Posts: 800 MI | -Interesting posts this week on the old and open forums ,
NAMSA as proposed by Rick is what U S catsailing needs.Please check in there if you hav'nt already .
The Formula concepts of allowing numerous cat builders and different manufacturers to be involved ,is also in line with current thinking .
I,ve observed with great interest the U K cat co ,-which in the last year has helped unify and cordinate catsailing there ,
the benifits will be tremendous for all catsailors over the long term .
-With the goal of providing Formula racing ,-given existing conditions of boat weights and variations of design in the U S ,-BELIEVE the weight to sail area catagory solution in structuring rules is the only viable course .
The intent is to allow all cats listed on the forum previously to be able to partisipate in Formula 20 racing and allow new cat designs to develope within .
Again , if any have a viable rules proposal that can accomodate the variety of 20 ft cats in the U S ,please post ,
If you have suggestions for the weight catagories or other aspects of constructive rules structure , and intend to race Formula 20s please post

Posts: 800 MI | talked at some length with the authors of the F-18 U S rules.
-they have done a very nice job ,and have numerous F-18 specific cat designs to choose from and dealer support that goes with it ,-
AGAIN -we did not create the present set of existing conditions for 20s in the U S ,-we are proposing solutions to remedy these various weights and sail areas in existing designs , often 60 LB crew weights and 20 LBs boat weight variations within the same one design .!!!
Web site =http://www.f18.nl/index.html?Frame_ClassRulesF18.html&ClassRulesF18.html
Other Formula classes use approx 20 sq ft of spin area to 30 lb different weight catagory . -with a jib increase of 6.5 sq ft .
Believe these are a good basis for weight catagory ,though we do sail mainly during summer months in predominantly lighter wind conditions, and would propose placing 6 sq ft differentials in the main in 30 lb increments of weight classification , along with a minimal 2 sq ft in the jib .
This seems to be a proven basis or starting point that may be revised in the classes future.-Will work on substantiating this in design , and refining it further as required .
Original earlier numbers were based on existing designs we wished to include , -but realize they were too far apart.
-Catagory one ,--as compared to catagory 2 Inter 20 class base model at 380 min boat weight , -av 330 crew weight ,-208 mainsail area , 53 jib ,-and 270 sq ft spin.
--Catagory one with an av boat weight or 410 and 330 av crew for a total of 740 would have 6 sq ft more in the main than the Inter base specs. -2 in the jib ,-and 20 sq ft more spin area.
-CATAGORY ONE -wgt=740 spin =290 main =214 jib =55
-CATAGORY TWO-wgt.=710 spin,=270 main= 208 jib=53
-CATAGORY #3 -wgt.=680 spin =250 main=202 jib=51
Cat #4 future -wgt 650 spin=230 main =198 jib=48
-Other rules proposed include the trade of sail area from main to jib only in equal amounts to allow sail plan variation and modification.
-All crews would be advised to target a total weight and sail area below max. allowed ,---full weights will be required rather than half as allowed per other classes as the 20s are a total weight class .
-The 18 and 16 Formula classes have exact specific definitions .
Would like to propose simplified rules in abbreviated form and allow future F-20 members to write more definiative specs , most likely evolving to a modified and developemental trophy scoring system.

Carl should summarize his variable sail area to variable weight boat and crew plan.
Steve should summarize his plan.
Voters would be named via their email and tabulated by a third party.
Email the I20 and Fox sailors who raced last year and ask them which of two proposals they would like or would be willing to race under.
Email H20, P19 mX and Nacra 6.0 NA racers how many would be interested in the upgrade.
Not interested would be an acceptable vote.
Since we have enough interested sailors around the country. I bet we could get a pretty good canvas of the racers.
We should refine this idea and go do it. I will volunteer for a canvas of the CRAC fleet and the Hobie 20 fleet in the mid atlantic / Div 11 and Va beach Area.
Happy holiday's

Posts: 800 MI | Thanks Mr Case , and Mark ,
Taking some time to get the numbers as correct as possible before finalizing Open Formula 20 Rules.
Plan to simplify them to a large degree and encourage and allow more open modification .
-The difficulty is setting an average wind speed which effects boat performance differently in ratio ---that is the ratio may be based at an average 8 to 10 mph , but will not be as accurate at 20 , but all Formula classes use a weight to sail area factor to some extent.
-Again it is a very difficult set of existing conditions that have deteriorated over time, , EXISTING 20 DESIGNS ALL OVER THE SCALE IN WEIGHTS AND SAIL AREAS , dead boat classes ,-Hobiecentric {suggestions AGAIN } ,-believe Formula racing will revitalize the sport over time .
Many may not ,-please forgive me for attempting to understand individuals motivation in posting , some will believe manufacturers one design is the only way to race ,some think Pn rating has all the answers and ,some will post with misguided intent of trying to promote other length catagory F-racing .
-The other interesting aspect is the interest in lightweight design ,spurred on by A Class cat developement .
Ideally we would have 3 excellent UNDER 300 lb 20 ft cats active in the U S to base a class on ,--we presently do not .
This would be very simple if we did .-
As I understand Steve is working on this with a group interested in a Pro Sailing Series , but based in lightweight 22 ft designs ,-
Happy Holidays
Carl

Posts: 195 Texas | Group,
I am working on many different proposals on a semi pro series. As to date nothing other than the corporate structure and the sponsorship dollars is solid. This corporate structure owns the NAF20 class assoc. But, it has always been my plan to roll it over to a non profit and then let it be run by the class participants. Obviously, a proseries can not be governed by the participants and has to be run like/by a business. So the series is set up as a seperate company.
As for Carls formulas I have never been a proponent of varied sail plans. However, I will withhold my two cents worth until his formulas are done.
As for sponsorship, I would be willing to help provide the class funds as long as it falls under the NAMSA umbrella.
I feel that all class assoc. should fall in line under NAMSA and then Namsa can report to USSA via MHC. The pro series will follow this line.
As for basket case -- give some positive feedback and quit bashing everything in every forum. Your negativity and sarcasm is not wanted or appreciated by the people spending their own dollars to make something positive happen. If you don't like something get active, open your wallet and try to make something happen. If you don't want to do that get to the back of the bus and shut up!
Steve

$#@% carl,seems I roughed up your feathers a bit. Why can't you describe me by "some will post in favour of another F-class" ?
Thanks for the qualication "Misguided"
You're weight to sail area is doomed to fail, Carl. It has taken me some 2 years to arrive at what I got right now and I'm still improving prediction. And only recently I arrived at enough accuracy to be dependable enough to base some class rules on. You and MHB want to do it in a fraction of that time ?
Talking about misguided !
Good luck.

Posts: 196 San Diego, CA | Steve - I for one would like to thank you for your efforts to get this class off of the ground. It is rare to find someone who is willing and able to take action to make something happen, rather than just talk about it.
I think your proposals are well thought out, and simple enough to be workable. I think it is important in this discussion for ALL of us to get behind a simple, basic set of ideas to get this thing off of the ground. A complicated scheme, while it might be more fair in theory, is going to turn people off right away. They won't even bother trying to understand it, much less believe that it is fair and equal.
I believe it will be much more productive if we can get started with an 80% solution that is accepted, rather than a 98% solution which never gets off of the ground. Once the class is started and is growing, we can refine it to address any problems which arise. Such refinements will be easier and more productive with the benefit of experience in the class once it is a reality. If we insist on getting either a perfect class or nothing, then we pretty much guarentee that we will end up with nothing.
Sail fast and have fun,
Alan Thompson
