You are not G-d? You are a catamaran sailor, and a captain.

Short answer: yes. Long answer:
(1) place to put it (problem)
(2) reasonable price (check)
(3) permission from momma (pending)

I still would like to discuss whether we need to consider the minimum weight issue and the minimum crew weight issue.

Also, I personally like the idea of opening the class to innovation. For instance, if you want carbon boards, go for it. If you would like to try to retrofit some bannana boards, make it happen.

While the sail plan is the launching point for this class, making it an Open class should drive interest and development.

Well there was some good work done this week as far as sail measurements go. Kevin Rajida and hunter from schurr sails get all the credit for this. Kevin and hunter have been working on getting all the data they can over the last few days.

Should we have a sail measuring party here at our club? Was thinking of doing this anyways, since one of our members will be contacting a local sail maker this week for a new sail...

The unraveling has begun...

How are you guys measuring the sails? There are a lot of different ways to skin that cat. The F18 rule is pretty detailed but works well to control the "creativity" some people seem to find with sail measurement systems. Be glad to help with some insight.

Are you going to post the measurements somewhere for all to see and use or is this just a Schurr thing?

They seem to want a lot of development. 320 lb boat weight and a max sail area of xxx for the sail plan.

I would think any standard method used by sail makers would work.

I would love to hear how the sailmakers will manage the super stiff telephone pole that is the N20 carbon stick. Can you get the range needed without pulling the sail apart in a year.

Perhaps one of the load path sail cloths could let you bend the mast enough.

If you guys get any measurements on the bend of the sticks... it would be interesting to compare with the alu N20 stick and the F18HT riba sticks or the Tornado carbon stick.

Always looking to learn something.

Nice! Couldn't you guys just borrow someone elses system and plug in your own numbers?

We (Hunter Riddle and I) have been using the F16 documents to measure the sails. This was what Hunter used when he and Mark Smith started developing new sails. As we get the rules for the new class firmed up we will post the measurement system. The idea is not to have to measure every sail but to give sailmakers the ability to measure and mark sails with the size. I will also publish what we find measuring existing EP sails as well as the one's Hunter has built. I have measurements for the Europe sails that Charlie Trinque has as well as several sets from the 1000 series (Alter Cup boats from 2006). Hope to get hold of an older one that Charlie Harp has soon (USA496) just for comparison.

Kevin, do not forget to include the mast in the sail area measurements. Since Charlie has the wing mast and everyone else has the carbon stick it makes a significant difference.

Knew that, going by his house this afternoon if it isn't raining to measure the stick. Gonna stop at PYC to measure a carbon one that is on a trailer next day or 2.

Kevin

Make sure you understand the spinaker measurement. You could end up altering a perfectly good spin. Don't ask...

Speaking of width and light weight... CFR20 is 8'6".

Narrower "can" be fast. A 10' set of beams has been talked about, however.

Kevin:

If you need to remeasure my main (#483) or my new Schurr sail, I am available at your leasure. Thanks for being an important part of this process!!!!

Also, as Captain Cardiac has indicated....the insane 20 Caballa has taken everyone's advice and are in the process of updating Version 1 of the Class Rules including the appropriate change from F20 to O20. Climb on board folks, the train is about to leave the station. Please keep your productive ideas coming (excluding any "you suck" or similar ones). I am hopeful that this class can invigorate the 20 platform.

Love,

I see one small problem.
The only boat that fits is the N20. Would you race an older design (Nacra 6.0, mystere 6.0 etc)even up with an N20? You set the rules so the N20 is the scratch boat. Open up the beam width to 10' so all the 20s can play. But then you will no longer be the scratch boat.

What about the Hobie Fox? Maybe with a new rig and foils it could be very competitive against the N20s?

The same reason as the other older 20 somethings. By the time you spend the money on new rig and foils it would be less expensive to sell the boat and buy and a N20.

That's called B class(as in A,B,C,D) Tornado dominated it into non-existence. No reason to re-invent the wheel.

I also find it interesting that the name was changed to OPEN when it eliminates the recent boats in the higher performance range. If you are going to create another F18 class that is two feet longer, you should leave it as F20. There is already an open class. If indeed you are trying to set a more open class at least set the width to the Nacra F20 Carbon. I am sure Nacra did a lot of research and found the 10'6" beam to be the best choice for a 20' boat.
