      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.

A-Cat info

30 posts in this topic

Thinking about switching from a nacra infusion to an a class for a number of reasons. I have been finding it hard to find useful info on the wide variety of designs.... Other than the DNA is the go if you have the coin. Looking at the tool or an object but can't find much info on either so if anyone can fill me in on either that would be great. Cheers in advance.

You might try both of these sites when looking at the A-Class for information. You are able to send this message out through the usaca.info site. I do not know if you can do this through the Australian site. I do know that there are currently both a Tool and a coupl of Objects for sale through the Australian site.

Go and do it - its a wonderfull class. I dont know the Object, but the Tool is a good boat. Not the same finish as some of the others (it doesnt make the boat faster, anyway;-). It has more volume and less rocker than the flyers, Bimares etc. and compared to the newer designs it has straight foils and narrover transom. Steve Ashby sailed a tool for a while and beat the nikitas that was around at that time (like Glenn Brewin did in his Flyer)

 

The Nikitas, Scheurer, Visions, DMAs are all good boats as well, but you can get at lot of the joy of an a-cat out of older designs as well (and the difference isnt big, a midfleeter in a new flashy design is still a midfleeter...).

 

Have fun

Its all a matter of how much you want to spend and who you will be sailing against and where you are in the fleet ___ as Lars said a mid fleeter is pretty much always going to be a mid fleeter regardless of the design he is sailing

but the A Group in Aust are a great group of guys

Yeh been looking the objects and tools that are for sale on the aus a-cat site as they are in my price range. After a year or so I'd be looking to upgrade to a competitive design but for the first year it will be a learning curve getting used to the boat and how to set it up. I'm in cairns so the local a-cat scene in very new and small, but have no problem driving around the country to regattas as I do with the F18, so you see me at every nationals/states. Can't help but think I'm going to miss that spinnaker tho lol.

From what I understand the object was released slightly after the flyer. One that was modified a bit came 1st straight boards boat at nationals, so they aren't too slow if sailed well.

I sail an A and a Nacra 20. I held off a couple of years because of the spinnaker mindset also, but I'm happy to inform you that you probably won't miss it at all. The A will keep you plenty busy downwind and the feel (at least for me) is alot like a spin boat. The acceleration on bearaways, because of the light weight, will feel very familiar. Just do it and you won't look back.

Dyslexia?

 

Steve Brewin and Glen Ashby.

 

Steve's ex tool sails out of our club, Im still sailing the capricorn F18. The tool is amazing in light weather, but so are all the a-cats.

 

In the big breeze and waves, the tables certainly turn, the F18 is a lot more stable and user friendly. horses for courses I guess.

I've pretty much decided to go the a-cat just got to sell the F18.... I will miss the 20knt runs out in the ocean but think I will get over it when I don't have to spend 2 hrs rigging. What I want to know I guess is weather the tool is going to be worth the extra 4-5k over the object given I plan to upgrade once I get the feel for an a-cat?

Your size may have some bearing on that decision also. The Tool carries weight decently don't know anything about the object. All things being equal Scarecrow has the right idea.

Yeh defiantly got to loose some weight for the a-cat. Not going to stay at my current weight that's for sure lol.

Sailed a flyer 1 today... Tricky to get in the groove downwind compared to the f18. Amazing upwind performance. Def sold on the idea of an a-cat. Who wants a nacra infusion? Lol

what is the weight range for a newbie A-cat person? have been told 80-85kg, am currently 111kg - maybe I should take on Robnacra's infusion!

Does anyone know the diameter and wall thickness of a carbon, rear, A Class beam? Thanks....

There is no standard size. Different builders and designs use different sized tube beams and some now have "square" beams. IIRC, my Flyer 1 has 90mm rear beam. C-Tech in NZ do a rear beam at 86mm. I believe that some have been as big as 100mm. And it's not just a matter of size. For isnatnce, stiffness can change a lot depending on whether you use high mudulus carbon.

Sorry, I don't. It's got sealed ends and no way of measuring.

The object is quite wide in the stern so carries wt very well. Infant is perfectly suited to having a set of curved foils installed. If you are around 90kg that's what I would get to learn on. High volume makes it very easy to sail.

I'm looking forward to sailing with the new A class boats in Cairns (Tinaroo) in may.Looks like the fleet has gone from two last year (one from Townsville) to about 5? this May (more with Robnacra). It's going to be interesting to see how the Tinaroo fellas make the transition from NACRA 4.5s, Inter 17 etc to the A's. My goal is to pick up a scalp with the Taipan.

Hey Robnacra, Lucas Mcdonald is making me a new A Cat trailer for my Scheurer atm so should be ready to bring back to Cairns in a few weeks or so, if you need a ride for an A Cat feel free to use it, will save me having to go to Brizzy and back...

I cannot really comment on this save to say that when I got a quote from C-Tech recently they were specifying a 86mm ID and 2230mm long with a choice of high modulus carbon or regular.

Dough,

 

I think Bimare V1 crossbeam (2008/2009) were about 94mm OD with probably 3mm thickness and 3kg for the front-beam

 

The rear beam of the NIKITA is around 100mm OD but with hight modulus

 

Cheers
