL changes would result in a reduction in their competitiveness. I've seen here and elsewhere comments about arms races being won by the thickest wallets. The best boats, rigs etc. ARE expensive, but that's the same all over. However, winning races is more about skill and determination. Well I have the latter, now it's time to develop the skill a little more. Maybe one day the class might consider favorable rule changes enabling such options. Then I might shift a little closer to the front of the fleet....:-/
Cheers!

Yesterday I had a Jimboesque eureka moment when I sailed my Foolish singlehanded in a Club race as both of my regular crews (their weight range 9.5 to 10.5 stone approx) were both on duty.  (My weight yesterday was just under 12 stone) Wind Speed was Force 0 gusting 0.5  and the race was a pursuit format.  Because I was sailing a doublehanded boat singlehanded the Club routinely applied a 5% time penalty so I started at +25.5 mins instead of +22.25 mins.  Normally I find the Foolish a bit of a struggle to move in a flat calm on our inland micro puddle but yesterday she absolutely flew (relatively speaking!)and I won the race making an absolute mockery of the additional time penalty, despite taking a wrong turning and having to do a time consuming unwind  The boat felt completely different. and the stern of the boat was noticably higher out of the water with me sat in my helming position for doublehanded sailing.
In my time, I have sailed many other doublehanded dinghies singlehanded in a race, but have never noticed anything like the speed hike as in the Nat 12. 
Not sure I can convince the crews to stay at home when the wind drops every time, but joking aside it seems to me that we may have got ourselves into a bit of a hole optimising boats to win major championships at the expense of other scenarios.  Not sure if it is a good thing and whether or not we can make amends within current rule set.

I think that you will find that the optimum weight is driven by the laws of physics.  12ft is very short to carry much more than 22 stone.  The options to enable carrying more weight are very artificial and would still not be perfect, or would disenfranchise the existing class.  The positive thing is that 12's have different shapes, some suit heavier weights, some lightweights, so the range of competitive weights is quite wide.   Developments in rigs in many classes has moved the optimum weights down, look at Merlins or even Salcombe Yawls!

Agreed, displacement is still dependent upon that ancient Greek. But what options are we talking about here and how would other members of the class be disenfrachised? Why would these options be artificial? Surely, anything other than a change in length (no N11 or N13/14) would be a viable option.

OK Tommo and the rest...
What does clause 5.2.2 say then?

Antony (Guest)

Is there one?  My copy of the rules only has 5.2.1!!!!
 

philipcosson

Exactly, so why:
a) is 5.2 divided into a single subclause, and
b) is there a note about pre 1995 boats being able to ignore clause 5.2.2

Quote from: 40the class rules are fine! try spending more time sailing your boat (and making it go fast!) and less time debating how to make the boat more friendly to your individual needs. this conversation has been going on for years now and i for one am sick of it. oh and sailing more and debating less will probably help with the weight issue!!
sorry if you dont like this but i have had enough!!

Tommo, 
I have never met you, so in your shoes, I wouldn´t assume anything about my motivation, which if you must know is to increase the attractiveness of the class and get more people on the water in a 12. As for your rather personal comments, the only thing that you need to know is that when I´m not on the boat I´m training 4 times a week in the swimming pool and with a regular training time over 2km of 36 minutes - not bad for - probably from your viewpoint - an old duffer of 44!  As for sailing, it´s now up to twice a week @ 4 hours a time. Oh, and the fact that I have to inject insulin as a diabetic is more the reason why it´s difficult to loose muscle mass....
Back to the relevance of this thread (Puke bags provided at the rear and don´t forget to screw up the top - don´t want the place looking like an overturned porridge bowl, do we?)

Please excuse the excursion, I´ve had a long long day....

the mystery of 5.2.2 (for those that care!)
5.2.2 until 1 May 2005 related to transoms (as did all of 5.2)
Effective 1 May 2005 the transom rule was deleted (due to 'popular' demand although we have yet to see the effect.....)
Old rule 5.3 Topsides was then renumbered 5.2, but this rule did not have a subclause 2 so there is no 5.2.2 anymore.  It looks like the explanatory note survived the rule rewrite as any owner of a boat measured before a rule change should not be put out of Class by a subsequent rule change as it has a valid certificate.  ie if you measured your boat in 1995 these need be the only rules that you comply to, if you elect to choose to do so.
It is complex, as were transom rules which were existed in order to make sure we all sailed 12 foot boats and not 12 foot boats with 2 foot transom flaps hanging out the back.
Ed Willett is the Class Archivist (number in the address book) and he may have some documentation about the change.  Alternatively Michael Brookman could probably lay his hands on the AGM papers where such changes would have been raised and explained much more adequately than I could attempt to.
Hope this helps.

I know this is debating is really getting people worked up and I don't want to make it worse.  But I am a heavy weight, 14 stone. I have sailed 12s on and off since a child and having sailed moths and lasers still come back to them.  I have just got another boat and will race it singlehanded until my 4 year old is old enough to come out with me, next year maybe?  Until then I will race it by myself.  At 14 stone the boat absoultely flys and with enough mast bend and grim determination I can sail up to F5, just.  Last weekend I was beating Lasers, Laser 2000s and RS200s and the like on the water, it was great! 
I know the class has a strong history and it is a history of slow development.  It is not the Cherub class!!  If you want to be like them then there is an easy answer, go and get one... they are a very nice bunch.  And I probably will when the kids are a bit older.
In the meantime why not allow singlehanders to attend Burton week.  I know this heresy but look at this way, you may get more people sailing, more people going quick, it can be a seperate competition, no boats get devalued, nobody looses money, no rule changes, just more 12s sailing. 
Whatever happens I will still be out there by myself and I know that if its just me I will never be over weight.  It sure beats sailing a laser!!!!!
