      A Few Simple Rules   05/22/2017

      Sailing Anarchy is a very lightly moderated site. This is by design, to afford a more free atmosphere for discussion. There are plenty of sailing forums you can go to where swearing isn't allowed, confrontation is squelched and, and you can have a moderator finger-wag at you for your attitude. SA tries to avoid that and allow for more adult behavior without moderators editing your posts and whacking knuckles with rulers. We don't have a long list of published "thou shalt nots" either, and this is by design. Too many absolute rules paints us into too many corners. So check the Terms of Service - there IS language there about certain types of behavior that is not permitted. We interpret that lightly and permit a lot of latitude, but we DO reserve the right to take action when something is too extreme to tolerate (too racist, graphic, violent, misogynistic, etc.). Yes, that is subjective, but it allows us discretion. Avoiding a laundry list of rules allows for freedom; don't abuse it. However there ARE a few basic rules that will earn you a suspension, and apparently a brief refresher is in order. 1) Allegations of pedophilia - there is no tolerance for this. So if you make allegations, jokes, innuendo or suggestions about child molestation, child pornography, abuse or inappropriate behavior with minors etc. about someone on this board you will get a time out. This is pretty much automatic; this behavior can have real world effect and is not acceptable. Obviously the subject is not banned when discussion of it is apropos, e.g. talking about an item in the news for instance. But allegations or references directed at or about another poster is verboten. 2) Outing people - providing real world identifiable information about users on the forums who prefer to remain anonymous. Yes, some of us post with our real names - not a problem to use them. However many do NOT, and if you find out someone's name keep it to yourself, first or last. This also goes for other identifying information too - employer information etc. You don't need too many pieces of data to figure out who someone really is these days. Depending on severity you might get anything from a scolding to a suspension - so don't do it. I know it can be confusing sometimes for newcomers, as SA has been around almost twenty years and there are some people that throw their real names around and their current Display Name may not match the name they have out in the public. But if in doubt, you don't want to accidentally out some one so use caution, even if it's a personal friend of yours in real life. 3) Posting While Suspended - If you've earned a timeout (these are fairly rare and hard to get), please observe the suspension. If you create a new account (a "Sock Puppet") and return to the forums to post with it before your suspension is up you WILL get more time added to your original suspension and lose your Socks. This behavior may result a permanent ban, since it shows you have zero respect for the few rules we have and the moderating team that is tasked with supporting them. Check the Terms of Service you agreed to; they apply to the individual agreeing, not the account you created, so don't try to Sea Lawyer us if you get caught. Just don't do it. Those are the three that will almost certainly get you into some trouble. IF YOU SEE SOMEONE DO ONE OF THESE THINGS, please do the following: Refrain from quoting the offending text, it makes the thread cleanup a pain in the rear Press the Report button; it is by far the best way to notify Admins as we will get e-mails. Calling out for Admins in the middle of threads, sending us PM's, etc. - there is no guarantee we will get those in a timely fashion. There are multiple Moderators in multiple time zones around the world, and anyone one of us can handle the Report and all of us will be notified about it. But if you PM one Mod directly and he's off line, the problem will get dealt with much more slowly. Other behaviors that you might want to think twice before doing include: Intentionally disrupting threads and discussions repeatedly. Off topic/content free trolling in threads to disrupt dialog Stalking users around the forums with the intent to disrupt content and discussion Repeated posting of overly graphic or scatological porn content. There are plenty web sites for you to get your freak on, don't do it here. And a brief note to Newbies... No, we will not ban people or censor them for dropping F-bombs on you, using foul language, etc. so please don't report it when one of our members gives you a greeting you may find shocking. We do our best not to censor content here and playing swearword police is not in our job descriptions. Sailing Anarchy is more like a bar than a classroom, so handle it like you would meeting someone a little coarse - don't look for the teacher. Thanks.

Under 400lb carbon class C, 25ft,14 ft beam,tall rig

Who has foils to make her fly?

Thanks, Stephen Marcoe r2akteamgoldenoldies on fb

The cat pictured is 1991 Little America's Cup Challenger "Freedom's Wing". Designed by Gino Morelli & Pete Melvin who also helped the built, it is the first M&M's first project together. Skippered by Pete Melvin it was defeated by the Australian Defender The Edge III, mainly for the catastrofic failure of the beams during a race.

A class C boat did race the first leg of the 2015/2016 r2ak but not this one.

She has new rudders, Marstrom mast,and the beams look new, so they must of been replaced.

She was raced hard in San Francisco, so the beam issue appears to of been resolved.

She has two mainsails, one over size, another good reason to find lifting boards.

Everyone and their mother is designing lifting foils,at current prices it would be nice to get the right ones on the first try

does the soft sail generate enough power for it to fully foil?

Ronstan was listed in gumtree Australia 6 months ago can't find the ad or remember the price though.

Was sold some time ago, $10k, but this was a re-sell, he had only purchased the boat within the last few years with aspirations of re-doing the foiling C, wing/soft sailed, but I doubt it he finished it, as it was going to be a monster project and the new AD had no new photos, no idea what'd happened to it now, assuming sold again, or given up and locked it away sadly.

You'd have a pretty small pool of potential C-class foil sellers but hey - it doesn't hurt to ask!

Certainly boats out there for pennies on the dollar...are older boats strong enough to take foiling loads??

I could put it the other way round, too heavy for foiling?

I don't think it will be "too heavy" for foiling, just heavier than would be if designed from scratch for foiling. How much? Maybe not enough to really matter; I would agree that getting the right foils (i.e a set from Groupama C's foil molds, which as I understand it may or may not be the same as the foils for the Flying Phantom) are more important than almost anything else. 4 point foiling solution? That would also be trick and probably faster in the water than the 3 point solution, but maybe not on a distance race where the number of tacks and gybes is lower.

Call Rob at Paterson composites.

 

He has foils of a variety of shapes and sizes in stock. We also have tooling down there for the right kind of foils as FYH had a full set built and installed but never tested following the great shit show of 2013.

My guess is the C class is facing extinction. Too many new foilers around, and too expensive. It's a shame. IMHO. Could have been aotherwise if AC hadn´t turned into foilers and small cats

The C class has always been on the verge of extinction, but recall it is also the class that invented the wing sail and brought foiling tech from the AC into beach cat sized boats. I agree there are plenty of new foilers on the market that are easier to go sail than a C with less risk of expensive crashes but there is no box or development rule for them to play in, they don't have the wings and the don't have the design efforts that the C class adds to the mix, nor do they have the speed or grace. I think what happened is Groupama C came in with a big budget, AC level program and re-defined what a modern C is, and its going to take a while for any normal C class to match and/or beat that, so for now, whoever is in possession of Groupama C is the odds on favorite to win. I'm optimistic there will be another exciting development effort for the C class when they pick an appropriate site for their next worlds; we haven't seen how the 4 point foiling solution works in a C, or what the latest U.S or Canadian boats would look like with the knowledge gleamed from the last championship rounds...

Didn't the British team experiment with a pair of Nacra foils at one stage.

@sam

Nothing in the cards right now I am afraid, I / we went all in last time with effort, time etc and it was kind of all consuming. I had to step away from the flame for a bit.

 

Been doing some big cruises with the fam, a Mack here and there, will go see some races in BDA come the spring. Right now just trying to work off the spare tire and get back into some kind of fighting form.

Growing up in awe of AC big & little i always thought the 4 or so years between each session was for a good reason!

Good news, bad news, I found several usable foils, but now wondering what it will take to build up the hulls to handle them.

the good news is the rear beam was built up to handle the huge main sheet loads due to the soft sail, which are very little on a winged boat

That's the concern I brought up cakewalk. It may be more effort than its worth. You can get away with this on the A cat as in reality those boats, pre-foiling, were generally overbuilt due to materials limits and cost (you could build non foiling A cat hulls with some pretty dang thin laminates, like 3oz carbon, but that would triple materials cost, so no one did that). C's are not overbuilt as cost concerns are generally thrown to the wind. Anyway, maybe swap the front beam and the rear beam and do some reinforcing to the old front beam to take the soft sail mainsheet loads? Maybe Hall has some new beams kicking about? Would be curious what Steve suggested regarding this, I'm weighing the move to a high modulus carbon front beam on my A.

Both beams have been replaced to sail in her current configuration,my one day experience was she was hard to hold down, but we weren't using harnesses.

Steve does have trick foils for sale, but no rudders, and we didn't talk about reinforcing. I Thought she could be built up on the outside with minimal effort.

So even though foiling looks fun it may make more sense to race her as is and know when the wind is under 8 knots she is unbeatable. Thanks, Stephen
